CARTOMETRIC AND MORPHOMETRIC INDICATORS AS A BASIS FOR DETERMINATION OF NATURAL PREREQUISITES FOR THE DEVELOPMENT OF EXOGENOUS GEOMORPHOLOGIC PROCESSES ON THE TERRITORY OF THE BELGOROD REGION

Гайворонская Н.И.
On the basis of topographic maps of Belgorod region scale 1:200000, a series of morphometric maps (vertical and horizontal dismemberment of the earth’s surface, steepness and the exposition of the slopes, orders erosion network and others) was worked up, which allowed to obtain quantitative indicators of the relief of the Belgorod region. These indicators determine the main natural prerequisites for the development of exogenous geomorphologic processes, intensity of which reflect the degree of tension of ecological-geomorphologic situation in the Belgorod region. For research saturation erosive forms of a different order in the Belgorod region, a map of the orders of magnitude of erosion forms was worked up, it makes possible to reveal erosion forms of different genetic variations. This map was the basis for morphometric map of horizontal dismemberment of relief. The map of horizontal dismemberment gives a graphic representation of the infestation of the territory of Belgorod erosion processes, allows to establish the quantitative characteristics of morphometric parameters of a relief, to reveal its potential for the development of exogenous geological processes. Significant vertical dismemberment contributes to the increase of aggressiveness of erosion processes. Depth dissection of relief within the region varies in the range of 20-110 m. the Highest indicators differs the Eastern part of the region, which can be attributed to the zone of risk.
