黄浦江上游来水与黄浦江水源水质内在关联研究

The relationship between upper reaches and the water quality in the water intake of the upper stream of Huangpu River

使用有机污染综合指数评价和数理统计方法 ,对 1986— 2 0 0 0年黄浦江水源地及黄浦江上游来水的水质监测数据进行分析。结果表明 ,黄浦江水源近 15 a水质变化可分为缓慢恶化、加速恶化和逐渐改善 3个阶段 ;黄浦江松浦大桥取水口水质与园泄泾相近 ,且均劣于淀峰和太浦河 ,优于大泖港 ;大泖港与松浦大桥水质密切相关 ,对松浦大桥取水口水质恶化贡献很大。

Bivariate correlate, partial correlate, regression, pair-sample t test and exponential method are applied to analyze the monitoring datum of water quality during 1986~2000. This paper indicates that: Three phases: slow deterioration, accelerated deterioration and gradual amendment of water quality changes were divided. The water quality near the water intake was similar to that in the Yuanxiejing Stream, worse than that in the Dianfeng and Taipu Stream, and better than that in the Damaogang Stream. The water quality of Damaogang Stream had good relationship with that of the water intake, and it was the main reasons for source water deterioration. The variance trend of the water quality in the water intake was simulated based on the mechanism.
