SPATIAL ANALYSIS OF FOREST SOIL-PROTECTING PLANTATIONS OF AGROLANDSCAPES BY REMOTE METHODS
Forest shelter belts are the main element of agroforestry and used as an important anti-erosion measure. The Trynovsky district of the Stavropol Region used as the study area. Area of arable land in the Trynovsky district according to the data of remote sensing of the Earth in 2018 was 128953 hectares or 77% of the district area. The total length of linear water erosion on the arable land of Trynovsky district is 450 km. This type of degradation damaged 36% of the Trynovsky district arable land. Using Earth remote sensing data and geo-information technologies, forest shelter belts were identified, with a total length of 2,453 km and an area of 6,670 hectares. Protective forest cover of the district is 5.2%. The spatial orientation analysis of the forest shelter belts showed that 73% of them are perpendicular to prevailing winds. An analysis of the forest shelter belts position relative to runoff lines showed that in Trynovsky district only 13% of forest shelter belts could protect arable land from water erosion. As a result, it was established that the forest shelter belts in the Trynovsky district are designed to protect the soil from wind erosion. Studies have shown the effectiveness of using modern geographic information technologies and Earth remote sensing data for spatial analysis of forest shelter belts. The results can be used to model new anti-erosion boundaries and adjust existing ones taking into account regional characteristics of climate change, agricultural development of the territory and the current state of anti-erosion boundaries.
