SOME APPROACHES TO GEO-ECOLOGICAL ESTIMATION OF REGIONAL GEOSYSTEMS OF THE REPUBLIC OF TATARSTAN

Уленгов Р.А., Уразметов И.А.
There have been identified seven regional geosystems characterized by the ecological and faunistic properties typical of them. The geosystems have been distinguished on the basis of the following parameters: landscape peculiarities of the territory, the state of demographic situation, the extent of the territory economic transformations and the pattern of the distribution of bird fauna population. There has been done the estimation of the geo-ecological state of the regional geosystem based on the data of the geosystems area ratio and their functional purpose, forming special areals and distinguished by the quality characteristics. The differentiation of geosystems has been carried out based on the calculated coefficients of anthropogenic transformations as well as degree of the ecological-and-economic state of the geosystems. The bioecological characteristic of the bird fauna of the selected natural-and-territorial complexes has been given on the basis of the landscape-and-areal analysis. An attempt to identify direct and indirect relation between the indicators of the bird fauna population and ecological-and-economic state of the territory has been undertaken.
