Influence of aerotechnogenic pollution on the spatial structure of pine stands
Journal Title: Лісівництво і агролісомеліорація - Year 2012, Vol 121, Issue
Abstract
Aerotechnogenic transformation of pure middle-aged pine stands of the pine-forest terraces of Seversky Donets River in cоnditions of environment pollution by emissions of “Balcem”, JSC, was investigated. For 1989–2010, despite the decrease of “Balcem” emissions to atmosphere, no positive changes in condition and taxation parameters of pine stands were detected in man-made area. Significant decrease in size and shape of crowns was registered. The crowns have average or small length. Crown area, volume and the ratio of crown length to tree height decrease with crown deterioration. Such negative changes have lead to structural failure, decrease of key taxation parameters and potential of pine ecosystems in these technogenically influenced conditions.
