摘要
通过对城市浅水型湖泊 (以南京玄武湖为例 )底泥磷释放特性进行实验研究 ,分析了环境因子对底泥磷释放特性的影响及其原因。得出了溶解氧、pH值、温度和扰动对底泥磷释放的影响曲线。同时说明了湖泊内源性磷对湖泊水质存在着潜在的危险性 ,为城市浅水型湖泊底泥疏浚和富营养化治理提供依据。
Experiments are conducted to study phosphate released from sediments in Xuanwu Lake, an urban shallow lake in Nanjing. Ambient factors such as DO, pH, temperature and disturbance are evaluated for their effects on phosphate release. It is shown that internal loading greatly menaces lake water quality.
