Abstract:
Cuihu Lake in Kunming City is a plateau lake recharged by reclaimed water. Based on four periods of week2long diurnal monitoring water quality data in Cuihu Lake from May to October in 2013, the spatial and temporal distributions of water trans2 parency and the relationship between transparency and T ( water temperature), pH, DO, Chla ( Chlorophyll a) , TP, SS, COD Cr , N/ P, TN, NH 4 2N, DTP, and DTN were analyzed. Additionally, SD was considered as the dependent variable, multiple regression analysis was conducted for each water environment factor. The results indicated that the water transparency in Cuihu Lake is lower in the western area (averaged 33. 6 cm, with deeper water and fewer aquatic plants) and higher in the eastern area (aver2 aged 61. 5 cm, with more aquatic plants and better water quality). The correlation analysis and multiple regression analysis showed that water transparency is negatively correlated with T, pH, DO, Chla, TP, SS, and COD Cr ( p< 0. 01) , and positively cor2 related with N/ P and T N ( p< 0. 01) . Chla is the primary and important factor affecting water transparency in Cuihu Lake, and COD Cr , TP are two significant water quality factors to impact the algae growth in Cuihu Lake. The research results can provide scientific reference for the improvement of water transparency and landscape value in plateau lake recharged by reclaimed water.
