摘要： 探讨了苏州河8个断面着生生物在不同季节的种类组成、优势种密度、群落结构与水质的关系.研究结果显示，着生生物种类数以夏季最多，优势种密度以夏、秋季最大，多样性指数、均匀度指数的变化趋势与水质指标的监测结果基本一致；经相关性分析表明：水体中氮、磷含量分别与生物多样性指数、均匀度指数、藻类密度和总生物量四项指标呈显著负相关， CODcr、BOD5与四项生物指标均无相关性.各断面污染程度为上游赵屯、黄渡断面污染最轻，武宁路桥、北新泾断面污染最重，反映在群落结构上是上游以自养性藻类为主，中、下游以异养性动物为主.以上结果表明着生生物群落结构的变化能反映水环境质量的变化.

Abstract: This paper investigates the relationship among the species composition, density of dominant species and community structure of periphytons, and water quality at eight transects along Suzhou Creek in different seasons. The results showed that the species number of periphyton was the greatest in summer and the density of dominant species was the highest in summer and autumn, and the water quality was generally consistent with the tendency of the changes both in the indices of diversity and evenness. There were significant negative correlations between the contents of N and P in water, and the indices of diversity, evenness, algae density, total biomass, while CODcr and BOD5 did not show any significant relationship with these four biological indices. According to above results, the pollution level was relatively low at the transects of Zhaotun and Huangdu, while relatively high at the tansects of Wuning Road and Beixinjing. With regard to the community structure, the dominant species at the upstream were mainly autotrophic algae while those at the middle and downstream were mainly heterotrophic animals, which indicates that the changes in the community structure could reflect the changes in water quality.
