Landscape-Ecological Zoning of a Territory as the Basis for Identifying Lands of the Ecological Framework of an Administrative District

A landscape and ecological zoning is carried out for the preservation of geosystems of high ecological value and for substantiating of their inclusion in ecological frameworks of territories of a different rank. This type of zoning is regarded as a combination of territorialy interconnected groups of geosystems in terms of the set of physical-geographical factors, and structural and functional features. For the Vaninskii and Sovetsko-Gavanskii municipal districts of Khabarovsk krai we identified geosystems of high ecological value at the regional level. The specially protected areas now make up a mere 26.8% of their total area, and this is inadequate to ensure their conservation. It is therefore worthwhile to include in the recommended ecological framework of municipal districts this category of geosystems with the necessary regulations of the modalities of nature management. As a special element of the ecological framework of the territory, the area of the conventionally unchanged and slightly modified geosystems with ecological functions of regional significance will additionally make up 26.3% (taking into consideration their inclusion in a number of other elements of the framework). As a result, the total proportion of lands in the ecological framework of the districts will be increased to 58.6% of their area, which corresponds to the optimal indicators of rational nature management in the subzone of the middle and southern taiga.
