Investigation of Zooplankton Community and Diversity Assessment in Water Source Area of the East Line Project of Transferring Water from South to North
Zooplankton investigation was carried out in water source area of the East Line Project of Transferring Water from South to North at spring,summer, autumn and winter in 2013. The species distribution,quantity distribution,dominated species and species diversity were analyzed. Results showed that 34 species were identified,which belong to 3 phylum and 21 family and 23 genera, with K.cochlearis,K.quadrata,B.angularis and M.leuckarti as dominate species. The index of abundance of zooplankton was 37.88 ind/L. Shannon-Wiener index,Margalef index and Pielou index were 2.41, 1.89, 0.78 respectively. The overall evaluation result of water quality was oligosaprobic to mesosaprobic.
