Mapping of the territory by the LS erosion factor using a geoinformation system and a digital terrain model

It is noted that the problem of protecting soils from erosion is becoming more and more urgent every year. This is due, firstly, to the awareness of the outstanding role of soil in the life of the biosphere, and secondly, it is due to the fact that the soil cover is now in critical condition. Soil erosion has become one of the most significant environmental problems in the world. Quantitative assessment of erosion parameters is an important scientific and practical task. The article examines an example of mapping the territory by the LS-factor of erosion using a geographic information system and a digital relief model. The total LS-factor range was 0...118. The highest specific gravity (73.3%) is LS = 1 (in the territory of 126691.58 hectares with an average area of a single plot of 43.61 ± 8.44 hec-tares). It is noted that not only large changes in the shape of the relief, but also small ones have an impact on the nature of erosion. This feature is manifested in the fact that in some areas there is a flush, and in others – the accumulation of soil erosion products. This explains the characteristic fluctuation of the LS-factor on the map.
