Structural and morphological organization of dry valley of the Cretaceous south of the Central Chernozem Region

Abstract

The peculiarities of origin, morphological and genetic varieties and structural and dynamic interrelations of dry valley landscapes of the Cretaceous south of the Central Chernozem Region are considered. Modern ideas about genesis, morphology, development and landscape structure of sukhodols are presented. Paradynamic interrelations of structural elements of basin landscape systems are emphasized. The necessity of taking into account landscape specificity of dry lands when solving the problems of nature management and optimization of landscape-ecological situation in the Cretaceous south of the Central Chernozem Region is emphasized. As an example, we analyzed the component, territorial and altitudinal organization of natural complexes of a large sukhodols of the Kuvshin dry valley located in the Podgorensky district of the Voronezh Region. The main factors of landscape differentiation are established, among which are peculiarities of morpholithogenic base, character of biostrom development, modern economic use. The problems of identification of local landscape boundaries and approaches to their solution have been noted. Based on the results of the research, 7 families and 45 species of landtypes, as well as altitudinal landscape layers and sub-layers were identified within the valley. Recommendations on changing the conservation status of the territory are given.
