NATURAL RECOVERY OF PHYTOCENOSES IN THE CONDITIONS OF NATURAL AND TECHNICAL SYSTEMS OF THE SOUTH OF THE FAR EAST

Abstract

The paper desсribes the features of formation of secondary phytocenoses on technogenic landscapes. The authors have estimated the area characteristics of natural recovery of phytocenosis. It is revealed that in the natural and technical system of the objects studied the structure and intensity of vegetation restoration processes are determined mainly by species diversity and stability synusia of phytocenosis of the contiguous ecosystem. The authors have analyzed the normalized difference vegetation index (NDVI) data for test objects and considered its dependence to natural and anthropogenic parameters. The authors have established the criteria determining the quality and speed of development of secondary phytocenoses in the disturbed territories. It is established that the process of self-recovery of natural biota after the completion of mining operations, the closure of the enterprise and the realization of a reasonable minimum of recultivation measures will be determined by the regenerative resources of the biota outside the zone of its technogenic damage, the size of the zone and the climatic characteristics of the region.
