摘要： 水质模型一旦应用于某一实际水体就必然与区域水环境相联系,因此对包括污染源在内的各种水环境系统要素进行空间分析具有重要意义。本文以上海污染最为严重的水体苏州河为例,在大量实地调查获得的苏州河污染源资料,水文水质同步监测数据,区域人口数据的基础上,开发并建立了苏州河水环境信息系统,并以此为技术支持,运用水质数值模拟及其与GIS相结合的技术,研究了苏州河水体水质的时空变化规律。证实在苏州河市区段存在着一条明显的污染带,并论述了这条污染带在苏州河涨落潮的不同流场作用下,在河道内不断往复运动的规律。

Abstract: The mathematical models and Geographical Information System (GIS) are the powerful ap-proaches and technical supports for the researches on urban water pollution. This paper pointed out that CD the regional environmental elements are of great importance when a water quality model is applied to a specific water body, therefore, the spatial analysis for the elements of the water environment, including the pollution source analysis, is of great significance, and GIS can be used as a pre-processor for solving this problem with its powerful function of spatial analysis; (2) the results from the water quality model can be visualized and showed in GIS, which become a postprocessor of the model. Regarding Suzhou Creek, which has been being seriously polluted in Shanghai City, as an example and based on a large amount of data and materials from pollu-tion source survey, this paper first developed the Water Environment Information System for Suzhou Creek based on ArcView, which formed the basis of the analysis of pollution sources and water quality simulation, and then simulated the characteristics of water quality variation of Suzhou Creek with the method of the integration of water quality model (WASP4) and GIS (Ar-cView). The results of the simulation are visualized in the ArcView windows through a data transformation program.At last. we discussed the characteristics of time and spatial variation of water quality for Suzhou Creek, and verified that there is a "Pollution Belt" in the course. The reciprocation characteristics of this "Pollution Belt" is also discussed.Based on the research work above, we believe that the integration of the environmental mathematical model and GIS is of great significance and will have bright future.

Key words: numerical simulation of water quality, GIS, Suzhou Creek, pollution belt
