Geoinformation systems for regional environmental studies

摘要

Models and methodological developments in Geographical Information Systems (GIS) for regional environmental analysis and environment rehabilitation are considered. Generalized environmental pollution index taking into account arbitrary number of chemical contaminants in environment is introduced for solving the region environmental problems. An approach to identifying of environmental danger zones on a region territory was developed. The zones are represented on a computer map of the region. A procedure of choosing of the technologies for cleaning air with the use of geoinformation technologies on the basis of the results of the regional environmental analysis is developed. The procedure is suitable for development of practical recommendations for a choice of nature-protection technologies on the basis of the analysis and prediction of changes of the environment. A procedure of predicting environmental danger zones evolution is discussed. The procedure is based on analysis of the regional economic development scenario. The results of analysis of regional environmental state with application of GIS-technologies are illustrated on computer maps.
