Malyarenko A. Modeling of regional ecological network in the Northern Pryazov'ya.

The conceptual foundations and the procedure for mathematical-geoinformation modeling of the regional ecological network for structurally multiform and essentially anthropized regions (regionally-specific ecological network) were substantiated and developed. There were proposed the formalized modes of ecological network region's structuring with its initial division into (quasi)natural, natural-anthropogenic and anthropogenic structures and their further differentiation onto substructures with modeling determination of their dynamics. The algorithm was devised for modeling of regionally-specific ecological network with set of criterion-conditioned operations, the implementation of which is directed to a staged creation, coordination and transformation of the defined model structures of ecological network modeling region with synchronous creation and informational acquisition of the relevant blocks of electronic database (EDB) "Regional Ecological Network". The classifications of regional ecological network's cores and corridors were improved, the classification of their buffer zones was developed and the modified classification scheme of identification criteria, level of stability, reliability and functioning efficiency of the ecological network was proposed. There was systematized and specified a set of indicators suitable for parameterization of the above criteria under conditions of the research region's heavy anthropization. The general principles and features for geoinformation modeling of regionally-specific ecological network were formulated and the initial set of EDB generation sources applicable for such modeling was determined. The implementation of the developed procedure was accomplished on the Northern Pryazov'ya example.
