Territorial assessment of regional factors erosions of agricultural land Amur region |

Soil erosion is one of the most intensive processes of relief formation. In the Amur Region, on the area of cultivated land, 1514.2 thousand hectares with an average washdown rate of 4.1 tons per hectare per year, erosion-hazardous lands accounted for 35.7%, and eroded - 7.3%. In this article, based on the data of the state land registration, special surveys and monitoring, cartographic stock materials of the Territorial Fund of Information on Natural Resources and Environmental Protection of the Ministry of Natural Resources of Russia for the Amur Region and the materials of its own research, the combined effect of a subset of natural and anthropogenic factors, danger of manifestation and development of water and wind erosion in the Amur region. Scientific analysis of the dynamics, scales and conditions of the erosion processes is of great scientific and practical importance and is the basis for the development of a system of anti-erosion measures that could slow down or stop the development of erosion processes when investing minimal cash.
