| 摘 要： | 2012年5月-2013年1月对上海市八区县共8条河道的底栖动物进行了调查,并对河道的水质进行了生物评价。共鉴定出底栖动物44种,隶属3门19科33属,霍甫水丝蚓(Limnodrilus hoffmeisteri)和黄色羽摇蚊(Chironomus flaviplumus)为主要的优势种。上海市河道底栖动物的年均密度为382 ind/m2,霍甫水丝蚓对其贡献率最大,其密度为214.1 ind/m2,占总密度的56.1%;年均生物量为24.62 g/m2,铜锈环棱螺(Bellamya aeruginosa)对其贡献率最大,其年均生物量为21.17 g/m2,占总生物量的86.0%。各季度底栖动物密度夏季冬季春季秋季,生物量冬季秋季夏季春季。各个区县河道密度最高的是闸北区徐家宅,最低的是闵行区友谊河。生物量最高的是金山区勇敢河,最低的是闸北区徐家宅。水质评价结果表明上海市河道水质处于轻污染到重污染状态,其中,上海市八区县8条河道中只有崇明县琵鹭河处于轻污染,青浦区中横港、宝山区毛家塘、闵行区友谊河处于中污染,嘉定区瞿门河、奉贤区新陆港、金山区勇敢河、闸北区徐家宅处于重污染。与Shannon-Wiener多样性指数(H')、Margalef丰富度指数(D)、Pielou均匀度指数(J)等多样性指数相比,BI生物指数和Goodnight修正指数(GBI)更适合评价上海河道的水质状况。

| Abstract: | From May 2012 to January 2013, zoobenthos community in 8 urban rivers of 8 districts in Shanghai was investigated. Water quality of the river was assessed based on the structure of zoobenthos community. A total of 43 zoobenthos species belonging to 3 phyla 19 families and 33 genera were identified, among which Limnodrilus hoffmeisteri (Claparède) and Chironomus flaviplumus (Tokunaga) were dominated. The annual density of zoobenthos averaged 382 ind/m2 and Limnodrilus hoffmeisteri (Claparède) contributed the most (77.4%) of the gross. The annual biomass of zoobenthos averaged 24.62 g/m2 and Bellamya aeruginosa (Reeve) contributed the most (86.0%) of the gross. The zoobenthos had the highest density in summer, followed by winter, autumn and spring. The highest biomass was in winter, followed by autumn, summer and spring. The highest density was in Zhabei xujiahzai, the lowest density was in Minhang youyihe, The highest biomass was in Jinshan youyihe, the lowest biomass was in Zhabei xujiahzai The evaluation with biological index indicated that the water quality of Shanghai urban river was of slight to serious pollution, In 8 urban rivers of 8 districts in Shanghai, only one river is in slight pollution, three rivers in moderate pollution, four rivers in serious pollution. Biotic Index (BI) and Goodnight Biotic Index (GBI) were much more suitable for the evaluation of river water quality in Shanghai urban rivers comparing with Shannon-Wiener diversity index, Margalef species richness index, Pielou index. |
