GIS在海湾陆源污染物总量控制中的应用

Application of GIS to Controlling Total Mass for the Land-based Pollutants Discharged into Bay

陆源污染物总量控制是我国海洋环境保护的重要手段之一 ,对于改善我国海洋环境质量状况具有十分重要的意义。以大连湾为例采用 ARCVIEW和 ARC/INFO为 GIS软件平台建立了海湾陆源污染物总量控制信息系统。利用该系统实现了对海湾陆域社会经济信息管理、沿岸各类工业及生活污染物排放情况管理和分析、各类海洋环境监测数据管理和海域水质、底质状况评价模型的建立 ;实现了海洋环境评价工作的可视化 ,将海湾水动力模型、污染物飘移扩散模型与地理信息系统进行了集成 ,并将其结果同化到地理信息系统中来 ,以便与其他信息进行有机地复合 ,从而分析污染扩散对海洋资源的影响 ;同时还实现了海湾水动力过程的动画模拟。

The control of total mass for the land\|based pollutants discharged into bay is important one of method for marine protection in China,and also important for restoring environmental quality.In this paper,the marine geographical information system for total mass control of the land\|based pollutant discharged into bay was finished with GIS platform of ARCVIEW and ARC/INFO in example of Dalian bay in the Liaodong Peninsular.By this system we can undertake management of social and economic information in bay area,analyzing of industrial and subsidence contamination along shore,management of marine environment data from different source,modeling of marine water quality.As a result,the system integrated dynamic model and pollutant disperse model.
