Ecological-economic evaluation of agricultural land in Samara region on the example of Bor district

The zones of ecological trouble cover about 15% of the territory of Russia, where the main production capacities and the most productive agricultural lands are concentrated. The Samara region is characterized by a distinct natural zonality from a typical forest-steppe in the North with a forest cover close to 30%, to an open dry steppe in the South with a natural forest cover of only 0.1...0.2%. The article presents an analysis of land use in the Samara region on the example of the Borsky municipal district. Research methods include environmental analysis and statistical data analysis. The relief of the territory of the Bor municipal district is hilly and bumpy. A wide undulating plateau watersheds transform into flat and sloping slopes. The southern slopes to the rivers Samara and Kutuluk sloping, sometimes steep, rugged ravines and beams. The Northern slopes are flat, long, gradually turning into floodplain terraces and floodplains. In General, the relief of the district is relatively leveled. In the soil cover of the district located North of the river. Kutuluk, is dominated by typical chernozems, less common leached chernozems, typical carbonate and typical residual carbonate. Analysis of the qualitative state of land in the Borsky district, showed a decrease in fertility, large areas of land subject to degradation processes, the increase in the area of anthropogenically altered soils, indicates the need for certain land management measures to improve the condition and raise the level of land use. The article presents an analysis of the land use of the Borskiy municipal district. During zoning, the territory of the district is divided into the northern, central and southern parts. Assessment of environmental and economic parameters showed heterogeneity of the territory and the need for detailed consideration of climatic, soil, economic conditions in the design of landscape optimization systems, even in the municipal area. In general, the district›s land fund experiences an average anthropogenic load, the ecological stability of the territory as a whole is characterized as unstable stable. In comparison with other areas of the Central MES, the municipal Borskiy district belongs to the category with an average ecological intensity with a stabilization index of 0.59 units due to the beneficial influence of the Buzuluksky area.
