Correlation-regression analysis of ecological state of agricultural landscape of Precarpathians

Summary The aim of the given work is to establish empirical dependences of land erosion on the ratio and spatial distribution of land in agricultural landscapes of Precarpathians for ecological optimizing their structure. Methodology: calculations were carried out using correlation and regression analysis, and the dependence of eroded land on agricultural development; plowing and forest cover of Precarpathians region was quantified. This made it possible to build models of correlations that contain two-factor dependencies. Research results. Development factors and intensification of erosion in agro landscapes of Precarpathians are considered. The peculiarities of the water regime of the region’s soils have been studied. Quantitative and qualitative indicators of anthropogenic transformations of natural complexes are characterized. The extent to which modern land distribution does not meet environmentally sound standards has been assessed. The formation of water run-off according to the ratio of land area is explained. Indicators of the optimized structure of agro ecosystems of Precarpathians are calculated. These optimal ratios of land in Precarpathians should be taken into account when planning and taking into practice regional programs for the use and protection of agricultural landscapes in the region, the implementation of anti-erosion and natural-agricultural zoning of land.
