Raspopina S. Transformation of pine forest ecosystems under the impact of technogenic air pollution in mid parts of Seversky Donets river basin

The object of the study - transformation of pine forest ecosystems under the impact of technogenic pollution in mid parts of Seversky Donets river basin. The aim of investigations - to study the impact of thermo-electric power stations' and cement industry emissions on pine forest ecosystems of mid parts of Seversky Donets river basin. The investigations were carried out according to common methods. The level of technogenic load on forests was estimated, and the sanitary and hygienic role of forests was confirmed as the considerable amount of pollutants are sedimented here. The effects of industrial pollution of forest soils were found that reflected in deteriorating the state of forest stands and in decreasing pine radial increment. The methodical recommendations for the diagnosis of the state of pine forest ecosystems and for basic principles of forest management in conditions of technogenic air pollution were proposed. The field of practical use of results - in forest management under the conditionsof technogenic air pollution. The area of application - forest management.
