Authors: Pu Rong , Lu Shuying , Pu Yuansheng , Tao Zhuomin , Liu Peixue 
Published: September 2019

Abstract
In this paper, we used social network analysis (SNA) method to establish and analyse the network structure of the tourist flow of Jiangsu Province in China based on big data, and built a variable model to analyse its influencing factors. The results show that there is an obvious core-edge structure in the network of tourist flow. The centrality index in the southern region of Jiangsu Province is better than that in the northern region. The road distance is the main factor restricting the flow between regions, and the quantity of trains has a significant impact on the tourist flow. That is to say, a place with convenient transportation is the primary choice for people to travel. High quality of tourist facilities and online tourist products can attract tourists. They are also the driving factors for southern Jiangsu Province to play a great role in the tourist flow network.

Abstract
Taking the accumulation slope of a reservoir abutment in western Sichuan as an example, this paper studies the influence of rainfall duration and rainfall intensity on slope stability with the help of GEO-SLOPE (SLOPE/W module) software according to saturated-unsaturated seepage theory and rainfall infiltration theory. The results show that when the rainfall intensity is constant, the slope stability decreases with the increase of rainfall duration, which presents a slightly slow-fast-slow pattern, and that the slope stability grandually dcreases with the increase of rainfall intensity under the same rainfall duration.

Abstract
An ecological environment is a complex system fundamental to the sustainable development of society and economy. Landsat series satellites are widely used for monitoring the changes in the earth’s surface morphology. With long time series data, Landsat can provide new methods and technical support for eco-environmental monitoring. This study developed remote sensing monitoring methods based on Landsat data to observe the changes in the ecological environment in the Zhoushan region, China. The regional environmental changes in vegetation, water and other key ecological factors were analyzed using multi-temporal remote sensing data. This study shows the effectiveness of this method for the extraction of key eco-environmental factors such as vegetation and water body and the evaluation of regional eco-environmental quality. This study also reveals ecological patterns in Zhoushan region and provides data support for regional eco-environmental assessment.
Characteristics of saltwater intrusion in the Modaomen waterway in the dry season of 2017-2018
Authors: Shuqin Huang , Xiaoling Yin 
Published: September 2019

Abstract
Based on the observations of the Modaomen waterway in the dry season of 20172018 and the hydrometeorological data collected, the influence of runoff, tide and wind on the daily maximum intrusion length is analyzed here in order to researth the characteristics of saltwater intrusion in the Modaomen waterway in the dry season. Compared the daily maximum intrusion length calculated by formula with the observation, it can be found that the two were consistent. Through the correlation coefficient between intrusion length of saline water and flow rate, tide difference and wind, it is found that the movement trend of salinity borderline is determined by the stability of the upstream runoff. Under the condition that the upstream runoff is relatively stable, the movement trend of the salinity borderline is dominated by tide when discharge is high, and when discharge is low, the movement trend of salinity borderline is dominated by the interaction between tide and runoff. And the northerly wind promotes and accelerates the intrusion of the saltwater.
Construction of Loss Assessment Method of Eco-service Value in Sea Area Polluted by Chemical Leakage Accidents Based on Ecological Impact Prediction Model
Authors: Lan Ru , Qiao Bing 
Published: September 2019

Abstract
There is no unified and standardized method for assessing the loss of eco-service value in sea area polluted by chemical leakage accidents. In this study, an index system and a set of assessment procedures for the loss of eco-service value in chemically polluted sea areas are established, and an assessment method based on the ecological impact prediction model is constructed. The validity of this method is demonstrated by taking the northern coast of Hangzhou Bay, that is, the southern sea area of Jinshan District in Shanghai as an example. The conclusion of this study is that once the leakage accident of 2000 tons soluble toxic chemicals occurs in the sea area, 1860 ha sea areas may be affected, resulting in 1.68 billion economic losses; once the leakage accident of 5000 tons oil-insoluble toxic chemicals occurs, 34000 ha sea areas may be affected, resulting in 2.61 billion economic losses.
Estimating the Environmental Cost of Land Use Project

Published: September 2019

Abstract
Environmental degradation is becoming a worldwide problem. However, traditional economic theory often disregards the value of environment in decision making, and the development of land use project usually ignore their damage on the land. As a result, a model needs to be proposed to calculate the cost of environment. We construct an environmental cost evaluation index system for land development projects, in order to calculate the cost of land resources loss. The land resources loss is caused by the destruction of the original land, we analyse it from the value that the land has, including land products value and ecological value. The project pollution cost is resulted from the various pollution that the projects produce after construction, we calculate the pollution treatment cost to estimate the pollution. Moreover, our model can be adjusted to the change of time easily, as we use many constants, such as prices of products and unit grain yield.
Does International Agricultural Trade Matter for Carbon Emissions: A Case Study of the Area Along “the Belt and Road Initiative”
Authors: Yang Ju 
Published: September 2019

Abstract
The research problem of this study is to understand how international agricultural trade affects the carbon emissions. To address this, we have conducted an empirical study based on the panel dataset of 48 countries of 5 regions along “the Belt and Road Initiative” over the period 1995-2014. The impacts of agricultural trade openness on the level of carbon emissions per capita has been investigated. Along with the traditional trade openness, a different trade openness measure is used, called as the adjusted agricultural trade potential index. Based on the findings of the paper, we can draw the following conclusion, that is, the adjusted agricultural trade potential index is negatively associated with the carbon emissions.

Published: September 2019

Abstract
Cultivated land is not only provided with the attribute of natural landscape, but also the carrier of means of production and social form. Some characteristic forms of cultivated land have become the common heritage of human cultural landscape. In recent years, with the change of land circulation and people’s modes of production, the cultivated land form has gradually lost its original characteristic texture. Therefore, how to protect and extend the cultivated land form needs urgent attention and research. The survey selected the existing remote sensing image of Dujiang Dam by Local Space Viewer, interpreted and extracted the schema of cultivated land form in Dujiang Dam, drew the schematic language such as “characters”, “words” and “phrases” according to its scale, and analysed its landscape ornamental value. Then, historical remote sensing was used to analyse the change of cultivated land form in Dujiang Dam, and field investigation and questionnaire distribution were combined to seek the cause and result of the change of cultivated land form. These provide support for future landscape aesthetics research.

Authors: Sychev V N , Sycheva N A 
Published: September 2019

Abstract
The earthquakes and aftershock sequences catalogue of 13 moderate earthquakes occurred in the Tian Shan and the Pamir Mountains from 1983 till 1997 have been examined from the point of view of non-equilibrium thermodynamics using Tsallis statistics and its compliance with Omori-Utsu power-law. It has been shown that the earthquake sequence is the system with memory and long-range correlations. The Tsallis parameter q for the aftershock sequences is larger than the q, calculated for all the earthquake catalogue, which indicates the preservation of increased long-range correlations during the aftershock sequence. Dynamic definition of the parameter q of the four events has demonstrated the sharp increase of the long-range correlations in the target region before the main event and the sharp decrease straight after it followed by return to the average value observed before the mainshock. It has been illustrated that the parameters of the researched aftershock sequences are described by the power dependences and follow the Omori-Utsu law.

Published: September 2019

Abstract
In this work we estimate level of seismic noise at Kyrgyz Network’s (KNET) high-mountain stations for 19 years of the time this network operated in real-time mode (1999-2017). To do that for each channel (E – west-east, N – south-north and Z – vertical, all with 100 Hz sample rate) of each station we made fifteen-minute (900 seconds) segments of seismic noise. We took such segments for different seasons (March, June, September, December) and for various times of day (00, 06, 12 and 18 hours UTC) for the whole 19 years. We analyzed probabilistic power spectral density heatmaps and found out some features of KNET’s high-mountain station’s operation. These features depend on season-wise weather changes. The worth month for all stations is September. In general, when weather is favorable these stations can be characterized as low-noise ones and their data may be used in various researches.

Authors: Zolotukhin D E 
Published: September 2019

Abstract
Possibility of a tsunami as a result of an earthquake is estimated by magnitude and geographical criterion now. The earthquake is considered tsunami-danger if his epicentre gets to a tsunamigenic zone, and intensity exceeds the set threshold value of magnitude. The solution of such task as specification of magnitude and geographical criterion for the announcement of alarm of a tsunami in the Sea of Japan and in the water area of the Pacific Ocean to the east of the Japanese islands is extremely relevant. For the purpose of specification of magnitude and geographical criterion of tsunami risk of earthquakes in these areas the author executed a series of computing experiments. During the computing experiments the centres of real historical tsunami in these water areas were modelled. At creation of the model centres of a tsunami the Okada model was used. Based on the analysis of statistics of historical tsunami and results of numerical modelling by the author the redundancy now in use by Service of warning of a tsunami in the Far East of Russia magnitude a tsunami risk threshold is shown.
Analysis of the main characteristics of tsunamis based on data from deep-ocean stations
Authors: Yu Korolev P , Korolev Yu P , Loskutov A V 
Published: September 2019

Abstract
A tsunami in the ocean, according to one idea, is a long wave with a practically unchanged period and a relatively slow attenuation. According to others, the dispersion affects the evolution of a tsunami, the wave period increases with time, and the amplitude attenuation is more rapid. This study investigates the transformation of tsunamis from source to coast, including the change in amplitude and duration of the head waves with distance. It is shown that the dispersion does affect the evolution of the tsunamis. The moment of dispersion manifestation depends not only on the magnitude of the earthquake that caused each tsunami, but also significantly on the depth of the ocean in the focal region.

Authors: Shabaganova S N , Tarabukina L D , Kozlov V I 
Published: September 2019

Abstract
On Aug. 29, 2016, the tropical cyclone Lionrock was reported to turn into an extra-tropical storm and go to the shore of the Primorsky Region as monitoring shows, which brought about significant precipitation growth recorded in the north of the coast. Many surveys show the tropical cyclones in this area to transform into extra-tropical ones and become powerful mid-latitude storms with significant damage to coastal and maritime areas. The paper uses WWLLN (World Wide Lightning Location Network) data to study the thunderstorm activity while the tropical cyclone reaches the typhoon level with the maximum wind velocity. This made it possible to identify parameters’ variations of thunderstorm activity during atmospheric vortex phenomena. It also enabled us to determine the emergency probability due to a thunderstorm.
Space-time variability of wave characteristics near the coasts of the Southern Kuril Islands
Authors: Borisov A S , Kirillov K V 
Published: September 2019

Abstract
Significant wave heights and most probable wave heights in the nearshore areas of the Southern Kuril Islands are considered in this paper. These characteristics were obtained from data of in-situ measurements of hydrostatic pressure in the depth range from 5 to 25 m. The measurements have been performed in 2008 and 2009. It is shown in the paper that relatively calm sea surface was observed in time period from July till first half of September. Most probable wave heights varied from 0.17 m to 0.27 m and maximal values of significant wave heights varied from 0.75 m to 1m in the depth range from 15 to 25 m. For depths less than 15 m most probable wave heights varied from 0.05 m to 0.1 m and maximal values of significant wave heights varied from 0.68 m to 1m. Time period from second half of September is characterized as stormy period. Maximal values of significant wave height reached 5 m at that time and most probable wave heights varied from 0.1 to 1 m depending on depth and location. Period from January till April can be characterized by high number of moderate storms with maximal value of significant wave heights 1.8 m and most probable wave heights from 0.13 to 0.33 m.
New data on the morphology and development of volcanic lakes of the Kuril-Kamchatka region
Authors: Kozlov D N , Lebedeva E V 
Published: September 2019

Abstract
Volcanic lakes are of particular interest to geomorphologists and other professionals due to the diversity of the basins forms and the very dynamic development of lake systems. The origin and evolution of these water bodies are closely related to active volcanic and post-volcanic processes, they are characterized by rapid changes of shape, level, composition of water and characteristics of the coast. Usually bounded by craters, calderas and in the immediate vicinity of volcanoes, these lakes present a kind of by-product of volcanism. In the Kuril-Kamchatka region, two types of lakes can be distinguished: 1) dynamically developing young, some of them ephemeral, located on active volcanoes, in active craters. In these lakes, as a rule, there are active gas-hydrothermal manifestations, and their waters are highly mineralized; 2) stable (relict) lakes in the calderas of dormant and extinct volcanoes. Lakes of this type usually do not have explosive funnels or active gas hydrotherms, and the water in them is slightly mineralized. It suggests a much more ancient age and the decreasing of post-volcanic activity in caldera depressions. Lakes of different types can exist close to each other and form a single communicating systems.
Coastal retreat at Kharasaveyskoye gas and condensate field area, Kara Sea, Russia since 1970s
Authors: Belova N G , Ogorodov S A , Shabanova N N , Maslakov A A 
Published: September 2019

Abstract
Changes in coastal retreat rates, both spatial and temporal, are considered at the area of Kharasaveyskoye gas and condensate field for the period before the exploration till now. In the study area, the presence of permafrost makes the erosional coasts vulnerable to rising temperatures. The increase in air temperatures contributes to the thawing of coastal sediments and their accelerated destruction. And a decrease in sea ice area potentially increases the wave fetch. The rapidly changing climate of the Arctic should influence the processes of destruction of frozen coasts. At West Yamal Peninsula near Cape Kharasavey the average coastal retreat rate is 1.1 m per year (1977-2016) for 7 km of coastline. Based on the analysis of multi-temporal aerial and space images, it has been established that the maximum retreat rates are typical of coastal segments composed of icy sediments. As for temporal variability, the maximum rate of destruction was observed in 1977-1988 (up to 6.5 m per year) immediately after the beginning of economic development of the territory. In this key site, human impact affects the rate of coastal destruction more than variations in hydrometeorological parameters.
Vetrovoy isthmus of iturup island – holocene strait
Authors: Afanas’ev V V , Ignatov E I , Uba A V , Dunaev N N , Leontiev I O , Gorbunov A O 
Published: September 2019

Abstract
Explosive volcanism is equally important as the features of neotectonic and modern movements for the development of the Kurile Islands coast, as it led to the afflux of hundreds of millions of cubic meters of pumisopyroclastic material and tephra into the wave processing zone of coastal zones of the Pleistocene-Holocene. Morphometric, georadar and paleogeographic studies of the coastal-sea relief of Iturup Island allowed to determine several levels of marine terraces in the pyroclastic sediments of the Late Pleistocene-Holocene, and also the presence of a buried sea strait that existed at least in the middle Holocene. Taking into account the values of deformation of the terrace levels, the depth of the strait was 10-15 meters. Volcanic-tectonic deformations connected with eruptions near the central part of the Vetrovoy Isthmus led to the collapse of pumice packs at the section basement of the sea coastal ledge with a layer of beach material on the roof (LU-9223-6320 ± 100, cal. Year BP). Thus, in the mid-late Holocene, after the sea level was risen to the nowadays levels, at least two more pyroclastic series were deposited, the last of which one is dated 1050 ± 70 cal. BP – LU-8685.

Vegetation of the Yuzhno-Sakhalinsky mud volcano as an indicator of activity
Authors: Kopanina A V 
Published: September 2019

Abstract
In the present paper we have addressed the issue of identification of mud volcanic activity based upon the vegetation, its structure and dynamics, as well as the structural peculiarities of woody plants. The study was conducted using an integrated approach which includes: the description of vegetation and the structural analysis of woody plants that grow at various distances from the eruptive centre of the volcano. The obtained data on the vegetation suggest that the Yuzhno-Sakhalinsky mud volcano is a far more extensive landscape feature that it was considered before, with an eruptive centre which changes its location every 150-300 years.
