摘要
双龙湖是浅水型城市湖泊,在外源污染得到有效控制后,内源污染成为湖泊营养物主要负荷,因此笔者分析了双龙湖底泥释磷影响显著因子(温度、pH、溶解氧、水动力),并用多元回归得出双龙湖底泥平均释磷强度模型:R=0.396+0.0184[T]+0.0589[pH]-0.176[DO]+0.122[K],通过释磷模型预测不同环境条件下底泥释磷规律,从而采取适宜措施抑制磷释放,控制内源污染。
Shuanglong Lake is a shallow lake in the urban city. After the comprehensive harnessing of outside pollutants,the endogenetic pollutants caused by polluted sediments may become the main nutritional loading in the lake. This essay analyzes the effects of marked environmental factors（temperature,pH, DO and water dynamics） on phosphorus releasing and calculates the releasing formulation： R=0. 396＋0. 0184 [T]q-0. 0589[pH]-0. 176 [DO] ＋ 0. 122[K]. Analysis and estimation of phosphorus releasing of Shuanglong Lake＇s polluted sediments in different conditions can provide us with proper controlling measures.
