Abstract

Prediction models and methodological developments in geographical information systems (GIS) for regional analysis and predictions of environmental states are considered. The complex and interdisciplinary nature of environmental problems requires the development of a new class of GIS, integrating mathematical models, databases and expert knowledge based on a conceptual model. It is known that chemical contamination is one of the main factors of the environmental pollution of regions. Therefore, a new environmental quality index, taking into account the chemical contaminants' parameters, is created for solving regional environmental problems. An approach to identifying environmental danger zones (EDZs) in a region's territory was developed; the zones are represented on a computer map of that region. A GIS technology scheme for predicting EDZ changes is discussed. The scheme is based on using an analysis of the region's economical development scenario. Samples of regional environmental prediction for the Siberian region are given in this paper.
