The communities and biodiversities of zooplankton,including species composition,density,biomass and biodiversity index were studied at four sampling stations in Xin River(1#,2#) and QianTang River(3#,4#) of Ningbo from December 2007 to January 2008.24 species of zooplankton were found.Brachionus calyciflorus dominated in Rotifera,and Mesocyclops leuckarti dominated in Crustacea.There were more species of zooplankton in stations 1#and 3# than those in stations 2# and 4#,and so were the biomass and biodiversity index.ANOVA results showed that there were significant differences of Brachionus calyciflorus density and biodiversity index of zooplankton in the four different sampling stations(p<0.05.) Multiple comparison showed that obvious differences of Brachionus calyciflorus density could be observed between 1# and 2#,1# and 4#(p<0.20).There were obvious differences of rotifers biodiversity index between 3# and 4#(p<0.20),and so were the biodiversity index of Crustacea between 1#and 4#,1# and 2#,3# and 4# respectively(p<0.20).
