Kopiy M. Phytomeliorative role of vegetation in devastated lands reproduction within the limits of sulfur quarries of Western Forest-Steppe

Object of study – devastated lands within the limits of sulfur quarries of Western Forest-Steppe. Aim of the study – to establish phytomeliorative role of vegetation in disturbed lands restoration within sulfur quarries and to improve the design and economic measures for the activation of reproduction disturbed landscapes and their subsequent use. Research methods: comparative ecology, geobotanical, forestry-taxation, agrochemical, electrophysiological, spectrophotometric, bioindication, mathematical-statistical. Theoretical and practical results. The peculiarities of plant groups formation on degraded lands with different degrees of reproduction, their influence on the distribution of nutrients in the soil, the mycological structure of the soil, the dynamics of seasonal flow of CO2 from technozemes, the growth and state of different compositions of tree plantations within the limits of sulfur developments of Western Forest-Steppe are found out; planning and economic measures in usage of devastated lands for the formation of recreational facilities and forests are improved. Originality. For the first it is established that the formation of complex species composition and structure of plant associations promotes the humification of technozemes in the surface layer of soil (up to 10 cm), increasing the content of Nitrogen and optimizing pH level; in areas with complex plant communities, it is observed the growth of biodiversity of soil fungi, which form clusters of 3–5 species of the genus; it is investigated that the specific flow of CO2 from the surface of technozemes depends on the season of the year, which depends on the remediation option and the species composition of plant groups; it is established that the maximum specific flow of CO2 is characteristic feature of technozemes under oak and poplar plantations, in which the C:N ratio is maximal. The degree of implementation. The results of researches are used by: Lviv region Department of Forestry and Hunting; State Enterprise «Lviv forestry»; the materials of the dissertation work are used in the scientific and educational work of Ukrainian National Forestry University in the lecture courses of educational disciplines «Soil microbiology», «Forest reclamation of devastated landscapes», «Biotechnology». Sphere of use. In educational and scientific activities of higher educational institutions of the agricultural profile, state enterprises of forest and ecological profile, ecology and forestry departments of Western Forest-Steppe territory.
