Abstract

The main stages of using the basin concept using the method of relief plasticity in the rational use of water and land
resources of irrigated lands of the modern Amu Darya Delta are considered in this article. It is shown that reservoir basins are
the most widespread geosystems of a high degree of functional integrity within the irrigated lands, with clear boundariesriverbed
shafts, having a powerful integrating factor-a system-forming water flow. The ideas about the reservoir basin as a
geosystem, about the internal structures of the basin in the form of unidirectional relief elements: increases and decreases are
substantiated. The modern delta of the Amu Darya is differentiated for the first time into reservoir basins that have the
qualities of geometric and physical similarity. The role of the structure of the idealized reservoir basin in the reclamation
assessment of irrigated lands is revealed; it is established that it consists of small deltas of different ages and they are the basis
for nature management. It is proved that the integrating properties of the system-forming water flow allow us to consider the
reservoir basin as an integral system formation from the standpoint of not only meliorative geography, but also geochemistry,
as well as in complex physical geography – as functionally integral natural complexes, thereby creating a natural basis for
nature management. At the same time, the reservoir basins of irrigated lands of delta geosystems are natural and economic
systems. It is proposed to apply large-scale basin mapping - the method of relief plasticity in the study of natural and economic
systems of territories in relation to the features of the structure of reservoir basins.
