摘    要:利用点源连续排放的解析解对FDS格式二维水流水质模型精度进行分析,应用FDS格式二维水流水质模型对长江泰州江段的流态及污染带分布进行模拟并建立了排污混合带长度与排污量的响应关系曲线,同时根据模拟结果对泰州江段岸线水质状况进行了分析.结果表明:入江水道口向上游3.6~7.2km段内及三江营至泰州引江河口段的水质状况良好,可以用作供水水源地的取水口;古马干河至如太运河河口段水质较差,需对沿岸排污口及沿线相应的污染源进行治理。

关 键 词:长江泰州江段  水环境数值模拟  水质可利用性

Abstract:The precision of the 2-D water flow and water quality model in the form FDS form was analyzed by use of the analytical solution for the continuous discharge of point-source pollution. Based on the analysis, the model was used for simulation of the flow pattern and pollution zone distribution for the Taizhou section of the Yangtze River, and the curve reflecting the relationship between the length of the pollution zone and the pollutant discharge was derived. The simulated results show that the water quality of the 3.6-7.2?km section from the river inlet towards the upstream and the section from Sanjiangying to the river mouth for water diversion in Taizhou City is satisfactory, and can be used as water supply sources, while the water quality from the Gumagan River to the mouth of the Rutai Canal is relatively bad, thus, some measures should be taken to control the discharge outlets and pollution sources along the river section.
Keywords:Taizhou section of the Yangtze River  numerical simulation of water environment  usability of water quality
