【 摘 要 】

Species composition and specific ecological structure of oribatid mites community in industrial site and buffer zone of «Artyomovsk nonferrous metal plant» and botanical nature sanctuary «Steppe Otradovskaya» were established. The ecological structure of «Artyomovsk nonferrous metal plant» area is perturbed, and typical for the anthropogenically-transformed ecosystems, and has low rates of average population density, wealth rate, ecological diversity indexes; it also has changed in dominance structure and life forms distribution. The oribatid community structure in the botanical nature sanctuary «Steppe Otradovskaya» during the spring period is typical for Donbass steppe conservations. In summer it resembles structurally in disrupted landscapes due to adverse edaphic conditions, occurring in Donbass in August. The integral sensitivity threshold indicator for oribatid mite communities shows that an environmental state of the technogenic area («Artyomovsk nonferrous metal plant») in summer and autumn is subnormal. The ecological status of «Steppe Otradovskaya» in spring can be considered as normal, and in the thalweg of the steppe gully as relatively favorable. During summer, the environmental condition of the study area is subnormal.Key words: oribatid mites, community ecological structure, bioindication.
