基于SD-GIS的突发水污染事故水质时空模拟

Spatio-temporal Simulation of Water Quality Based on SD-GIS Accidential Water Pollution

  • 摘要: 将一维河流水质系统动力学模型用于水质模拟,建立了系统动力学(SD)和GIS关联的概念框架,并基于组件式GIS和SD模型开发了水污染事故水质模拟实验系统。以2005年11月发生的松花江水污染事故为例,对特征污染物硝基苯浓度的时空变化进行了动态仿真模拟。结果显示,通过建立SD和GIS的关联,能够实现水污染事故中污染物的时空分布模拟,以及基于模型参数的模型调控与情景分析,为突发水污染事故应急方案的优选提供科学、可行的依据。

     

    Abstract: One-dimensional river quality system dynamics model is applied to the water quality simulation and conceptual GIS-SD frame is constructed.Based on ComGIS and system dynamics model,the experimental system of water quality simulation in water pollution accident was developed.The Songhua River water pollution accident was taken as an example.The spatio-temporal change of nitrobenzene concentration is dynamically simulated.The results show that the simulation of spatio-temporal distribution of pollutant in water pollution accident,model regulation,scenario analysis can be realized.
