With the PFU method (GB/T12990 91 ), the protozoan community colonization process was studied in three urban artificial lakes. Liuhua Lake, Liwan lake, and Luhu Lake in Guangzhou. The result indicated that the numbers of protozoan species, phytomastigophora index, colonization process parameter ( S eq , G , T 90% ) , diversity index d and community pollution value(CPV) could well show the water quality. In these three lakes, totally 181 species of protozoan, including 53 phytoflagelates, 24 zooflagelates, 24 sacrcodinas and 80 ciliates were found during the investigation. The species and phytomastigophora index of Liwan Lake were 100 and 24%, while those of Liuhua Lake were 107 and 26.16%, and those of Luhu Lake were 138 and 27.54%, respectively. The PFU protozoan community colonization in Liuhua Lake reached its species maximum of 65 on the 3rd day, while that in Liwan Lake and Luhu Lake reached the species maximum of 66 and 90 on the 5th day. Though the three lakes were still in eutrophication condition, the comprehensive prevention and contermeasures including pollution cutting engineering and cleaning out the substrate sludge could decrease the inside and outside loading of nutrition and sediments, reduce the nutrition salt content of water column, and help restore the protozoan community.
