AEROSPACE MONITORING OF LANDS DESERTIFICATION IN LEFT VOLGA BANK OF SARATOV REGION

Abstract

Desertification is a dynamic process in time and geographically. Monitoring is an essential component for monitoring, forecasting and early warning of desertification. Remote sensing data in agriculture are important for environmental control and monitoring. In this paper, by using the means of aerospace monitoring geobotanical indicators, we studied the development processes of aridization and desertification in the area of the Novouzenskiy district Saratov region, the impact on them of climate change and anthropogenic load on ecosystems. Were identified areas with intense desertification, meter charts of bioproduct activity of land remote sensing data for 1986, 1989 and 2015, and also the rate of degradation of vegetation cover due to the progression of desertification, which is 1807 hectares per year. Overall, the use of the arid lands and resource-saving technologies, the device of forest-agrarian ecosystems and implementation on arable lands of adaptive crop rotations with a large share in their composition of perennial grasses will provide adequate protection of soils from further degradation and desertification of the area.
