摘要
根据水污染事故发生、发展具有诸多时空和污染源类型不确定性的特点,以及污染事故控制与处理的时效性和最大限度减少损失的原则,采用弹性组织出事现场信息的方法,分析污染事故的基本状况,实现河流水污染突发事故影响状况的高效模拟.将GIS与水污染模型技术相结合,开发了适合长江三峡水环境决策管理的水污染事故模拟子系统.系统可反映污染事件造成的水污染状况及其时空变化过程,能为突发性水污染事故处理提供强有力的决策支持.
In consideration of the indeterminateness in spacetime distribution and pollution sources of sudden water pollution and on the basis of the time effectiveness of pollution control and remediation and the principle of decrease of pollution losses to a minimum, an analysis was made of the present situation of pollution accidents by flexible description of the pollution information, realizing a highly efficient simulation of the impacts of sudden pollution in rivers. Furthermore, a subsystem for simulation of water pollution accidents suitable for decisionmaking in management of water environment of the Three Gorges was developed by integration of GIS with the technology of water pollution modeling. The subsystem can reflect the specific situation of pollution accidents and its spacetime variation, provide a powerful support for decisionmaking in treatment of water pollution accidents.
