Изучение планового рисунка речной сети при морфоструктурном анализе

Аннотация

A cartographic analysis of drainage pattern allows to get quick information on main morphostructures of the region under study. Conceptions of «drainage pattern» (geometrical scheme of network formed by streams) and «stream distribution» (distribution of drainage directions) are defined, the two main properties jointly characterize type of drainage net. The methods of analysis include the territory regionalization according to types of drainage net, some additional properties of the net being used; the materials obtained are interpreted from the point of view of morphostructures. Morphostructural regionalization of the North-East Asia on the base of drainage pattern analysis is considered as a case study.
