Abstract
Urals, the natural border between Europe and Asia, is stretching more than 2000 km in the meridional direction. It crosses a number of natural zones of typical tundra to steppe, which, combined with high-altitude zone in the region creates a unique variety of geographical environment conditions. This diversity results a high degree of species and ecosystem biodiversity on the Urals part of the biosphere. Recent biocenotic cover, which is dominated by forest communities, formed during the postglacial period, but retained in its composition relic and endemic elements of flora and fauna, which significantly increase the biodiversity of the biota. Development Urals anthroposphere has its own specific features. Until the XVII century the population of the region were few and mainly engaged in animal husbandry, hunting and fishing. These activities do not cause almost no damage to the nature of the region. The industrial development of the Urals begun in XVII century. The main development was received mining, metallurgical, chemical, timber industries. The largest scale of these industries have purchased in the Middle, in part of Southern and Northern Urals. Urals - one of the most industrialized regions of Russia, the bulk of whose population lives in industrial centers. Currently, industrial areas of the Ural region are characterized by a significant degree of disturbance of the biota, loss of a significant proportion of biodiversity, a high degree of environmental pollution. Many industrial conglomerates have reached a state of ecological crisis. Therefore the problem of biodiversity conservation in the Urals is more than topical in industrialized areas particularly. One of the main ways to solve the problem - the development of network of reserves, which is based in the Ural region on 15 nature reserves and national parks. Development and improvement of reserves network in order to maximize preservation of the individual components of the biota of the Urals and biodiversity of the region as a whole, as well as to optimize the relationship of his anthropo- and biospheres was reflected in the decision of UNES CO on the establishment of the two, the World Network of Biosphere, Reserves. One of them is located in the North, the second in the Middle Urals. The Middle Urals is the territory, where mountain-industrial complex have a most development. Therefore situated here Visimsky Biosphere Reserve can be a model for testing the mechanisms of building relationships anthropo- and biosphere to preserve biological diversity of the biota in terms of further development of existing socio-economic specialization anthroposphere. The territory of refuge - a single forest, which is situated in the middle part of the Ural Mountains, with elevations ranging from 400 to 699 m. Since the turn of XVII-XVIII, as the industrial development of the region, the forests were in a versatile heavy-duty use. They were cut down for various purposes in large scale, repeatedly burned. Therefore, in the industrial areas of the Middle Urals are now dominated derivatives and quasi-indigenous forests as well as non-forest areas. Indigenous forests have survived in small isolated areas and make up about 1 % of the area of the region. To preserve the biodiversity of the biota of these samples was formed Visimsky Biosphere Reserve. But even in its territory primary forest ecosystems occupy about 6 % of the area and are concentrated mainly in the protected area. Almost all the rest of the territory is occupied by the derivative forests, at different stages of restoration successions. One of the main objectives of the existence of the reserve - the restoration of the original ecosystem diversity, a source of which must be preserved areas of primeval forests and monitoring of recovery processes in areas of refuge with varying degree of human influence.
