巢湖生态调水的水质约束条件

生态调水是巢湖水污染综合治理的一项重要措施,长江又是巢湖生态调水的水源区与排泄区,为确定长江和巢湖生态调水的水质重要约束条件,通过分析江(长江)湖(巢湖)水质数据、总结江湖水质变化规律和趋势、利用统计学中方差分析的方法,定量判断了各水域分月、分季水质差别。结果表明,长江水质总体较好,生态调水的水源不会对巢湖的水源地水质产生负面影响,但应考虑避免在冬季进行调水。

Water Quality Constraints of Chaohu Lake Ecology Water Transfer Programs

Ecology water transfer is one of the most important measures for water pollution control in Chaohu Lake. The Yangtze River is not only the source area but also the excretion area of Chaohu Lake ecology water transfer. Water quality is one of the most important constraints of ecology water transfer opportunity and plan. This article reorganizes the water quality data of the Yangtze River and Chaohu Lake, sums up the water quality change rule and tendency of river and lake. Then it determines the monthly and seasonal water quality difference between each area with variance analysis method in statistics. The results show that the water quality of the Yangtze River is good in general; the water sources of ecology water transfer has not impact on the water quality of water sources in Chaohu Lake, but it should consider not transferring water in winter.
