Aquatic species and population in Chenghai Lake had been dramatically changed in recent two decades. Coverage percentage of aquatic vegetation had varied from a range of 24%-75% to that of 0.2%-85%; and its maximum distribution depth had increased from 4.5m to 5.5m; but the corresponding coverage area had been shrunk from 527.8hm2 to 73.05hm2;  the resource storage had reduced from 4766 tons to 314.53 tons. Analysis indicates that destruction of suitable habitat in southern part of the lake, pollution, eutrophication and unreasonable stocking grass carp were the main reasons causing the remarkable decay of aquatic vegetation. Protective measures had been proposed based on wetland restoration in southern part, pollutant reduction, prohibition of stocking grass carp, and control over pollution and eutrophication.

Key words: Aquatic vegetation, Status, Evolution trend, Chenghai lake
