摘    要:大气污染事故预测预警系统主要包括污染气象模型和大气扩散数学模型,利用地理信息系统(GIS)技术,按照污染事故发生的地理位置,将模型的数值解和GIS相结合,从而可以在时间和空间上对污染扩散进行分析,得到不同地点的污染物浓度和污染程度,获取受污染范围内的人口和周边单位等重要信息,从而预测污染事故对环境的影响程度和范围,为突发性环境污染事故的应急监测、现场救护和灾后评估提供科学依据。

关 键 词:预测预警  污染事故  污染物扩散  数学模型  地理信息系统

Abstract:A mathematical model system on the prediction and alarm for sudden air pollution accident was develped,which was consisted of meteorological model, atmospheric diffusion model and GIS.The data solutions gained from the model combining with GIS make an analysis of the diffusion of pollution.In that case,the spatio-temporal concentrations and the level of the pollutants canbe acquired.Moreover,the important information on population and institutes nearby can be obtained.Thus,it is available to predict the influence degree and extent by the pollution accident.The system can also provide a scientific support for emergency monitoring monitoring,field rescue and calamity survey.
Keywords:prediction and alarm  contamination accident  pollutant diffusion  mathematical model  GIS
