ABSTRACT: The article gives the results of long-term researches regarding the processes of desertification of droughty European grounds – Russian Caspian areas. The fact that the authors consider desertification as unification, which leads to degradation of all arid ecosystems components, makes the approach particular. It was determined that the eco-dynamic species of vegetation subclass had the largest indicator value enabling to trace sequence of degradation, allocate the criteria of the evaluation, and stages (classes) of desertification. They make the main content of biological conception of desertification developed by the authors. Cartographic materials prove convertibility of this process in the conditions of semiarid zone of European continent under influence of natural and natural-anthropogenic factors.

KEYWORDS: desertification; drylands; evaluation criteria; unification; biological concept; degradation; vegetation; indicator; pasture degradation; redesertification
