Experience in creating a soil-reclamation map of the Zarafshan river valley based on the system analysis of lithodynamic flow structures

Analysis of lithodynamic flows and soil-reclamation studies, based on the plastic relief map, allowed for a systematic analysis main components natural environment. The ways migration chemical elements in soil are established. For first time, causal relationships spatial differentiation degree composition saline soils Zarafshan river valley were revealed. basin has clearly defined border, as we can judge from map made up 1: 100 000 scale. Here three cascade systems well distinguished, which is very important formation reclamation state territory. In this area, that is, subsystem, proluvial-alluvial deposits volume groundwater, closely related to surface. This subsystem part catchment area basin, source removal territory huge mass dissolved solid substances.
