摘　　要：采用野外采样与室内分析的方法,探讨剑湖入湖河流廊道及其湖滨带对城镇生活污水的净化效果。结果表明:自然河道和湖滨带在水质净化方面效果显著,自然河道对COD、总磷、总氮和氨氮的去除率分别为53.4%、38.4%、31.6%和44.7%,湖滨带对总磷、总氮和氨氮的去除率分别高达67.7%、58.4%和62.1%,水质得到极大改善。可见,自然河道及湖滨带对城镇生活污水的净化效果显著,对剑湖湿地生态系统稳定性具有重要作用。The purification effects of river corridor and lakeside zone of Jianhu Wetland on the municipal domestic sewage were studied by the field sampling and laboratory analysis.The resluts showed that the purification effects of natural bank and lakeside zone were significant.The removal rates of of COD,TP,TN and NH4＋-N by the natural bank were 53.4%,38.4%,31.6% and 44.7%,respectively,and the water quality was improved greatly,which indicated that the natural bank and lakeside zone played important roles in purifying the municipal domestic sewage and maintaining the stability of Jianhu Wetland ecosystems.
