Abstract
At present exist several approaches to classification of characteristics (classes) estimation of ecosystem and geosphere cover of the Earth. At norm-setting and standardizations of man-caused influence to environment it is offered to choose the biotic factors, that itself comprise to three classes of the factors: thematic, spatial and dynamic. The thematic factors includes botanical (geobotanical and biochemical), zoological and soil factors. This factors allows, with an exclusion of biochemical factors, characterize resources potential of analyzed component, and through it the ecosystem conditions.
