Abstract (AI)
The article discusses the issue of application geographic information systems for inventory agricultural land and assessment of their condition. A geoinformation project has been developed for conducting geoecological appraisals agricultural land of the Altai region of the Republic of Khakassia. The structure of agricultural land, the area determined fallow lands and an inventory of forest belts investigated territory has been studied based on analysis of the agricultural map of scale 1: 100,000, interpretation of Landsat 4-5, 7, 8 and Sentinel 1 and 2 images, and also ground based satellite research. To processes overgrowth tree and shrub vegetation the deposits subject were revealed. The research results showed that on the study area in the structure of agricultural lands 56860 hectares of land belong to the deposits located on different stages of recovery. The elm overgrowing processes covered about 28580 hectares of post-agrogenic lands.
