摘要：

以正在生态恢复进行中的苏州河水体为研究对象，共设黄渡、华漕、北新泾、武宁路桥、长寿路桥和浙江路桥6个采样点，从2000年10月至2002年10月间按春、夏、秋、冬进行了9次采样，另外，在黄渡、华漕和武宁路桥于2002年的5月和6月增加了5次采样，对苏州河浮游植物群落的种类组成和数量特征进行了调查研究，结果表明：苏州河浮游植物的平均个体数达到了 4.7×10⁶ ind/L，细胞密度平均值为 10.2×10⁶ind/L，生物量均值为 5.73 mg/L。苏州河浮游植物群落结构的定性和定量组分表达均显示绿藻优势，其密度和生物量分别为 5.774 ind/μL 和 2.159 mg/L；属数、种数和生物量结构以硅藻次之。生物量、个体数与细胞数的ShannonWeaver指数均值分别为3.05、3.22和3.28；生物量、个体数与细胞数的Pielou均匀度指数均值则分别为0.73、0.76和0.77，Margalef和Simposon指数均值分别为1.59和0.84.

Abstract:

Taking ecological reconstruction of Suzhou Creek as a research object,by setting six sampling points,Huangdu,Huacao,Beixingjing,Wuninglu Bridge,Changshoulu Bridge,Zhejinanglu Bridge,the survey of phytoplankton community structure was carried out.Nine samples according to the four seasons from October of 2000 to October of 2002 had been taken.Also,five more samples at Huangdu,Huacao,and Wuninglu Bridge from May to June of 2002 were added.Surveying items included species composition,dominant population,indicative species group and biomass.Through two years of intensive studies,following conclusions were drawn:the mean values of individual number,cell densities and biomass were 4.7×10⁶ind/L，10.2×10⁶ind/L and 5.73 mg/L,respectively.Chlorophyta always was the first dominance upon the generic number,species number,density,biomass of phytoplankton community in Suzhou Creek.Bacillariophyta was the second upon the generic number,species number,and biomass of phytoplankton community.The ShannonWeaver indices mean values of biomass,individual number and cell number were 3.05,3.22 and 3.28,respectively；The mean values of Pielou indices of biomass,individual number and cell number were 0.73, 0.76 and 0.77,respectively，and the mean values of Margalef and Simposon indices were 159 and 0.84
