Abstract:
It was shown the results of a study of the geomatic factors in the formation of geosystems in the
Sarysu river basin. Within the framework of the basin under consideration are the subgeosystems of upper-Sarysu,
middle-Sarysu and lower-Sarysu, where the spatio-temporal relationships of the channel-forming processes from the
source to the mouth of the river dominate. The basic factors of the formation and functioning of modern isolated
subgeosystems of the basin under consideration are revealed.
On the map we compiled on the scale of 1: 500 000 modern exodynamic processes of the basin under consideration, classes of exogenous natural geosystems and classes of exogenous anthropogenic and technogenic
geosystems are differentiated, requiring different approaches in developing the optimal structure of the nature use of
the Sarysu river basin. When considering modern geodynamic processes, the main factors of anthropogenic activity
are identified, which are the most powerful factor of self-organization and dynamics of geosystems.
As a result of revealing the natural and climatic features of the development of modern geodynamic processes
of pollution of geosystems in the conditions of intensive anthropogenic activity, the growing aridity of the climate
and anthropogenic load within the Sarysu river basin contribute to the intensification of arid denudation processes,
leads to a sharp activation of water-wind erosion and the expansion of lands subject to a planar washing, spoiling,
deflation and other processes.
