中文摘要:
      滴水湖是一个典型的城市人工湖,作为上海临港新城景观及水利核心,承担着防汛排涝、置换水体等重要功能。采用综合水质标识指数(water quality identification index,WQI)评价法分析了对滴水湖及其入湖河道2018年8月至2019年7月间水质时空分布差异,并对水质主要影响因子进行分析。结果表明,滴水湖及入湖河道的水质具有空间上的差异性,外涟河、中涟河、内涟河、入湖口为"中等",水质滴水湖区为"良好",从外涟河到滴水湖区的水质呈现出逐渐变好的状态;和WQI显著相关的水质参数有总氮、氨氮、水温等;水质季节变化主要影响因子为水温和降水,空间变化主要影响因子为引水水源水质和人类活动。最后,根据该区域水质特征和影响因子,提出了生物治理法、改建雨水排放管道和加强重要指标监测等治理对策。
英文摘要:
      Dishui Lake is a typical urban artificial lake. As the core of Shanghai Lingang New City landscape and water conservancy, it undertakes important functions such as flood prevention and drainage and water replacement. This study mainly used the water quality identification index (WQI) evaluation method to analyze the temporal and spatial distribution of water quality in the Dishui Lake and the rivers into the lake from August 2018 to July 2019, and analyze the main factors affecting water quality. The results show that the water quality of Dishui Lake and the rivers into the lake are spatially different. Wailian River, Zhonglian River, Neilian River and the mouth of the lake are "medium", and the water quality of Dishui Lake area is "good". The water quality in the Dishui Lake area has gradually improved; the water quality parameters that are significantly related to WQI include total nitrogen, ammonia nitrogen, and water temperature; the main influencing factors of seasonal changes in water quality are water temperature and precipitation, and the main influencing factors of spatial changes are the quality of water diversion sources and human activity. Finally, according to the water quality characteristics and influencing factors of the region, the biological treatment method, the reconstruction of rainwater discharge pipelines, and the strengthening of monitoring of important indicators are proposed.
