Геоинформационное обеспечение оценки эрозионной опасности земель сельских территорий

Abstract

The problem of timely and accurate assessment of the erosion hazard of the territory is quite acute for the agro-industrial complex of our country, since erosion processes cause great damage to agriculture. To ensure the work on the rational organization of the territory and competent land management support for these actions, it is necessary to use modern technologies and modern software in the field of geographic information systems. Thanks to geographic information systems, it becomes possible to quickly and efficiently create sufficiently accurate and informative planning and cartographic material necessary for the development and implementation of projects for the anti-erosion organization of the territory. This paper describes the main indicators of the erosion hazard of land, shows the methodology for their calculation using geographic information systems on the example of agricultural producers of the Okhansky District of the Perm region. In the course of the work, cartographic images of the study area, soil features of the study area, reclassification of the raster of soils and parent rocks, relief of the study area, slope slopes and reclassification of the slope raster, exposure of slopes and reclassification of the slope exposure raster, allocation of cultivated lands, image of types of land use and raster reclassification using types, distribution of the LS factor on the territory and reclassification of the LS factor raster, image of the erosion potential of the territory. The use of the developed planning and cartographic material will greatly facilitate the information support of the process of land management and anti-erosion organization of the territory. It is recommended to use data on the erosion hazard potential of lands in the development of municipal program documents in the field of rural development in the Okhansky District. The standards developed for agricultural enterprises can be used in municipal programs for the development of the industry, in the process of planning and organizing agricultural production.
