Authors: Efremov S , Logvinova Y , Russkova I , Polyukhovich M
Published: August 2020

The development of the Arctic shelf involves the development of mineral resources and monitoring of the environmental situation in the Far North with the implementation of work outdoors in extremely adverse weather conditions. In this case, it is necessary to take into account the stable constancy of negative temperatures. Work on a rotational basis does not solve this problem. This article proposes a methodology for taking into account environmental parameters when assessing the working conditions of nonstationary workplace. As an example, an assessment is given of the workplace of the lineman of main pipeline. It is proposed to use geographic information systems as a technology that allows determining environmental parameters. The responsible person quickly and thoroughly evaluates the work environment based on the existing spatial reference of information to various non-stationary workplaces. The proposed method for assessing and optimizing the time of work will not only minimize technological risks as a whole, but also minimize the damage to the health of workers who are forced to perform work in extremely adverse conditions.

Published: August 2020

According to the literature, linear-exponential mathematical models have been developed that link the magnitude of the risks (probabilities) of fatal outcomes when metal cations affect daphnia in a wide range of concentration variations. The approach to a comprehensive assessment of heavy metal pollution of surface waters of land has been improved (risk of combined exposure). The classification of water quality is given depending on the magnitude of the combined risks. The broken-stick model was used in order to classify water quality according to metal contamination levels. The developed approach was applied for an interannual assessment of lake pollution. The results of ecological and toxicological assessment of the dynamics of metal pollution (such as iron, manganese, zinc, copper, nickel, cobalt, lead, chromium, mercury and cadmium) of the Bienda-Stemme lake, located in Western Spitsbergen (Svalbard), in the spring of 2003-2019 are presented. It was established that the quality of the Bienda-Stemme lake water varied from “good” in 2003-2004, 2013-2015 to “satisfactory” in 2017 and 2018. In the period of 2007-2012, as well as in 2019, the water quality of the lake was characterized as “very good”. On average for the period of 2003-2019 the water quality of the lake in the spring was characterized as “good”. The main contribution to the metal pollution of the Bienda-Stemme lake is due to compounds of copper, mercury and zinc. A significant advantage of the considered approach to assessing the pollution of the Bienda-Stemme lake by metals is that this approach does not use the system of federal standards for MPC (maximum permissible concentrations). Moreover, up to present, regional standards have not been developed in Russia.
The role of fucus algae in bioremediation of coastal waters of the Barents Sea from oil products
Authors: Voskoboinikov G , Malavenda S , Metelkova L
Published: August 2020

There was estimated the contribution of Fucus algae to the removal of diesel fuel (DF) from the Kola bay of the Barents Sea. The calculations are based on the results of: 1) expeditionary observations of recent years of the reserves, distribution and biomass of fucoids of three parts of the bay and 2) laboratory studies of the ability of four types of fucus (Fucus vesiculosus, F. distichus, F. serratus, Ascophyllum nodosum) to neutralize the toxic effect of diesel fuel. It was shown that the reserves of fucus are 4720 tons of wet weight. The absorption capacity is maximum of F. vesiculosus, and decreases in the series of F. distichus ≥ F. serratus ≥ A. nodosum. The calculations showed that fucoids of the Kola Bay can absorb and recycle about 850 kg of diesel fuel in 5 days. The existing rows of Fucus algae of the Kola Bay are an important element in the implementation of preventive, everyday cleaning of the bay waters from oil products. The inclusion of data of the ability of other representatives of phytobenthos to neutralize DF could increase the role of algae macrophyte in cleaning the coastal marine water from oil products.

Published: August 2020

Far Eastern Arctic territories, poorly developed in comparison with the northern territories of the European part of Russia, are drawing increasing attention from the world community. Their uniqueness and identity, rich and diverse natural resource potential, great prospects for reclamation and development on the one hand, and harsh climate with extreme conditions, permafrost, fragile natural environment sensitive to human impact on the other hand create the problem of balancing reclamation and preservation of the features of this unique ecosystem. The prospects of these territories depend on the choice of the most reasonable, economically and environmentally sound development blueprint. The existing ecological and economic situation in these territories needs to be studied to determine possible changes in the relations of production and nature, which is the purpose of this study. The methods of comparative statistical, historical and cartographic analysis describe the studied regions, the dynamics of environmental management and the environmental situation as a result of reclamation in the context of ulus and districts. The need and priority of activities divided by types of structural directions of environmental management are also determined. The obtained results allow the reasonable determination of the main priority areas of activity. They include: balanced ecological and economic development of the Arctic territories of the Russian Far East, considering the development of traditional employment sectors of the indigenous peoples of the North, their own food security for the region is guaranteeing (diversification of the economy of the traditional industry through the development of food processing, handicrafts, souvenirs production, and tourism). It should be taken into account by the planning and governing bodies when drawing up plans for the socio-economic development of the territories in question.

China’s participation in the international scientific cooperation in the Arctic
Authors: Yaxin W
Published: August 2020

The article analyzes the role of China in the most important areas of international scientific cooperation in the Arctic, in which non-Arctic players are involved along with the Arctic countries. The legal basis for scientific cooperation in the Arctic is the 1982 UN Convention on the Law of the Sea, the other is the Arctic Council. In 2013, China became the official observer state of the Arctic Council, thus taking an important step towards participating in Arctic international cooperation. Despite the fact that China is a non-Arctic country, factors such as climate change in the Arctic, the prospects for the development of the region’s resources and the Arctic Channel contribute to China’s interest in the Arctic and its policy towards the region. Taking into account the interests of China in the Arctic, as well as the legal framework and responsibility in the Arctic, under the existing mechanisms of international cooperation in the Arctic, China is involved in a number of Arctic international scientific research, mainly in the field of natural sciences. At the same time, China introduced its new platform for international cooperation in the Arctic – the Polar Silk Road, which is making some progress in international scientific cooperation.

Published: August 2020

In this article, an attempt is made to create a model of global processes influence on the development of the Arctic territories of circumpolar countries. A characteristic of the Arctic territories as a research object is given from the point of view of the territorial, geographical, natural and climatic features, as well as globalization processes such as transnationalisation, scientific and technological progress, market competition. A hypothesis of the global processes influence on the development of the Arctic is formulated. Methodology for creating a model of the global processes influence on the development of the Arctic territories of the circumpolar countries is proposed including the formulation of the research objective, the rationale for the selection of endogenous and exogenous variables, and the creation of a model. The research objective was to create a model of the globalization processes influence on the Arctic development. The indicators reflecting the economic, social, and environmental development of the Arctic territories of the circumpolar countries were selected as endogenous variables. They include the average annual increase in the gross regional product, the share of agricultural products in the gross regional product, the share of industry in the gross regional product, the number of economically active population, the number of unemployed people, and carbon dioxide emissions. The indicators characterizing globalization processes were selected as exogenous variables: the average value of the transnationalization index of the largest transnational corporations (TNCs), world exports of goods and services, royalties and license payments, traditional fuels consumption, electricity consumption per capita, the volume of foreign direct investments. The authors propose a dynamic econometric model consisting of eight econometric equations, each of which is an ADL model that takes into account the time factor. The results of the analysis will be used by the authors in further studies to make forecasts and develop a concept for the development of the Arctic territories of circumpolar countries.

Published: August 2020

The article is aimed on analysis of digital infrastructure as the factor of economic and industrial development of the three Arctic regions of Russian North-West: Murmanskaya oblast’, Arkhangelskaya oblast’ and Komi Republic. These regions faced serious social and economic problems last years. The only way to solve these problems is reindustrialization and technological modernization. Modern industrial technologies are based on the digital transformation of all business processes of enterprise. That’s why the regional digital infrastructure, information and communication technologies availability is an important factor of economic and industrial development of the regions. The article uses the method of calculation of integrated indicator characterizing the level of development of the digital infrastructure of the regions and proposed a formula for computing the numerical value of the integrated indicator. The formula allows receiving numerical results of calculation, based on data of the state official statistics regarding separate indicators aggregated into two groups. The indicators of the first group characterize the material factor of the digital infrastructure of the region. The second group reflects the real ability of regional business use of information and communication technologies and software. The calculations of the integrated indicator dynamics for the period when statistic data are available for three regions allowed to figure out main factors making impact on the level of digital infrastructure development and formulate recommendations for the future.

Authors: Simakova A V
Published: August 2020

The regions of the Republic of Karelia entered the Arctic zone later than the rest of the Arctic regions. Therefore, the important issue is the formation of positive attitudes of the population regarding the “Arctic benefits” of the regions of Karelia. The article presents the results of a study on informing the population about the Arctic status of the territories of the Republic of Karelia and the corresponding expectations of the local population from the assignment of the Arctic status to the territories. The purpose of the study is to determine the level of public awareness of social perceptions regarding the state and prospects of development of the Arctic territories of the Republic of Karelia. For the study, methods of content analysis and sociological survey of the population were used. Local media broadcast the general agenda of the republican media on the prospects for the development of the Arctic regions. However, no information is provided on the individual benefits to the area. Most residents of the Republic of Karelia know that they live in the Arctic zone, but do not associate high expectations for the development of territories with the Arctic status. Informing residents of the Arctic regions and the Republic of Karelia about the possible prospects for the development of the Arctic territories is not enough. Based on the results of the study, recommendations are presented on improving the policy of informing the population about the benefits of the Arctic status of the territories of the Republic of Karelia.

Published: August 2020

In the modern world, the development of the Arctic and Antarctic regions is becoming increasingly important due to their resource attractiveness and, in the context of global warming, their potential use as new routes of transport connection. Of course, in this context, the development of infrastructure is of a particular importance, for example, in the Russian Federation, due to the raw material orientation of the economy, many cities located in the Arctic and Subarctic zones are built around a city-forming enterprise aimed at the extraction or processing of raw materials, such situation results in a fairly substantial list of problematic questions. This study focuses on the analysis of the position and role of single-industry cities in the development of the Arctic region of the Russian Federation. The conclusions and results obtained in the following work may be interesting in the context of studying impact factors on the development of the Arctic and Subarctic territories of Russia. Also, this work is aimed at developing proposals for changing the situation in single-industry cities in order to accelerate the development of this region and improve the overall economic situation, in the aggregate, this can be useful in developing territorial development strategies not only for government bodies and programs, but also for private companies interested in investing in development projects.
The Role of the Russian Arctic Gas Industry in the Northern Sea Route Development
Authors: Katysheva E G
Published: August 2020

The Russian region of the Arctic has been described in terms of unique hydrocarbon potential, as well as strong concentration of major natural gas fields. The article presents reserves of natural gas, oil and condensate in the main oil and gas provinces of the Russian Arctic. It is indicated that the development of Russia’s economic activity in the Arctic depends largely on the increased transport and infrastructure capacity of the region. The activities of the largest Russian extractive industries such as PAO Gazprom, PAO Rosneft Oil Company, PAO NOVATEK for the production of natural gas in the Arctic zone have been described. The implementation of the integrated investment project “Yamal-LNG”, which provides for the production of natural gas at the Yuzhno-Tambeyskoye field, its liquefaction, and supply to consumers has been singled out as one of the most significant areas for developing the resource base of the Arctic zone. The article touches on the production capacities of a liquefied natural gas (LNG) plant, as well as the logistic structures for delivering LNG to consumers. It is also indicated that transportation of liquefied natural gas along the Northern Sea Route has a variety of significant advantages. Review of the activities carried out by Russian companies in the development of the Arctic gas fields has revealed the relationship between the processes of implementing gas projects in the region and the rate of development of the Northern Sea Route (NSR). The dynamics of cargo transportation by the NSR has been analyzed and also external and internal factors that determine the effectiveness of the functioning of the NSR transport system have been highlighted. Current state of the icebreaking fleet has been appraised as one of the most important drivers in cargo transportation along the NSR. Availability of liquefied natural gas as marine fuel has been discussed as one of the advantages of the NSR, which will allow observing stringent environmental standards of shipping in the Arctic and reducing freight costs. Conclusions have been drawn on the high importance of gas production projects to be implemented in the Russian region of the Arctic for the development of shipping along the Northern Sea Route.

Based on interdisciplinary approach use, the authors analyzed the basic laws of the formation of the environment of the circumpolar region, among which special attention was paid to the natural-climatic, geographical, physical and social features. The authors revealed that the development of the habitat by Arctic aborigines was formed with ecologically sustainable Arctic environment and habitats of ethnic communities preservation, which characterized by the heterogeneity of its natural and cultural landscapes. Features of the domestic way of life and sustainable traditions of economic activity had a significant impact on the formation of the Arctic habitat. Reindeer herding based on the breeding and use of reindeer, hunting of large marine animals, such as seals, walruses and whales, fishing, hunting and wild plants gathering were main activities.
The correlation of the values and hardiness of the inhabitants of northern Russia
Authors: Sivrikova N V , Postnikova M I
Published: August 2020

The study examines the correlation between value orientations and hardiness in the context of human capital development in the Arctic. Hardiness is one of the factors of resistance to stress and life difficulties. It plays an important role in the survival and maintaining a high level of efficiency in the conditions of northern Russia. The purpose of this research was to study correlations between value orientations and the level of hardiness of residents of northern Russia. The sample was 171 residents of Arkhangelsk. The Terminal Values Questionnaire, Sch. Schwartz’s questionnaire (adapted by V. N. Karandashev) and the «Hardiness Survey» (adapted by D.A. Leontiev) were used to collect empirical data. The results of the study showed a correlation between pragmatic values and the level of hardiness. A correlation of the level of hardiness with the values of public life was established too. A regression model built on empirical evidence showed low potential in predicting the level of hardiness of value orientations such as spiritual satisfaction and own prestige. The authors concluded that value orientations are one of the factors of the level of hardiness, as they can explain only 18% of the variance of this variable.

Published: August 2020

This paper outlines the concept of sustainability in regard to regional development, examines basic premises of modeling regional relations in the Arctic zone of the Russian Federation, describes the principles and investigates the specifics of building models for sustainable development in regions of the Arctic. It presents methods to build a model that can fully characterize sustainable regional development in the Russian Arctic and lays out requirements for such a model and its corresponding indicators. The paper also considers possibilities for using and adapting already existing mathematical models exemplified by an autoregressive distributed lag (ADL) model and a neural network model. The authors specify under what conditions these models can fully meet all the requirements, what statistical indicators are of key importance to a numerical representation of sustainable development, what factors can be prioritized to be incorporated in the models, what limitations they have and why these very models show the most promise in terms of both analyzing the current state of affairs and making forecasts. The paper presents the results of testing the models on the basis of real statistical data gathered across the Murmansk region and compares the derived outcomes to draw conclusions from the obtained data. It also summarizes the findings from the built models and assesses the prospects for their further application in forecasting sustainable regional development and utilizing projected outcomes in making management decisions to implement the strategy for the development of the Russian Arctic regions.
Experience of research of the topic of digital inequality in the Arctic based on ideas of German sociologists and psychologists
Authors: Vinokurova U , Shachina A , Shachin S
Published: August 2020

The article is devoted to the problem of digital inequality in the Arctic in the entire complexity of this problem. It cannot be reduced only to providing all Arctic communities with equal access to digital devices and technologies. Even in this area, there is a need to combine different ways to solve this problem – the development of a fiber optic network, as in Murmansk, and satellite Internet, as the Republic of Sakha (Yakutia). However, this problem has a serious humanitarian component, consisting in the need to develop a culture of using digital technologies. This means an awareness of the challenges and dangers of the one-sided development of a personality in case of neglect of other forms of activity in the world, except for staying in virtual reality, as well as the danger of dominance in society such as individuals who are not able to distinguish a subject from an object, not capable of self-control and responsible actions. The culture of using digital technologies presupposes the establishment of a reasonable framework for their application and public control of them, which will put them at the service of the development of humanity in interpersonal relationships and the people themselves. As a result, digital technologies will be able to synchronize unrelated processes in the Arctic based on the information that is presented in digital form. It is on this basis that relations of cooperation between various actors in the development of the Arctic can be established, which will allow to achieve the effect of the synergy of their actions in the process of the spread of digital technologies in the Arctic.
Features of inclusion of people with disabilities in regional conditions
Authors: Zhigunova G V
Published: August 2020

Social inclusion implies equality of opportunity and equal participation of individuals in society. The key to social inclusion for people with disabilities is the creation of a barrier-free environment. This process has been carried out systematically in Russia and abroad in recent decades. The results of a qualitative study conducted by the author in 2019 in the territory of the Murmansk region among people with disabilities showed that the nature of the disease and their individual and personal characteristics, the state of urban planning and mental environments, employment and material situation, the presence of family and loved ones and many other factors play an important role in the independent life of persons with disabilities.. The main ways of achieving inclusion of persons with disabilities are related to the solution of various difficulties at the level of the State and its social institutions - the implementation of measures to increase the accessibility of infrastructure, public spaces and transport, the provision of technical means of rehabilitation, the improvement of the accessibility and quality of medical care, the improvement of the material situation of persons with disabilities, employment and education. The study showed that the state of health of persons with disabilities directly affects the level of their social activity, but not the opportunity to participate in the life of society. The level of social participation of persons with disabilities today depends not so much on the level of accessibility of social infrastructure as on their desire to participate in society and the availability of adequate assistance and support. In this regard, it is important to work to ensure the satisfactory psychoemotional condition of persons with disabilities, their families and loved ones, as well as institutions of social assistance and support.
Optimization of the robot motion law by the criterion of minimizing maximum instantaneous power and electric motor size
Authors: Volkov A , Kornilova A , Matsko O , Mosalova A
Published: August 2020

Maximum instantaneous power consumption of robot drives determines requirements for power supply systems and dimensions of drives for robots and different process machines. The tasks of minimizing peaks in power consumption and drive sizes are acquired when creating autonomous robots operating under restrictions for installed capacity and weight-size parameters of the equipment. For a large number of such robots there are no process restrictions for types of applied motion laws and their numerical characteristics: maximum speeds and accelerations. The motion law type and especially its parameters are traditionally determined by the designer preferences without any justification. These are, for example, restrictions for maximum accelerations or speeds. The first is usually associated with the need to ensure strength and accuracy of the robot, the second - with safety of service personnel in the robot working area. Using the example of one of the most common motion laws the relation of instantaneous power and energy consumption on the payload are studied. Results of this research can be used as a basis for robot drives design in view of accepted criteria when optimal parameters of the motion law are calculated for each drive operation cycle depending on anticipated or actual load.

Published: August 2020

The low-sulfide palladium deposit North Kamennik is confined to the North platinum-bearing reef in the West Pana intrusion of the Paleoproterozoic Fedorova-Pana layered complex of the Kola Peninsula. The main ore body of this deposit is accompanied by underlying ore bodies, which is not typical of other sites of the North Reef (e.g., Kievey deposit). The lower ore bodies, differing from the main one in composition of the host rocks and geochemical characteristics, are divided into three types. The conducted mineralogical studies allow us to determine each ore type according to the PGM assemblage — stannide-telluride (type 1), arsenide-sulfide-telluride (type 2) and sulfide-telluride (type 3). Mineralogical finds have been made within the ore bodies of stannide-telluride and arsenide-sulfide-telluride PGM assemblages and are presented by arsenopalladinite, isomertieite and kojonenite (new minerals for the North Reef).

The paper considers Russia’s position in the system of European energy policy on the natural gas market. We have analyzed the interest in natural gas exports in the context of maintaining the energy security of EU countries, stimulating in turn the interest towards the Arctic oil and gas reserves as a means of increasing supplies. We have established the role that diversification of transportation means plays in ensuring exports. We have described the capacities of the main pipelines transporting gas to the EU countries. We have substantiated why investments should be made into establishing and improving the transport infrastructure in the Arctic, specifically, developing the routes for transporting natural gas.
Shaping of a writing researcher’s identity
Authors: Zashikhina I
Published: August 2020

The article highlights the problem of writing for publication research purposes and its impact on a beginning scientist’s identity. The author points out two aspects of research writing and publication in international indexed journals. The first aspect is the developed skills of academic writing in English. The second aspect is the knowledge of research methodology and scientific publication design. The paper views the use of the two mentioned skillsets through the lens of English for Scientific Research module. During the module, the doctorate students of Northern (Arctic) Federal University were offered a survey consisting of three blocks of questions. The students’ answers were further developed through Socratic questioning technique in order to investigate the students’ identity formation. The findings reveal a severe lack of confidence among beginning scientists in relation to the research publication process, particularly to the methodology of research. The author concludes that the challenges of the research publication process impact the identity of a junior scientist in a negative key. The study demonstrates that beginning writing scientists need a thought-through professional assistance in the area of publication research, especially research methodology so that they could build a strong identity, necessary for their development in the international scientific community.
Modeling of the rainbow trout feeding in the cage complex of the «Russian Sea - Aquaculture» company
Authors: Beloborodov A , Minchenok E
Published: August 2020

The paper describes three models of feeding rainbow trout used in the cage complex of LLC “Russian Sea - Aquaculture”. It is shown that the most effective is the method that combines models of three, two, and one-time feeding of rainbow trout. Fish diseases negatively affect feeding efficiency. With the onset of diseases, feed intake decreases sharply. Under marine conditions, rainbow trout are often affected by the salmon copepod Lepeophtheirus salmonis, which damages the mucous membrane and feeds on the blood of fish. Timely use of medicinal feed and chemical delasing has a positive effect on the physiological state of fish and feeding efficiency is restored. It was found that when choosing a feeding model, it is necessary to take into account the length of daylight hours. With an increase in daylight hours in fish, feed saturation increases, and with a decrease in daylight hours, on the contrary, decreases. Maturity stage in cage trout occurs faster than in wild-living individuals, which must also be taken into account when drawing up the feeding regimen. When developing a model for feeding rainbow trout, it is necessary to control the content of dissolved oxygen in the water. With a decrease in oxygen concentration, the fish experiences stress, and food saturation decreases. It has been established that the main factors affecting the choice of feeding model are water temperature, daylight hours, average weight of fish in the cage, physiological state of the fish and its maturity stage. The selection of the most appropriate model should be based both on the biological characteristics of the fish grown and on environmental factors.
Re-finding of sipunculoids (Sipuncula) in the Kola Bay’s area of the Barents Sea in 2017-2018
Authors: Garbul E , Pavlova L , Garbul (Antsiferova) A
Published: August 2020

Sipunculoid fauna of the Kola Bay was first described by K. M. Deryugin in 1915 on the benthos samples collected using a dredge and Sigsbee trawl. Further studies of zoobenthos applying quantitative methods (Petersen grab), conducted by V. I. Zatsepin in the 1930s revealed the presence of dense colony of these invertebrates in the water area of the Kola Bay. Further, the formation of new towns and settlements, infrastructure development, construction of port and industrial facilities, military and naval bases on the bay’s coast led to the rapid integrated pollution of the water area and bottom sediment, which consequently caused the rapid regression of Sipuncula colonies. In 2003, near the village Mishukovo, the latest instance of worms related to the phylum Sipuncula was detected. Further large-scale benthic surveys conducted in the southern, middle and Northern bends of the Kola Bay, indicated a complete lack sipuncuolids in the study area. New Sipuncula settlements, according to the survey conducted in 2017-2018 in the Kola Bay, make assertions about the significant reduction of human-induced impact on the fauna of the bay.

Published: August 2020

In this paper, we study the spatial and temporal variability of the Bering sea ice cover. The Bering sea is a major transportation importance as a link in the Northern sea route in turn every activity at sea, meeting the challenges of hydro-meteorological research and predictions in this region largely depend on the knowledge about ice conditions. Observing changes in the ice environment can also serve to assess climate change. For the study, the methods of mathematical statistics applied to data on the amount of ice as a percentage for the Bering sea area in the 1x1 degree grid for the period November 1981goda-April 2014. In the course of the work, the trend component of the time variability of sea ice was identified, spectral and harmonic analysis was performed, and autocorrelation analysis was performed. As a result, for long-term variability, the existence of a trend in the development of ice conditions was revealed, and the presence of a linear trend is unlikely.

Authors: Fu Guanjun , Xu Zhicheng
Published: August 2020

In the new era, China’s energy development is facing a series of new propositions. The formulation of energy strategy needs to adapt to the changes of the internal and external environments. Based on the analysis of energy strategy evolution for China and different countries in the world, this paper proposes the influence mechanism of the internal and external environments to energy development based on the driver-state-response model, and draws on the PEST model to construct a three-level evaluation index system for energy strategic environment, in which the external environment includes four first-level indicators of international environment, political environment, economic environment as well as social environment, and the internal environment includes five first-level indicators of energy resources, energy supply and demand status, energy infrastructure, energy technology and energy market environment. The index system of energy strategic environment assessment constructed in this paper can provide a reference for China’s energy strategic analysis.

As one of the five major transportation industries, pipeline transportation is an essential energy-transportation tool. China is in an earthquake-prone area. Earthquake is a vital factor for pipeline damage. For this reason, FLAC3D numerical simulation is used to study the dynamic response of pipelines under earthquake wave loads. The dynamic response can be mastered by analyzing the changes in acceleration, velocity, and displacement. The research results show that the destruction of the underground pipeline is mainly due to the earthquake wave effect and the displacement of the surrounding rock of the pipeline. The pipeline has the effects of increasing the earthquake wave acceleration and amplifying the earthquake stress, and it also causes the loosening of the surrounding rock of the pipeline. The pipeline after the earthquake is challenging to repair quickly, and it causes more secondary earthquake disasters. The research results are of great significance for reducing the damage caused by earthquakes to pipeline transportation projects and guiding the earthquake design of underground pipelines.

The work of comprehensive improvement for urban rivers has been put on the daily agenda. This paper introduces in detail a comprehensive treatment scheme integrating anti-pollution, treating-pollution and monitoring maintenance in views of both the perspective of technological process and the analysis of pollutant causes. The most important thing of pollution prevention is to prevent pollutants from entering the river again. Means such as low impact development technology and laying pipelines to collect wastewater for intercepting can be adopted. The most important process of pollution treatment is dredging sludge of rivers in time and repairing water body by using ecological principles. The process of monitoring and maintenance includes monitoring of water quality in real time, regular monitoring of water ecosystem, monitoring of normalized pollutants and timely cleaning of garbage and removal of various pollution sources, which could guarantee and maintain the river’s healthy state. The three steps of river improvement promote each other and form a circular relationship. According to this scheme, the comprehensive improvement for urban rivers needs the participation of government, enterprises, society and residents, which may achieve the ultimate goal of sound ecological balance of the ecosystem. In addition, this paper gives the simple operation process of river improvement and the simple idea of sludge treatment, which provides valuable reference for improving the water treatment system.
