Many biodiversity indices were used to indicate the biological contamination degree in studies of lake water or seawater.Some were studied on biodiversity comparison for different areas at the same time,or initial structure succession of some aerial lake water systems.The phytoplankton changed with the development of various dominant species.In this study,the dominant species at these stages were Chlorophyta in the beginning stage,Cyanophyta in the second stage,and Xanthophyta in the last stage.Seven of nine biodiversity indices (Margalef's,IE,Shannon-Wiener,Simpson's,McNaughton's,Species and Odds Measure of Diversity)showed their failure to represent the eutrophication trend,and the other two indices(Menhinick's and Monk)exhibited good efficiency to indicate the eutrophication trend for the static landscaping water body.
