Антропогенная трансформация и устойчивость лесных сообществ в зоне влияния проектируемой Нижегородской АЭС

Abstract

Summary. The article presents the materials of studies of the state and anthropogenic transformation of forest communities in the vicinity of the projected Nizhny Novgorod nuclear power plant (NPP). Various methods of research of forest ecosystems are considered. The characteristic of breed and age structure of forest communities is given. As a result of the work, data on the state of forests on the scale of V. A. Alekseev were obtained for 5 points: from healthy to dead. Based on the results of the assessment of the state of forests determined the stability of forest ecosystems, the degree of their transformation. Types of damages of woody plants are defined. The most damaged trees of aspen (Populus tremula). They are damaged by fungal diseases – up to 64,1 % of the total number of trees of this breed. Common spruce (Picea abies) is strongly damaged by the typographer beetle (Ips typographus). The state of forests in the vicinity of the designed Nizhny Novgorod NPP is estimated as "healthy", stands – stable.
