Huizhou Xihu Lake is a shallow city lake. Using the previous research data and preset data, we calculated Carlson trophic state index(TSI)in Xihu Lake. Results of the study show that Xihu Lake was hypereuthrophic, but the present water quality is better than several years ago. Some countermeasure should be adopted such as enforcing non-point pollution control, Xihu Lake aquatic ecosystem restoration.
