Application and Development of the Ecological Environment Carrying Capacity Evaluation Information System on Coal Mining

Some proper indexes, AHP method and GIS model are adopted for quantitative analysis and comprehensive evaluation of the ecological environment carrying capacity on coal mining. The ecological environment carrying capacity evaluation information system on coal mining is developed based on Visual C++ 6-0, ADO, SQL Server 2000, GIS and so on. This information system has many effective functions such as data management and procession, information query, map operation and spatial analysis, mathematical statistics, comprehensive evaluation, evaluation map drawing, visualization display and so on, and has intuitive and the spatiality characteristic, which can cause the evaluation data and the graph connection and can be the evaluation results direct-viewing demonstration on the graph. This information system was applied in the 22 plan coal mines, Shanxi.
