Popovych V. Ecological and technogenic dumps danger and scientific basis phytomelioration measures of decommissioning

The thesis is oriented forward to environmental threat in the areas with high level of technogenic impact, which is formed by landscape transforming factors of rubbish dump functioning. Complex of scientific, organizational and technical measures of rubbish dumps removal from service by applying phytomelioration has been substantiated. Impact analysisof rubbish dumps on the environment and human body has been conducted.The author highlights the recultivation and phytomelioration features of the devastated landscapes in Ukraine and abroad. The paper studies the typification of rubbish dumps on the basis of genetic, engineering and geological, edaphic, climate, ecological and technogenic features. Experimental edaphic and climate researches of rubbish dumps, taking into account their geographical and forest zoning, have been conducted. The author examines the features of biogenous destruction of consumer waste and its dependence on microorganism viability. Specific structure and composition of plant groups, created in the process of natural overgrowth are analyzed, and features of their rise and evolution are explored. Successive stages of rubbish dumps vegetation are considered. Parameters of physiological firmness of rubbish dumps weed groups are experimentally studied and the paper outlines the dependence of plants protective functions on ecological factors. The author works out the models of phytocenosis-ameliorants for rubbish dumps removal from service and environmental conditions improvement. Practical value of the thesis in question is confirmed by utility model patents and implementation acts in educational and production processes. Key words: rubbish dump, environmental threat,environmental hazards, landscape transforming factors, temperature conditions, temperature field, biogenic destruction, ecological succession, phytomelioration.
