Эволюция выработанного рельефа и аналитическая легенда геоморфологической карты

Аннотация

The paper discusses the classification of surfaces of destructive landforms as objects of mapping. The evolution principle of the systematization based on classic theory of landscape stadial development is suggested. The dissection and planation surfaces make two general classes corresponding to the ascending and descending phases of the cycle of erosion. The intermediate subclass of the planation-dissection surfaces is considered to form during the stage of late maturity. The further division of surfaces is executed after initial surface-forming processes. Thus the dissection surfaces may be tectonic, fluvial, marine-abrasional etc. The planation surfaces of the last stages of the cycle make only one genetic type of «denudational surfaces». The genetically various surfaces of two evolution classes are pictured in two different sets of colors. Numerical or verbal nomenclature of local cycles of erosion is proposed for indication of the relative age of the surfaces.
