Dolina O. Edaphotopes and plant communities in industrial landscapes of Kryvbas: spatial structure and characteristics of the formation

The work is devoted to the study of the spatial structure and characteristics of plant communities and edaphotopes in industrial landscapes of Krivbass. The degree of soil cover transformation under the influence technogenesis was studied. Determined that the share of natural soil in the region is currently only 34.5%; technogenic soils formed occupy 451.72 km2 (5.6% of the area). Aggregate composition, humus content of soluble salts in edaphotopes of the region was analyzed. Classification of soils adapted to the conditions of industrial region was developed. Soils are divided by the degree of realization of soil potential. Established that development of edaphotopes and plant communities on industrial areas after the termination of human activity is similar to the genesis of undisturbed areas. Map of soil cover structures of Krivbass was developed, founded that the formation of man-made objects fundamentally broken tree-like structure of natural ground contours. Determined that vegetation of the region represented by 12 classes and 135 formations. The method of determination of soil potential by multidimensional matrix was proposed. Created three-dimensional models of surface of post-technogenic areas and the prediction models of edaphotopes and plant communities development in these areas. Proposed to create wildlife sanctuaries on disturbed areas, as reserves for the recovery and distribution of typical zonal vegetation as renewable ecological network elements.
