水污染事故水质时空模拟和动态调控仿真系统研究

The Research of Temporal-Spatial Simulation and Dynamic Regulation System of Water Quality on Sudden Water Pollution Accidents

针对我国面临的重大水污染事故,结合一维系统动力学水质模型,将SD模型与GIS关联集成,开发基于二、三维一体化的水污染事故水质时空模拟和动态调控仿真系统;以2005-11发生的松花江水污染事件为例,进行水质模拟结果验证和可视化动态调控示范等,在时间和空间两个维度上对污染带迁移和转化进行动态模拟和趋势预测,实现了突发水污染事故水质浓度的模拟、预测和基于不同应急策略的模型调控。

Aiming at the serious water pollution accidents happened in China, combined with pre-established 1D system dynamics water quality models and integration of GIS with system dynamics （SD）, a realspace system of spatial-temporal simulation and dynamic regulation of water quality in water pollution accidents is developed; The Songhua River water pollution accident which happened on November, 2005 was taken as example to make validation of simulation results and visual dynamic regulation. Dynamic simulation and trend forecast of pollutants transport and transformation is made in spatial and temporal dimension. The sim- ulation, forecast of water quality and model regulation based on different emergency response strategies in water pollution accident is realized.
