ABSTRACT

Mapping of the agrolandscape survey site within the boundaries of Frolovsky district of the Volgograd region is aimed at determining its geomorphometric characteristics, specifying the area and boundaries, as well as assessing environmental stability and integrity. The agrolandscape studied is agricultural with an area of plowing more than 70%, and the share of forest strips is minimal, accounting for 1,8%. A quarter of the agrolandscape is covered by the slopes and the beams which amount to 25%. Based on the digital relief model, the geographic coordinates of the analyzed polygon were obtained, and the maximum and minimal elevations and exposure of slopes were determined. The boundaries of 20 arable land plots with a total area of 2070,88 hectares were specified. The main types of the slopes are highlighted: flat surfaces (steepness up to 1^o) – 30,0%; very gentle (steepness 1-2^o) – 55,0%; gentle (steepness 2-3^o) – 15.0%. The stability of the agrolandscape was assessed by a number of indicators. Low degree of protection by forest plantations (K_{field-protective forestation} = 2,5), high degree of area ploughing (K _{index of ploughing} = 72,8), lack of species diversity of agroecosystem (J_p = 3,9), increased roughness and articulation by beams and ravines (K_articulation = 0,38) indicate that this agrolandscape is ecologically unstable (K_{ecological stability} = 0,14). All these factors result in decreasing the ability of the agrolandscape to reproduce, to self-preserve and to restore the potential of soil productivity. The novelty of the research lies in the creation of a local geoinformation system of regional agro-landscape complexes and the identification of priority areas for agricultural production.
