Summary. On the basis of conducted researches, results of authers’ experience and data of scientific literature using systematic analysis, modern techniques, and GIS technologies the structure of the database of agro-ecological assessment of land in agro-landscapes was created. The investigations were carried out in the laboratory of geoinformation systems and agro-ecological monitoring of Russian Research Institute of Agriculture and Soil Erosion Control in 2013-2015. The structure of the database includes 5 modules: general information, agro-climatic resources, relief and geological structure of the area, soil resources, biological resources. General information includes 5 positions, agro-climatic resources–15, relief and geological structure of the area–7, soil resources–16, biological resources–3 positions. It reflects the necessary details about agro-ecological assessment of agricultural landscapes in the form of a strictly ordered structure, but with the possibility of its development and dynamics. The key component of the structure is a plot of land with defined boundaries, part of agro-landscape basis. Database objects include tables for storing information, queries, forms and macros. Created database structure provides the possibility of making an electronic database in DBMS Access and creating software of agro-ecological land evaluation based on GIS technologies. There are presented the electronic maps for agro-ecological land evaluation of APC «Rus’» of Soviet district of Kursk region on the content of humus, alkali hydrolysis nitrogen, mobile phosphorus, exchangee potassium and acidity (pH) in the arable layer of soil. The proposed structure of the database of agro-ecological land evaluation is necessary for the automated design of adaptive-landscape farming systems.
Keywords: agroecological assessment, database, parameters, soil properties, location in the landscape, adaptive-landscape farming systems, GIS technologies.
