Development of ecosystem principles for optimising differentiated land use management

The article presents the results of the analysis of the main trends in the ecological and geochemical transformation of the environment of Southern Russia. The research on revealing the regularities of migration and distribution of elements in soils of landscapes testifies to the necessity of changing the basis of management. This includes introduction of ecosystem principles of management of nature use and environmental quality, timely adjustment of economic mechanisms and resource cycles. The methodology of the ecosystem ecological rationing of chemical elements in soils for optimisation of differentiated land use management has been developed. The system of measures to ensure environmental safety in the region is proposed. It includes identification of pollution and assessment of sources of environmental hazards, maintenance of environmental passports of land plots, measures to protect the environment in the process of economic activity, measures to prevent and eliminate natural and man-made emergencies associated with environmental pollution.
