Abstract

Active development of the Cis-Ol’khon area in the past decades enhanced the conflicts between land users related to multifunctional land use (residential, agricultural, recreational, and nature-protective), which should be resolved on the basis of scientific data. The aim of this study is to compile a soil map of the coastal zone of the Ol’khon Plateau of 26.3 km² in area. This area is subjected to increasing recreational impact against the background of grazing and residential land use. Small-scale soil maps of this area show only the most general regularities of the geographical distribution of soils and do not reflect specific features of the soil cover. A digital soil map (on a scale of 1 : 25 000) of the area around the Kurkut Bay was compiled on the basis of the landscape-typological map by M.V. Zagorskaya and a network of 71 soil pits examined in 2015–2018). The classification of Russian soils of 2004 was used for the legend of the soil map; it was also correlated with the World Reference Base for Soil Resources (WRB-2014) system and the Classification and Diagnostics of Soils of the Soviet Union (1977), which was used in the soil map of the Elantsy state farm. Soil subtypes reflecting the entire range of soils in the studied area are the main taxonomic units in the legend for the soil map. Small and frequently alternating elementary soil areas in the studied region are formed under the impact of contrasting soil-forming factors. Lithozems (Leptosols) and gray-humus soils (Dystric Leptosols) occupy the main area. The analytical data and the soil map may be used as the basis for soil monitoring.

贝加尔湖地区Cis-Ol'khon地区的土壤覆盖

摘要

在过去的几十年中，Cis-Ol'khon地区的积极发展加剧了与多功能土地使用（住宅，农业，娱乐和自然保护）相关的土地使用者之间的冲突，应根据科学数据加以解决。这项研究的目的是编制26.3 km ²的Ol'khon高原沿海地区的土壤图在地区。在放牧和居住用地的背景下，该地区受到越来越多的娱乐影响。该区域的小型土壤图仅显示了土壤地理分布的最一般规律，并未反映出土壤覆盖的特定特征。根据MV Zagorskaya的景观类型图和2015-2018年检查的71个土坑网络，编制了库尔库特湾周围地区的数字土壤图（比例为1：25 000）。图例使用了2004年俄罗斯土壤的分类；它还与“世界土壤资源参考基准”系统（WRB-2014）以及在伊兰特州农场的土壤地图中使用的“苏联土壤分类和诊断”（1977）相关。反映研究区域内整个土壤范围的土壤亚型是土壤图例中的主要分类单位。在相反的土壤形成因素的影响下，在研究区域中形成了较小且经常交替的基本土壤区域。主要区域有石棉（细小溶胶）和灰腐殖质土壤（Dystric细小溶胶）。分析数据和土壤图可以用作土壤监测的基础。
