摘要
基于ArcGIS平台,构建了一个基于高斯扩散模型的工业气体污染泄漏模型,预测南京市大气污染范围。该模型将ArcGIS空间分析功能与高斯扩散模型有机集成在一起,可就污染范围进行定性和定量分析,包括浓度预测、浓度分级、受灾评估和辅助决策四个功能,并自动生成分析报告。模型简单,运行效率较高,得出的结果相对科学、准确,对灾害评估和政府应急决策具有一定的现实指导意义。
Based on ArcGIS platform,a pollution leakage model of industrial gas is developed by Gauss dispersion model in order to forecast the atmospheric pollution range in Nanjing.With its four functions of concentration prediction,concentration grading,damage assessment,decision support and by integration of the spatial analysis of GIS with Gauss dispersion model,quantitative and qualitative analysis of pollution areas is carried out as well as the analysis report is automatically generated.This model is simple and efficient,with relatively scientific and accurate results,thus it will give practical significance to disaster assessments and governmental emergency decisions.
