Ecological framework as nature conservation system

Ecological framework is a compensatory territorial system consisting of an interconnected network of sites with various restrictions on use; its main goals are maintenance of ecological stability, continuous cycles of renewal of resource potential and biodiversity conservation. Within the program of land use optimization we offer a variant of organization of an ecological framework on the Ob and the Tom interfluve. This territory is quite cultivated with a complex landscape and an economic structure. It is necessary to regulate ecological and economic relations there. Reserved territories and territories of the limited land use with high conservation level are classified as key territories. Natural ecological corridors of the Ob and the Tom interfluves are contemporary and relic river valleys, forests of the water protection zone, the forest shelterbelt, high-voltage lines, gas and oil pipelines, and other linear objects. Local elements of the framework correspond to the nature reserves in functions and organization type. To organize an ecological framework we considered territories with a partial load mode of using where conditions remain close to the natural landscapes. Such zones are not completely excluded from the economic land use; a248special mode of land use is established. We also take into account zones with intensive nature using for the subsequent analysis of the territory. After the analysis of the ecological framework it is obvious that the Ob and the Tom interfluve actually possesses all its elements. However, today the framework elements on the investigated territory are isolated and do not make a unified functional system. The fragmentation of natural landscapes, disturbances of ecological communications is evident, the ability to self-restoration decreases. A different approach to planning and land management is vital which must consider the territory's ecological features. First of all, a series of measures are necessary for the restoration of the standard of agriculture based on ecological principles. Special attention should be paid to preservation of natural sites - biodiversity reservoirs. A correctly created ecological framework of the territory is a basic supporting element of its sustainable development.
