Abstract

Starting from 2006, the active development of the Aibga Ridge slopes in the vicinity of the resort township of Krasnaya Polyana and construction of sports and tourist facilities in that area have changed the land use type; as a result, exogenous processes, primarily mudflows, have intensified, posing risks to the engineering facilities and human safety. Based on remote sensing data (high-resolution satellite images, orthoaerial imagery, and digital elevation models produced on their basis), an inventory of the main types of anthropogenic disturbances and manifestations of exogenous processes was performed for 2006 and 2019 in a number of hierarchically subordinate test areas: a 25-km² polygon, the Sulimovskii creek basin (6.9 km²), and a key site in the Chernyi creek (a right tributary of the Sulimovskii creek) catchment basin (0.8 km²) whose upper reaches approach engineering facilities of the Rosa Khutor ski resort. Comparative analysis made it possible to assess the conjugate spatial development of anthropogenic forms and natural processes. In 2006–2019, the area of anthropogenically transformed lands increased by more than five times on average reaching 25–30% (in some catchment basins, up to 50%). Concurrently, the total area of sites affected by exogenous processes has increased both qualitatively (more types of processes) and quantitatively (by more than seven times on average) reaching 0.8% of the test polygon area (in some catchment basins, up to 4%). The anthropogenically-induced land use changes doubled the surface runoff causing a sharp intensification of erosion, landslide, and other conjugate slope runoff processes; as a result, the frequency of mud floods increased.

2006-2019 年 Aibga 山脊斜坡（西高加索）泥流强化因子的定量评估

摘要

从2006年开始，喀斯拉雅波利亚纳度假小镇附近艾布加岭斜坡的积极开发以及该地区体育和旅游设施的建设，改变了土地利用类型；因此，外源过程，主要是泥石流，加剧了，对工程设施和人类安全构成了风险。基于遥感数据（高分辨率卫星图像、正射影像和基于其产生的数字高程模型），对2006年和2019年的主要人为干扰类型和外生过程的表现形式进行了多个层次的清查。从属试验区：一个 25 公里^{2 的}多边形，Sulimovskii 溪流域（6.9 公里²)，以及 Chernyi 小河 (Sulimovskii 小河的右支流) 流域盆地 (0.8 km ²) 其上游接近 Rosa Khutor 滑雪胜地的工程设施。比较分析使评估人为形式和自然过程的共轭空间发展成为可能。2006-2019 年，人为改造土地面积平均增加了 5 倍以上，达到 25-30%（在一些流域，高达 50%）。同时，受外源过程影响的场地总面积在质量上（更多类型的过程）和数量上（平均增加了七倍以上）达到了测试多边形面积的 0.8%（在一些集水盆地中，高达 4%） ）。人为引起的土地利用变化使地表径流增加了一倍，导致侵蚀、滑坡和其他共轭斜坡径流过程急剧加剧；其结果，
