Gorbatenko A. System analysis of agricultural landscapes of Forest-steppe of Ukraine on the basis of geoinformation environmental monitoring

The scientific problem of further improvement of the environmental assessment of agricultural land on the basis of theoretical generalizations, experimental and theoretical studies has been examined. It is established that the ecological role of biodiversity in agricultural landscapes is to ensure its sustainability by: the preservation and renewal of natural resources, self-regulation, self-cleaning and self-healing in biogeochemical cycles, optimization of the structure of land use types, renewal of energy and material balance, providing a reasonable occupancy of ecological niches in agronomic landscapes. Current approaches to system analysis of agronomic landscape are identified – integrated, ecosystem, landscape indicative index-indicative, selective. The scientific and methodological support ecological status of agronomic landscapes is analyzed, the indicators and parameters for diagnosis to avoid dubbing at the system analysis based on geographic information are systematized. Features of regulatory use of GIS technology in the study of the construction of specialized GIS National University of Life and Environmental Sciences of Ukraine «Agronomic Research Station» are specified. The absence of standards for regulating the development and use of HIT for the formation of geospatial information databases in the field of domestic technical regulations is defined. Methods for determining the average abundance of biodiversity to the level of the topical agricultural land are adapted. The index of natural resources potential of agricultural landscapes (1 to 10 points), which takes into account the environmental and agrochemical site quality score, erosion on the slope of the territory, the positive impact of agronomic belts, the index of abundance of biodiversity (natural-projected), the correction factors influencing factors, is developed and theoretically substantiated. A specialized «GIS agronomic experimental station of the National University of Life and Environmental Sciences of Ukraine» is developed for the assessment of ecological status, mapping and analysis of the system of agricultural landscapes: imaging evaluation of soil quality and integrated agro-ecological land evaluation, their environmental and technological grouping, determination of areas of positive agronomic effects of forest belts, analysis of spatial distribution of the indexes – abundance of biodiversity (natural-projected) and natural-resource potential of agricultural landscapes.
