基于Mapinfo和Surfer的大气污染扩散预测系统

Atmospheric pollution dispersion prediction system based on Mapinfo and Surfer

基于Mapinfo和Surfer,建立大气污染扩散预测系统,实现污染源下风向预测点污染物浓度的快速、准确预测,且能准确绘制预测大气污染物扩散等值线图并将其直观显示。以平顶山某煤矿为例,预测该煤矿某污染源下风向污染物浓度,同时在Mapinfo中将其与影响区域地形图叠加分析,给出控制该区域污染的建议。

Based on Suffer and Mapinfo, the atmospheric pollution dispersion prediction system was built. Using this system, the pollution concentration of the predicted point could be calculated quickly and accurately, besides, the pollution dispersion could be predicted too which would be visualized as isoclines. Taken one of the coal mines in Pingdinshan city as example, we predicted the pollution concentration which was overlapped with the map of this area in Mapinfo, based on these data, how to control the pollution of the area was suggested.
