Components of Anthropogenically Transformed Landscapes of South of Russia Interaction

Abstract

The objects of the study were the southern dry steppe and agricultural objects located within it with a spatial combination of agrobiocenosis and elements of anthropogenic impact on the territory of South of Russia. As a result of the research it was found that the intrusion impact on agrobiocenosis is comprehensive and mainly negative. Intrusion with projective cover (PC) less than 50% to a small extent affects the adjacent agrocenosis, when covering 70% or moreleads to quite pronounced changes in the adjacent areas of the agrocenosis. It also influences to the trophic structure of ecosystem and the nature of the links between its components. The creation of a stable "core" community consisting of productive perennial plants adapted to the conditions of the southern dry steppe is a general trend of plant interaction in the studied phytocenoses. A design of the database for information storage and systematization on the basis of the consort relationships between the main participants of biogeocenoses was developed. In future, it will allow to build a prognostic model for faster and more reliable screening of impacts on natural communities within the necessary environmental measures' framework.
