剑湖湿地湖滨带功能效益研究

通过野外定位采样及室内试验分析,对剑湖湿地湖滨带水质净化作用进行了研究。结果表明:入湖口和湖滨带前端水质的多项指标与湖滨带后端及出水口相比均较高。其中,湖滨带前端总磷、总氮、氨氮的含量分别是湖滨带后端的2.68、3.07、1.43倍。剑湖湿地湖滨带通过水—土壤(沉积物)—植物系统的过滤、渗透、吸收、滞留、沉积等物理、化学和生物功能效应,控制、减少了来自地表径流的溶解性污染物质,达到了降解环境污染、净化剑湖水质的目的,是湿地生态系统的重要组成部分。

Research on the Functions and Benefits of Lakeside Zone in Jianhu Wetland

The clarification of water quality on lakeside zone in Jianhu wetland was researched based on the methods of sample plot survey and experiment analysis.The results showed that the indexes of frontal lakeside zones were higher than those of the backside and outlet.For example,the totle phosphorus of frontal lakeside zones was about 2.68 times more than the end,the total nitrogen was about 3.07 times,the ammonium was about1 43 times.The lakeside zones in Jianhu wetland with the methods of filtration,percolati...
