Abstract
The history of research of protective afforestation was investigated, the present state and prospects of development of railroads protective afforestation of Left Bank Forest-Steppe were considered. Multifunctional effect of protective forest plantations on the railway transport were described. The distribution of the total area of protective forest which subordinate to the railways for administrative identity and for distances of protective forest plantations in the Left-Bank Forest-Steppe were considered. The scheme of administrative regionalization of the Southern Railway was shown. We described the distribution of area of protective forest plantations by type of habitat conditions and distribution of areas of shelter belts for wood and shrub species for Sumy distance of the Southern Railway. Different structures of snow holding and wind breaking wood were discovered. We found that the most snow holding and wind breaking features had shrubs and the best aerodynamic and snow holding properties had the systems with narrow and belts with low lane and with wide intervals between belts and their creation can reduce the area of land occupied by forests, and the costs of a third at planting. In addition it should be emphasized that forest plantations are cheap, reliable and long-term biological means of protecting the railroad tracks from the negative impact of natural phenomena. The application in the manufacture of circuit mixing and placement of trees and shrubs in the area of plantations significantly fetter the use of mechanical work at all growth stages and content landings. The necessity of scientifically-based approach to the regulation of protective plantations adjacent to railway stations and highways was shown. It is also advisable to examine the contribution of protective forest plantations in creating of a biological filter against contamination spread to nearby areas. The forest-reclamation properties of the stands were estimated for comprehensive management of the environmental situation at the facilities of railway transport.
