摘　　要：[Objective] The plankton and macrobenthos samples in municipal polluted river were analyzed by different methods, so as to explore the method suitable for biological data analysis in heavy polluted area. [Method] Shannon-Wiener diversity index, cluster analysis of multivariate statistical analysis and MDS （Non-matric Multi- dimentional Scaling）analysis were used to analyze biological data of phytoplankton, zooplankton and Zoobenthos collected from the representative municipal polluted river in Pearl River Delta. The sediment samples were also collected to determine. Pb, Cd, Hg, Cr, As, Cu, Ni, Zn, as well as CODe, and NH3-N of porewater. Hakanson potential ecological risk index method was used to evaluate the ecological risk. [Re- suit] Shannon-Wiener diversity index analysis results can not effectively reflect the difference of pollution status of various stations in heavy polluted area; despite the presence of some problems, multivariate analysis method is superior to the Shannon-Wiener diversity index method in biological monitoring of heavy polluted river in the city. [Conclusion] The paper provided theoretical basis for biological data analysis in heavy polluted area.[目的]运用不同分析方法比较城市污染河道浮游生物和底栖动物样品,探讨适用于重污染区域生物数据分析的方法。[方法]采用Shannon-Wiener多样性指数,多元分析中的聚类分析法和非度量多维标度排序(Non-matricMulti-dimentionalScaling,MDS)分析法对采集自珠江三角洲典型城市污染河道-佛山水道浮游生物及底栖动物数据进行分析。同步采集底泥样品,测定了Pb、Cd、Hg、Cr、As、Cu、Ni、Zn和间隙水CODCr、NH3-N,并运用Hakanson潜在生态危害指数法对生态危害进行评价。[结果]Shannon-Wiener多样性指数分析结果不能有效地反映重污染区域污染状况差异,其分析结果与实际污染状况有较大差距;尽管存在一些问题,在城市重污染河道生物监测结果分析方面,多元分析方法优于Shannon-Wiener多样性指数法。[结论]为重污染区域生物监测数据分析提供理论依据。
