The Ecological—Geological System, Its Types and Position in the Structure of an Ecosystem

摘要

An ecologic–geological system presents a certain volume of the lithosphere with biota, including mumans and the social media functioning in it and on its surface. This system is considered as the study subject of ecological geology. In all, four types of ecological–geological systems have been distinguished and charac-erized: a natural real system, natural ideal system, natural–technical ideal system, and natural–technical real system. The position of an ecological–geological system in the structure of an ecosystem is shown.
