Application of geodata for operational study of population placement and movement
Authors: Vorobyev A N 
Published: January 2021

Abstract
The aim of this article is to develop a methodology for compiling population density and mobility maps based on the data (geographic data) obtained from mobile operators in Irkutsk. Before its development, Russian and world experience in compiling maps based on mobile phones data was analysed. To achieve the aim, the author uses the data received from mobile operators (CDR), with which it was possible to identify information about the location of the device at any time. Based on the geographical location of base stations, one can analyse the density of users at a particular time and place. Based on the results of spatial data analysis, we obtained the signal density at a particular time. The results obtained now clearly demonstrate that geographic data from user devices and geographic information systems represent a very effective symbiosis of technologies, which serves for solving geographical problems. Such studies assess the general mobility of population for a particular region. Data on the location of a mobile phone can reveal the spatiotemporal distribution of urban residents at macro-and meso-levels in administrative districts of the city.
Investments in fixed capital and the prospects for sustainable development of the eastern border regions of Russia
Authors: Faleychik L M , Faleychik A A 
Published: January 2021

Abstract
The article is devoted to the analysis of the economic effects generated by the investments in the economy of the eastern border regions of Russia: the subjects of the Far Eastern Federal District and the Baikal region. Interregional comparisons and contrasts of the economic development indicators for 2011-2018 are given in comparable prices with 2011 as the base year. We discuss the factors hindering the accelerated growth of the economies of these regions. Particular attention is paid to the structure of investments in fixed assets, their effectiveness and impact on the specifics of the socioeconomic development in individual regions. There are multidirectional tendencies in the socioeconomic development of the studied regions. An analysis of investment flows and indicators of socioeconomic development in the eastern regions of the Russian Federation reveals that the existing institutional environment does not yet ensure sustainable economic development in the east of Russia. The integration processes here are hampered by an excessively strong dependence on the federal centre and a focus on specific investors. Therefore, the eastern Russian regions are forced to build their economic policy, focusing on creating attractive conditions for large investors. The stability of economic growth can be ensured only through stable growth of the region population and improvement of the human capital quality. For the successful implementation of large-scale development plans for the east of Russia, it is necessary to stop the processes of depopulation of the territory and maintain optimal proportions between the economic and demographic reproduction.
Assessment of the soil cover in the Irkutsk Region by cadastral value
Authors: Sapozhnikov P M , Granina N I 
Published: January 2021

Abstract
The article defines the specific indicators of the soil cadastral value for the agroclimatic subzones of agricultural landscapes in the Irkutsk Region. We calculate the cost of the soils most common in the region, which are present in the scales of land classification and in the Unified State Register of Soil Resources of Russia. For the first time for the Irkutsk Region, we assess the quality of agricultural land rather by soil types, taking into account the area of a land plot, standard yield, and technological (standard) costs, than by soil differences. Soils in the land-assessment zones are represented according to the USSR soil classification system of 1977 and the international WRB system. Average values of the specific indicator of the cadastral cost of lands are within 0.1 RUB/m2 in typical sod podzolic soils (Albic Folic Luvisols (Cutanic, Different)); they reach 0.3 rubles/m2 in sod alluvial saturated layered soils (Mollic Fluvisols (Orthofluvic Amphifluvic)) and 3.1 rubles/km2 in leached chernozems (Umbric Calcic Luvic Phaeozems) as well as 3.3 rubles/m2 in meadow chernozems (Chernic Phaeozems (Endocalcic)) and in sod alluvial saturated soils (Mollic Fluvisols). Low indicators of the cadastral cost of agricultural land are due to low values of agroclimatic potential, low humus content in these soils and low thickness of humus horizon. We indicate the sensitivity of the method for calculating the cadastral cost of lands (2017) to different soils and geographical conditions.
Innovative entrepreneurship as a factor of the sustainable development in Irkutsk region
Authors: Klepikova T V 
Published: January 2021

Abstract
The introduction of high technologies in activities of small and medium-sized businesses is a priority task of sustainable development of Irkutsk region. The state is taking measures to support small and medium-sized businesses in the form of tax deferral, financial assistance and a number of benefits to enterprises in the spheres of activity most affected by the pandemic. Budgetary funding of scientific research of universities and other scientific organizations is a prerequisite for development of innovative products. Financial support of innovative technology parks, science cities, innovation centers for the transfer of improved technologies contributes to the introduction of practical modernized goods and/or services sold by small innovative enterprises. Young entrepreneurs between the age of 18 and 30 can receive grants for R&D or subsidies for development of technological production. Small innovative businesses are very risky, so applicants apply for grants from entrepreneurship support funds or investments in venture capital funds. In addition, entrepreneurs use modern innovative technologies to improve their knowledge and skills on the basis of online coworking, crowdfunding and crowdsourcing platforms. However, one of the main components of an innovative breakthrough is the system of education, research and development based on fundamental sciences. Sustainable development of small innovative enterprises is carried out through the creation of technology parks.
The resource-climatic potential of urbanized territories (a case study of the city of Irkutsk)
Authors: Korytny L M , Bashalkhanova L B , Maksyutova E V , Sorokovoi A A 
Published: January 2021

Abstract
A combination of average conditions for the diffusion of pollutants in the city of Irkutsk and significant volumes of emissions are the chief cause of a very high air pollution index during a long (longer than 20 years) period. In current conditions, the influence of the climate/atmosphere of the city of Irkutsk on the living conditions of the population implies an exceedance of hygiene standards in a year, on the average, for 5–6 pollutants. Furthermore, the composition and concentrations of pollutants are changing but the concentration of suspended material remains stably high (up to 2.4 MPC). Of particular concern is the largest exceedance of MPC for benzo(a)pyrene (up to 7.8 MPC), which is due primarily to a low quality of fuel used by mobile and stationary sources of emissions. The microclimatic characteristics of the city in the winter period were used to identify territories with a different temperature regime. The air temperature in low places is lower by 1.0–3.6 °C than at the Basic Irkutsk Observatory weather station. A large scatter in the deviations is caused by the warming influence of the Angara and by the infrastructural characteristics of the city. On the slopes and in elevated areas in the city center and outskirts, the temperature deviations do not exceed ± 0.5 –2.0 °C, respectively.

Published: January 2021

Abstract
The Olkhon region is one of the most popular holiday destinations on Lake Baikal, but spontaneous recreational development threatens the preservation of the region’s landscapes. The situation does not change even though a significant area of the Olkhon region belongs to the Baikal National Park, the uniqueness of the flora and fauna of which surpasses any other protected territory of the Baikal region. Geosystems studies were carried out on the southeastern macroslope of the Primorskii Ridge, in an area that stretches along the western shore of Lake Baikal for 50 km. Regional patterns, characteristics of climate and relief, differentiation of vegetation and soils, and features of the modern use of the territory were taken into account. At the same time take into account the regional patterns, characteristics of climate and terrain, vegetation and soil differentiation, especially of the modern use of the area. Construction and use of recreational facilities and the movement of vehicles is the main factor in an anthropogenic influence on the landscape of the study area. The landscapes of this site have a pronounced altitude-zonal structure. The goletz and mountain-taiga complex of the Primorskii Range alternates with the subtaiga steppe geosystems of the Preolkhon plateau. We carried out route surveys from the foot of the range to the mountains on four sites of the study area. These are the most interesting, popular places (routes) of the Olkhon region.
Analysis of slope stability of a segmental concrete block wall and geogrid in Meulaboh–Geumpang road
Authors: Yunita H , Chairullah B , Ambiya R 
Published: January 2021

Abstract
Landslide disasters are often a threat to the smooth transportation and economy of the community. Meulaboh-Geumpang crossroad, located in the western coastal region of Aceh Province, is one of the landslides-prone areas. Thus, the appropriate solution is necessary for preventing and handling the landslides in this area. This study conducted slope reinforcement using segmental concrete blocks combined with geogrids. The planned vertical distance of the geogrid (Sv) was 0.2 m, 0.4 m, and 0.6 m, while the length of the geogrid plan was 1 meter outside the failure envelope of the slip surface at the existing condition. The slope of the planned slope angle for the installation of the concrete blocks was 45°, 60°, and 90°. The dimensions of segmental concrete blocks were 20 cm high, 30 cm wide, and 40 cm long. The safety factor, at the condition after overall reinforcement, reached an acceptable amount for handling, only at STA 84 + 280 with a slope of 90°. A reinforced concrete beam was not added to the foot of segmental concrete blocks because it did not meet the acceptable safety factor, which was 1.32. The result of this analysis is to provide useful information about the form of a landslide that occurred. It will also inform the best combination of concrete block wall reinforced with geogrid for the reinforcement on the slopes. Thus, relevant parties can use it for landslide handling in these locations.

Abstract
The tsunami vertical evacuation buildings in Banda Aceh were built after tsunami in 2004. The buildings were intended as one of the mitigation strategies for the community that live in the tsunami prone zone area. The buildings should be designed as a robust structure that can resist the earthquake and tsunami impact. Previously, there were no national standard for the design of tsunami resistant structure. The state of damage buildings that had been considered was only based on the result of an earthquake impact, which include the ground shaking, soil failures, and surface fault ruptures. As the Standard in Indonesia did not cover the tsunami load, it is important to review the capability of the existing vertical evacuation in Banda Aceh. The study is aimed to explore the capability of the existing tsunami evacuation buildings as the vertical evacuation in Banda Aceh. The observation includes the tsunami load assessment of the buildings based on the existing standard that had been used internationally. The existing vertical evacuation buildings in this study is analysed for the performance based on the International standard (The Federal Emergency Management Agency FEMA P646 2012) for tsunami loading impact and the earthquake performance was based on the national standard (SNI 1726 2012). The model of the building structure was generated using software structural anaysis, i.e. SAP2000. The earthquake simulation was based on the 2004 earthquake scenario that input as the dynamic loading. The tsunami loading was analysed using the static analyse. The data of tsunami characteristic such as tsunami inundation and speed were using the data from the existing data and research. The results show that the building needs to be strengthening, as it will suffer the large inter-story displacement in the first and second floors.

Published: January 2021

Abstract
Banda Aceh has much revived and transformed into a better degree from the devastating tsunami disaster in 2004. Structural, infrastructure and social transformation have led to the economic growth of the city. One of the contributing factors to the growth is tourism. The number of tourists visiting Banda Aceh has increased progressively every year, with the most significant number coming from neighbouring countries such as Malaysia. To support the tourism development sector, Aceh needs a sufficient infrastructure, high-quality services and complete information about the disaster mitigation preparedness since most of the places of interest, namely the tsunami historical sites, are located in the tsunami-prone area. Lack of official information about the disaster mitigation preparedness becomes one of the critical issues that need to be provided by the government. This paper evaluates the readiness of Banda Aceh Government and its agencies in providing disaster mitigation information to tourists. Data was gathered from a series of interviews conducted with travel agents (tour guide) and Malaysian tourists in April 2019. This paper argues that in the emergence of special interest tourism called ‘disaster tourism’ or ‘dark tourism’ in Aceh’s tsunami-prone area, the availability of disaster mitigation guides or travel advice for tourists are still lacking and need urgent solutions. This paper addresses some practical recommendations for Banda Aceh Government to undertake the issues.

Published: January 2021

Abstract
The tsunami that occurred on December 26, 2004, devastated and damaged Aceh’s coastal area. Several months after the event, the Aceh peace agreement was signed between the Free Aceh Movement (Gerakan Aceh Merdeka, GAM) and the Government of Indonesia (GoI) in 2005. This study aims to analyze the integration of disaster risk reduction strategies within the 2005 Helsinki MoU agendas. By employing multi-dimensional perspectives, this study highlights the development process of the Aceh DRR strategies within the 2005 Aceh peace agreement agenda. The data was collected and analyzed by reviewing some of the relevant documents. This study also included interviews with the key persons involved during the conflict and DRR actors. The result shows that the disaster and the 2005 Helsinki MoU have brought Aceh to be more conducive in implementing development within important sectors such as infrastructure, spatial planning, education, and the environment and building initiatives at the community level, both formal and informal. It should be noted that the result indicates that DRR strategies had no direct relation to the strategic issues as implemented of the 2005 Helsinki MoU.

Study on Influencing Factors of Throat-like Residual Oil
Authors: Han Peihui 
Published: January 2021

Abstract
The microscopic visualization model is used to carry out oil displacement experiments, to test the interfacial tension of the ASP system, and to study the effect of different conditions on the throat-like residual oil by recording dynamic images of the residual oil during the displacement process. The results show that: when the concentration of polymer and alkali is unchanged, the higher the concentration of surfactant, the lower the interfacial tension of the ASP system; the water-wet attribute model is more conducive to the oil displacement system's use of residual oil. The lower the interfacial tension of the ASP system, the better the effect on the throat-like residual oil. when the interfacial tension reaches 10-2, the effect is obvious; after water flooding, the pore-throat ratio and the maximum diameter of the pores have little effect on the residual oil distribution. It has an effect on the residual oil distribution of the minimum diameter of the pores. After the ASP flooding, the large pore-to-throat ratio, the small minimum diameter, and the small maximum diameter have a greater impact on pores with different wettability.

Published: January 2021

Abstract
In order to study the influence of salt in the dustfall on the statue surface on the water migration in the earthen layer, this paper compared the relationship between the moisture content, electrical conductivity, and soluble salt content (Cl−, SO4
2−, K+ and Na+) with the sample height of the soil in the coarse-fine mud and the soil before-after desalination, after the migration of the simulated earthen test block under different relative humidity stabilizes. The result shows: When the dustfall salt migrate to the earthen layer, its salinity will migrate downward at the upper end of the test block; When the interaction between the dustfall salt and the water of the earthen layer, the electric conductivity and soluble salt content in the test block are increase with the increase of sample height, and quickly increase above the test block 6.7cm; The effect of coarse- fine mud layer on electrical conductivity and ion content is not significant, and the electric conductivity and soluble salt content in the test block containing salt were obviously higher than those in the desalted test block. Overall, the dustfall salt, as exotic salinity, plays a certain role in promoting the production of salt damage in the statue and promotes the ability of the water-salt transport in the earthen layer which will aggravate the corrosion of the statue surface.

Authors: He Xiucheng , Wang Yucai 
Published: January 2021

Abstract
The changes of soil ecological environment caused by different degrees of water deficit will affect the sustainable planting of soil, so it is of great significance to explore moderate water deficit and maintain a good ecological environment with sustainable soil. In this study, the effects of water stress on soil nutrients, microorganisms and enzyme activities of Isatis indigotica in Hexi corridor were studied by Mulched Drip Irrigation. The results showed that it was beneficial to the absorption and utilization of available phosphorus and available potassium in the soil of the root of Isatis indigotica by mild water deficit, increased the number of fungi and actinomycetes in the soil, and did not affect the activity of urease in the soil from 0 to 20cm. It was resulted in slow absorption of available phosphorus and available potassium in the soil and significantly decreased soil urease activity by severe water deficit, but it did not affect the number of fungi and actinomycetes. Therefore, mild water deficit is helpful to improve the utilization of soil nutrients and soil enzyme activity. This study provided a theoretical basis for the standardized planting of Isatis indigotica in northwest arid region on the basis of efficient water saving.
