Ландшафтно-экологическая характеристика и состояние лесных насаждений промышленных центров Предуралья

Abstract

In work the landscape and ecological characteristic of the industrial centers of the Cis-Urals is submitted (Ufa, Sterlitamak, Salavat). The ecological condition of the industrial centers is defined by technogenic environmental impact, expressed and various on physical and chemical characteristics. Forest plantings of sanitary protection zones of the production enterprises and the cities perform buffer functions, absorb and accumulate the connections polluting a surrounding medium. At the wood plants growing in extreme conditions of the industrial centers delay of body height and development, decrease in a biotic state, drying up and premature death is noted. The Betula pendula Roth is widely presented in sanitary protection to plantings of the industrial centers. Are cited data in size of asymmetry of a leaf of a birch, results of calculations for a student criterion and on Fischer's Criterion are presented. The quantitative characteristics of morphological changes of the assimilatory device of a birch in contrast forest vegetation conditions of the production cities are submitted. Violations in formation of sheet plates on a number of signs are revealed. At the same time plantings of a birch successfully grow in the conditions of the production cities and successfully perform protective functions.
