| Abstract: | This paper summarizes water physicochemieal characteristics during April, July and October of 2009 in Chuyun Lake. The result showed ： Water temperature was 20.5 ℃. seeehi transparency was 48.2 cm, pH value was 7.09, alkalinity was 1.47mmol/L, dissolved oxygen was 5.19mg/L, chemical oxygen demand was 4.02 mg/L. The content of nitrogen was 0. 010 in Chuyun Lake. There were marked seasonal changes in most physicochemical components in the water. The differences of most physicochemical components were inconspicuous in horizontal an distributions. The content of COD and DO in water of Chuyun Lake is more than that of the Ⅲ class water. |
