Ecological aspect of the development of soil-forming processes at the post-technogenic stage

The relevance of the study is caused by the problem of the global anthropogenic transformation of natural landscapes in Kuzbass as a result of the development of mining. The rate of reclamation of disturbed lands lags behind the rate and scale of their formation, and most of the territory is self-recovering. This paper is aimed at studying the ecological conditions of the natural environment and technogenic factors affecting the dynamics of soil-forming processes and the formation of phytocenoses in disturbed territories, which differ in the way of formation at the technogenic stage. For the first time, some physicochemical parameters of technozems were obtained. Like ebriozems, they are formed in the post-technogenic phase of the development of a technogenic landscape under the conditions of its self-growth. The similarities and differences in the properties of technozems and ebriozems formed in the same natural and climatic conditions of the southern forest-steppe zone of Kuzbass have been revealed. It was found that the rate of their transformation, expressed in the formation of the soil profile, depends on the conditions of the relief and underlying rocks created at the technogenic stage. The presence of a preserved layer of potentially fertile rocks and the absence of slope surfaces led to the formation of the frontal soil and vegetation cover of the technozem; under other conditions, the formation of soils and plant groups occurs fragmentarily, which leads to the asynchronous development of the functions and modes of the technogenic landscape.
