Development of a mechanism for a comprehensive assessment of the state of agricultural landscapes and an interactive agroecological passport using a regional geoinformation system

The article presents the results of research carried out in 2015-2020 in the steppe and semi-desert landscapes of the southeastern part of the Stavropol region within the boundaries of the Sovetsky district, with the analysis and systematization of archival materials since 2000. The aim of the work is to develop a mechanism for a comprehensive assessment of the state of agricultural landscapes and an interactive agroecological passport containing information on the state of agricultural landscapes and their use using regional GIS. The author's methods and approaches used in the development of a comprehensive assessment mechanism, including the results of an inventory of lands, soils, dynamics of changes in agrochemical fertility indicators, the development of degradation processes, as well as an assessment of qualitative indicators of soils of agricultural lands with the development of a scheme for the use of land resources and an agroecological passport of the lands of the Sovetsky district of the Stavropol Territory on an agro-landscape basis, are presented. The mechanism of a comprehensive assessment of the state of agricultural landscapes has been tested, six agroecological groups of lands have been identified. The total area of arable land belonging to these groups is 165861 hectares. The results obtained are fundamental for the formation of a system of sustainable land use in agricultural landscapes: it is advisable to allocate 122831 hectares for field crop rotations, 27252 hectares for fodder crop rotations, 10547 hectares for soil-protective crop rotations, 4600 hectares are subject to change of purpose, 200 hectares are allocated for conservation and 431 hectares for reclamation construction. The research results are aimed at automating landscape and agricultural land typification, measures to reproduce soil fertility and improve land use efficiency, further implementation of "digital land use" and "smart field" systems, taking into account the agro-landscape approach.
