Pavlishyna O. Forest-meliorate efficience of forest protective stands along Northern part of South-West railway.

The thesis is devoted to the researches of forest-meliorate efficiency of forest protective stands along Northen part of South-West railway. The current state of afforestation on the adjusted territories of Northen part of South-West railway, age structure, species composition and construction particularities of phytocenosis have been analized. It's determined the forest estimation indices of protective stands. The acoustic efficiency of railway stands in dependence of width strip, construction particularities, assortment of wood species and vegetative seasons has been researched. It's found out the accumulate properties of forest strips in accumulation of heavy metals (Cu, Zn, Pb, Cd) by leave area of crowns. It's researched the intensivity of accumulation of heavy metals in the leaves of common oak in the next order: Zn (6,44) > Cu (5,94) > Cd (1,75) > Pb (1,35). The aesthetic evaluation of phytocenosis has been done and the list of prospect of wood species with high ecological peculiarities, decorate properties and attractivity have been developed. It's proposed the recommendations of practice for increasing of forest meliorate efficiency of phytocenosis at the territories ajucted to railways their sanitary-hygienic functions and aesthetic significance within railway stations and green zones.
