Project summaryDevelopment of large resource extracting industries , different ore and non-metallic deposits, construction of industrial complexes, military test sites, including nuclear test sites, cities and villages, communications, transport roads, electro-transmission lines, gas-oil pipe-lines, irrigation hydroconstructions and extensive development of agriculture in the Kazakhstan Republic led to considerable disturbances and contamination of vegetation and soil cover, desertification, degradation and development of erosion processes. The soils of all bioclimatic zones from chernozems of the North to piedmont sierozems and mountain soils of the South are subjected to disturbances. The disturbances enumerated above have been developing for 30-50 years.
Technology of open exploitations was widely used in 60-70th, as the mostly effective method, but the elaborators didn’t take into account the great damage that negatively influences on environment and health of people living in industrial regions. Their adaption to new conditions goes on with difficulties, endemic diseases increase, some hereditary changes take place in people populations.
Study of evolution processes in technogenically disturbed landscapes under natural conditions and conditions of recultivation helps to understand the problems of soil and vegetation cover formation, optimization of prognosis on the duration of the disturbed ecosystems’ full resoiling and revival of healthy environment as a whole.
The aim of the project is development of a technology for biologic recultivation of technogenically disturbed lands and acceliration of biocomplexes natural regeneration, resoiling of the disturbed lands for sanitation of environment on the basis of field-experimental researches of the disturbed lands.
The main tasks of the project fulfilment: study of ecologic conditions of the disturbed lands’ morphologic pecularities by description of natural and technogenic landscapes, relief of the locality and dumps (micro, mezo), climate and vegetation. To classify waste territories of different age according to the level of their overgrowing and formation of young soil. To determin the level of changes in physical, chemical and biologic properties of artificially formed soil–grounds on industrial dumps, the level of successeion development of biocenoses in conditions of recultivation. To determine the level of development and dumps’ evergrowing after biologic recultivation by woody-scrub species from the local flora, promoting formation of rich root and rootside shoots with frost–hot–gas–resistant properties.
