JUSTIFICATION OF THE DESIGN OF INFRASTRUCTURE ELEMENTS IN CONDITIONS OF DIFFICULT TERRAIN THE CENTRAL CHERNOZEM ZONE

Abstract

The relevance of the topic. The lack of specific recommendations on the design, assessment of the location of existing infrastructure elements and their operation indicates an insufficient amount of scientific research on this issue. This gap can be eliminated only on the basis of long-term field observations of the operation of forest strips, field roads, land boundaries, fields and their impact on the regulation of meltwater and stormwater runoff, as well as the actual development of erosion processes. Goal. Substantiation of the design of infrastructural elements - contour linear elements of the organization of arable land in the conditions of the complex relief of the Central Chernozem zone. Methodology. Monographic method, methods of comparative analysis. Results and conclusions. It is revealed that the system of infrastructural elements, such as the road network and protective forest strips, determines the main direction of soil treatment and the use of special anti-erosion agrotechnical measures. Only a scientifically based placement of linear elements of the territory organization will make it possible to more successfully address issues of surface runoff regulation by dividing large catchments into a network of artificial small ones and diverting residual runoff along the slope to safe places in the hydrographic network. Studies conducted on the distribution of arable land in small catchments, taking into account the shape of the slopes, have shown that the collecting (concave) shape of the slopes prevails on chernozems — 42.7 % of the total area of arable land. The ratio of arable land between expositions is of great importance for the design of anti-erosion measures. The data indicate that the northern slopes occupy 30.6 % of the concave slopes. There are significantly more washed-away soils on transversely scattering (convex) slopes, in contrast to transversely straight ones. Compared with neutral slopes, the intensity of soil washing on the southern slope increases by 1.05 times, and on the northern slope it decreases to 0.97. The contour organization of the territory involves the use of land, which takes into account not only the naturally formed configuration, but also the landscape structure of natural and anthropogenic complexes. This means that when developing ecological and landscape projects for the territorial organization of agricultural systems, infrastructure elements are placed - protective forest strips, field roads based on detailed consideration of the zonal factors of the Central Park, which will subsequently have a positive impact on the sustainability of the territory of agricultural organizations. When designing, it is necessary to take into account more fully the main factors that shape the processes of water erosion, such as exposure and slope shapes. The scope of application. The practice and economics of agricultural environmental management.
