Abstract

Areas of coal mining dumps naturally overgrowing with vegetation in the dry-steppe (Khakassia), forest-steppe (Krasnoyarsk Krai, Kansk-Achinsk Fuel and Energy Complex, KAFEC) and subtaiga (Kemerovo region, Kuzbass) subzones were investigated. The environmental and cenotic characteristics of herbaceous communities were studied in experimental sites following the application of a fertile soil layer and in technogenic eluviums without soil improvers. The application of a fertile soil layer was found to increase both the species abundance and the projective cover of zonal species. Thus, the presence of a humus horizon promotes the formation of herbaceous ecosystems. However, this is not an unconditional factor that these ecosystems would reach the stage of zonal formations.

The restoration of plant communities on postindustrial lands is one of the most important factors in the involvement of technogenic substrates in the biological cycle
Various recultivation techniques are currently used to increase the similarity of technogenic ecosystems to natural ecosystems [2]
The rate of ecosystem restoration largely depends on the restoration of soil and environmental functions, which, in turn, depends on the natural and climatic conditions of the territory where the technogenic objects are located

Summary

Introduction

The restoration of plant communities on postindustrial lands is one of the most important factors in the involvement of technogenic substrates in the biological cycle. Various recultivation techniques are currently used to increase the similarity of technogenic ecosystems to natural ecosystems [2]. The rate of ecosystem restoration largely depends on the restoration of soil and environmental functions, which, in turn, depends on the natural and climatic conditions of the territory where the technogenic objects are located. We analyse restoration processes in the plant communities of embryozems and technozems formed on rock dumps produced by coal mines in various climatic and edaphic conditions
