Abstract:

Aim of this study was to provide a scientific basis for ecological environmental assessment and comprehensive management of water quality in urban lakes. Field experiment was carried out in Tiande Lake, Taizhou City, Jiangsu Province from Dec 2014 to Jun 2015. The total nitrogen (TN), total phosphorus (TP), transparence (SD), permanganate index (CODMn) and chlorophyll (Chla) were monitored and evaluated by using comprehensive nutrition status index in this paper. The results showed the average content of TN was 0.499 mg•L-1,TP was 0.067 mg•L-1, CODMn was 5.756 mg•L-1, Chla was 11.78 μg•L-1, transparence was 0.65 m. TN, CODMn accord with standard of surface water quality of China Ⅲ class, while TP was Ⅳ class. The comprehensive nutrition state index (TLI(Σ)) range from 45.3 to 55.43 with average of 49.38, the lake belongs to mesotrophic waters, close to eutrophication. The eutrophication prevention measure was put forward.
