摘要
"引江济太"是近年来太湖流域实施的一项重要调水工程,根据望虞河沿线各水文监测站点的水质数据,通过相关分析并采用Borda计数方法,计算从常熟水利枢纽引水到望虞河沿线各站点及望亭水利枢纽所需的传播时间,同时通过可视化绘图方式验证所得到的传播时间。最终的目标是能够根据传播时间提出望亭水利枢纽最佳的开闸放水时机,使得入湖水能够在短时间内稀释太湖较差水质,从而为太湖流域引江济太工程的实时调度与分析提供决策依据。
Yangtze-Taihu Water Diversion is a significant water diversion project in Taihu lake basin in recent years.Based on water quality data collected from each gauging station along Wangyu River,through correlation analysis,this thesis respectively calculates water travel time from Changshu hydro-junction to each station along Wangyu River and to Wangting hydro-junction by Borda counting.Meanwhile,the travel-time can be verified by water quality’s relation graphs of two adjacent stations.The best sluicing time of Wangting hydro-junction can be defined according to the travel time,so that the poor quality water of Taihu Lake would be diluted in a short time,providing decision-making basis for real-time regulation and analysis of the project in Taihu Lake Basin.
