СОВРЕМЕННЫЕ ЭКЗОГЕОДИНАМИЧЕСКИЕ РЕЖИМЫ РУССКОЙ РАВНИНЫ

Abstract

The geomorphologic regime of the platform plain may be subdivided into different types, which are determined by numerous processes and factors of morphogenesis including the morphological features of landforms. All processes and factors may be united into persistent characteristic complexes – exogeodynamic regimes of a plain. Using K-means technique of cluster analysis 8 regimes of the Russian Plain were distinguished: regime of erosion-frost dissection in the far North-East of the Plain, quasi-mountainous regime of its peripheral parts, regime of predominant karst denudation of humid and forested areas, and others. For this purpose 15 parameters were used including characteristics of some exogenous processes, and climatic, morphologic and tectonic factors. The subsequent hierarchical clustering of the regimes shows their interrelations. The spatial distribution and characteristics of the regimes are described, as well as their relation to morphosculpture of the territory.
