摘  要：
以滇西北高原的剑湖茭草湿地湖滨带作为研究对象,通过对生活污水纳污河流-永丰河,农业面源污染纳污河流-金龙河和面山泥沙地表径流汇集河流-格美江河口的茭草湿地湖滨带迎水面和背水面采样监测分析,研究湖滨带对入湖泥沙的拦截效果。结果表明,剑湖茭草湿地湖滨带对各入湖河流泥沙拦截效果较好,且夏秋季节的拦截效果为冬春季节的2~4倍。同时,剑湖茭草湿地湖滨带通过对入湖泥沙的拦截作用能有效减少外源氮、磷污染物进入水体,从而达到对剑湖水环境保护的作用。

摘  要：
Take the plateau Jianhu zizania latifolia wetland lakeside zone of Yunnan north-west region as the object,the field sampling at both front and back of lakeside zone of the sewage polluted river Yongfeng river,agricultural polluted river Jinlong river and collection of surface runoff mountain sediment river Gemeijiang river were surveyed.The results showed the located Lake Jianhu Zizania latifolia lakeside zone had remarkable reduction efficiency for sandy sludge,the reduction efficiency of sandy sludge in summer and failing seasons was 2～4 times than in winter and spring seasons.Simultaneously,through the sandy sludge reduction,the lakeside zone could also reduce the nitrogen and phosphorus into the lake which had effective function for Lake Jianhu water environment protection.
