REMOTE-SENSING MONITORING OF SALINE SOILS

Results and techniques of remote sensing monitoring of saline soils in Eurasia are considered. The relationship between soil albedo in the v isible spectrum and soil salinity is described by functions of parabol ic form. More complicated are transfer functions permitting us to take into account photographic sensitivity, vegetation cover, and the infl uence of humus and moisture content. Spatial structure of saline-soil spotting is identified in aerial photos. Long-term monitoring of the a reas covered by saline soils makes it possible to estimate salinizatio n or desalinization processes in quantitative form for further control over their dynamics.
