摘要
松浦大桥取水口是黄浦江上游饮用水水源保护区范围内的备用取水口,研究该地水质变化规律对保障上海市民用水安全具有战略意义。文中使用水质污染指数评价和数理统计方法,分析研究了2017年—2022年黄浦江上游来水、潮流量对松浦大桥备用水源地水质的影响。结果表明,近6年黄浦江上游松浦大桥备用水源地水质呈现稳中向好趋势。上游胥浦塘蒋古渡来水水质得到明显改善,且对松浦大桥备用水源地水质提升的贡献率最高。水质污染指数与松浦大桥断面年潮流量无显著相关性。因此,上游来水污染物汇入量的下降减轻了备用水源地环境承载负荷,河流自净能力得到盈余,水质得到不断改善。
The Songpu Bridge water intake is a backup water intake within the source water protection area for drinking water in the upstream of Huangpu River.Studying the changes in water quality in this area has strategic significance for ensuring water safety for Shanghai citizens.This paper used water quality index evaluation and mathematical statistics methods to analyze the impact of the upstream Huangpu River and tide flow on the water quality of the backup water source of the Songpu Bridge from 2017 to 2022.The results showed that the water quality of the backup water source of the Songpu Bridge in the upstream of the Huangpu River had shown a steady and progressive trend in the past 6 years.The water quality of the upstream Xupu Pond had been significantly improved,and had the highest contribution rate to improve the water quality of Songpu Bridge backup water source.There was no significant correlation between the water quality index and the annual tidal flow of the Songpu Bridge section.The decrease in the inflow of upstream water pollutants has reduced the environmental load of the bakeup water source so that the self-purification capacity of the river has been surplus,and the water quality has been continuously improved.
