Abstract:: Based on the investigation of the phytoplankton in five landscape-lakes,that is,Shichahai Lake,Kunminghu Lake,the Olympic Lake,Chaoyang Park Lake,Yuyuantan Park Lake in Beijing,the biomass,species composition,Margalef’s species richness index,Shanon-wiever’s diversity index,Pielou’s uniformity index of the phytoplankton are contrasted and analyzed.The results show that the others are all identified as eutrophic water body except Olympic Lake,and the qualities of Kunminghu Lake,Olympic Lake and Shishahai Lake are somewhat better than the rest.Besides,composition and the biological indexes of the phytoplankton were used in the cluster analysis,the result is that the Olympic Lake,Chaoyang Park Lake and Yuyuantan Park Lake are in the same category,as for biological index,Chaoyang Park Lake and Yuyuantan Park Lake are in the same category which means reclaimed water has great influence on species structure of phytoplankton,while water quality has the same tendency with biological index.
