| 摘 要： | 2009年3月对珠江广州大桥到海印桥段底栖动物群落结构进行调查。共采集6种底栖动物样品,其中霍夫水丝蚓为研究区域优势类群,密度和生物量相对丰度分别为96.3%和71.9%。海印桥底栖动物密度和生物量最大,分别为305280ind/m2和664.72g/m2;中大码头次之,分别为54144ind/m2和129.27g/m2;广州大桥最小,分别为43200ind/m2和93.87g/m2。底栖动物群落结构极为不均匀,广州大桥、中大码头和海印桥Shannon-Wiener多样性指数分别为0.34、0.27、0.14;Margalef多样性指数分别为0.32、0.19、0.11,均匀度指数0.19、0.20、0.13,物种丰度分别为6、4和3,属严重污染水平。对理化指标进行分析表明,溶解氧过低是生物多样性低的直接原因,控磷、除磷对降低水体营养水平,恢复生物多样性意义重大。

| Abstract: | Macroinvertebrate community structure was studied in the Pearl River Guangzhou bridge to Haiyin bridge portion in March 2009.The results showed that six taxa were collected,and among them Limnodrilus hoffmeisteri was the dominant taxon,with density and biomass relative abundance were 96.3% and 71.9% respectively.Haiyin bridge was the biggest site in density and biomass,with them were 305280ind/m2 and 664.72g/m2 separately;followed by Zhongda dock site,with them were 54144ind/m2 and 129.27g/m2;and lowest in ... |
