Abstract: Using the method of trophic state-composite index ( TSI-CI ) and the 12 months of monitoring data in 2010, we carry out initial exploration of the status of ecosystem health in Wuli Lake. First, we select four indicators, Chla, SD, TP and TN, to conduct trophic state assessment using weighted index method; then after selecting physical, chemical and biological indicators to conduct nondimensionalization processing, we calculate the composite index and conduct comprehensive assessment. The results show that in 2010, the status of ecosystem health in Wuli Lake was the best in July, worst in August; when the composite trophic state indicators with Chla as the representative increase or decrease significantly and cross different nutritional grades, TSI will significantly deviate from CI, and the relationship between the two in the other time is not prominent.
