This paper deals with soil and vegetation diversity and structure of the cover. Ecological rows and ecosystem com-plexes connected with relief are described. A generalized scheme of ecological ordination by moisture and soil fertility was build based on ecological scales. Habitat assessment by vegetation was proved by the soil analysis.Key words: vegetation, spatial structure, steppe zone, Lake Kulunda.
