高原湿地剑湖湖滨带对水质影响的定量研究

摘要

采用野外采样与室内分析的方法，定量研究剑湖湖滨带对水质的影响作用。结果表明，湖滨带对入湖水流的净化作用效果显著，特别是对水中总氮与总磷的平均除去率高达66．28％和45．73％。同时，湖滨带能有效地拦截水中的泥沙，经测定，湖滨带迎水面的泥层平均厚度是背水面的1．5倍。因此，要重视并保护湖滨带，从而使其功能得到有效发挥。%Quantificationally research on the effects of lakeside in water quality of Jianhu wetland. The results show that the wetland, which makes total nitrogen and total phosphorus reduce by 66.28 % and 45.73 %, can purify water and eliminate bedload effectively. Owing to the function of lakeside, the thickness of mud in area of head-on water is 1.5 times of that in rear water. Accordingly, we should pay more attention to protect the lakeside in order to make it exert its function.
