We analyzed: 1) morphometric characteristics of the terrain: density of dissection (km/km2), depth of dissection (m/km2), General dissection of the terrain (km/km2), obtained by multi-stage processing of data from The earth's radar survey (SRTM). Overlay analysis of the following maps was performed: maps of the density of the terrain division, maps of the depth of the terrain division, and maps of the General terrain division. A geo-information model of potentially dangerous areas of origin and development of erosion processes was created based on the overlay of zones of the highest values of terrain dissection. The resulting map was created by interpreting the results of overlay operations and defining extreme values for each parameter. The graphic constructions obtained from a set of morphometric indicators will be of great applied value when planning the construction of new socio-economic objects, when developing General schemes for expanding existing settlements and designing new ones, when planning the construction of linear objects, as well as when developing measures for the engineering protection of territories, buildings and structures. Были проанализированы: 1) морфометрические характеристики рельефа: густота расчленения (км/км2), глубина расчленения (м/км2), общее расчленение рельефа (км/км2), полученные путем многоступенчатой обработки данных радиолокационной радарной съемки Земли (SRTM). Осуществлен оверлейный анализ следующих карт: карты густоты расчленения рельефа, карты глубины расчленения рельефа и карты общего расчленения рельефа. На основании наложения зон наиболее высоких значений расчлененности рельефа была создана геоинформационная модель потенциально-опасных участков зарождения и развития эрозионных процессов. Создание результирующей карты выполнялось путем интерпретации результатов оверлейных операций и определения экстремальных значений по каждому параметру. Полученные по комплексу морфометрических показателей графические построения будут иметь большое прикладное значение при планировании строительства новых социально-экономических объектов, при разработке генеральных схем расширения существующих населенных пунктов и проектировании новых, планировании строительства линейных объектов, а также при разработке мероприятий инженерной защиты территорий, зданий и сооружений.

Engineering Protection

During the construction of roads in mountainous areas, engineering protection of the highway from landslide processes is often required. Currently, there are many designs used to protect against landslides. However, the engineers are faced with the task of choosing the optimal structural solution both in terms of the boundaries of the field of application of the structures and in terms of economic efficiency. In addition, the problem arises of correct modeling of the predicted situation. The article discusses the engineering protection of the road under construction in Sochi, Krasnodar Territory. In the study of the territory on the site, three landslides were found that are in extreme condition, erosion processes, an elevated level of groundwater, planar flushing, and also weathering of bedrock when they are opened during the laying of the route. Two schemes of constructive solutions using gabion construction both on a natural basis and on a pile are considered. The choice of the type of protective structure is determined by the presence of both surface and ground waters, as well as by a technical and economic comparison (in comparison with a reinforced concrete retaining wall). The authors reviewed existing software systems used in the calculation of underground structures, and also analyzed the basic methods for calculating the slope stability and structural strength. As a result of the study, such geotechnical software systems as: Plaxis, GeoStudio, Geo5 were selected to simulate a landslide slope. Slope stability was determined both for the main combination of loads and for the special one (seismic of 8 points) using such methods as: Phi/c reduction, Morgenstern-Price method and Shahunyants method. The results obtained showed good convergence.

Vineyard Soil

Land degradation, especially soil erosion, is a societal issue that affects vineyards worldwide, but there are no current investigations that inform specifically about soil erosion rates in Chinese vineyards. In this review, we analyze this problem and the need to avoid irreversible damage to soil and their use from a regional point of view. Information about soil erosion in vineyards has often failed to reach farmers, and we can affirm that to this time, soil erosion in Chinese vineyards has been more of a scientific hypothesis than an agronomic or environmental concern. Two hypotheses can be presented to justify this review: (i) there are no official and scientific investigations on vineyard soil erosion in China as the main topic, and it may be understood that stakeholders do not care about this or (ii) there is a significant lack of information and motivation among farmers, policymakers and wineries concerning the consequences of soil erosion. Therefore, this review proposes a plan to study vineyard soil erosion processes for the first time in China and develop a structured scientific proposal considering different techniques and strategies. To achieve these goals, we present a plan considering previous research on other viticultural regions. We hypothesize that the results of a project from a regional geographic point of view would provide the necessary scientific support to facilitate deriving guidelines for sustainable vineyard development in China. We concluded that after completing this review, we cannot affirm why vine plantations have not received the same attention as other crops or land uses.
