摘要：

采用野外采样与室内分析的方法，从水质和底泥两个方面定量研究剑湖湖滨带的功能作用。结果表明，湖滨带在水质净化和拦截泥沙等方面效果显著，特别是对水中总氮与总磷的平均去除率分别高达66.28%和45.73%，其拦截作用表现为：迎水面的泥层厚度是背水面的1.5倍；底泥的各项指标(除pH值)，湖滨带背水面均比迎水面高，速效磷和全氮的增加量最为明显，其含量分别是迎水面的3.30和2.61倍，这主要与湖滨植物带大量吸收入湖矿质营养用于自身生长，其残体在背水面沉积有关，从另一角度体现了湖滨带的吸附、净化功能。因此，要重视并保护湖滨带，从而使其功能得到有效发挥。

Abstract:

Wetland lakeside function of Jianhu Lake is qualitatively studied by indexes of water quality and sediment,through field samples and data analysis. It is showed that wetland lakeside plays an important role in water quality purification and intercepting sediment,among which the average evisceration rate of total nitrogen and total phosphorus are 66.28% and 45.73% respectively. Results of interception are as followings: （1） the thickness of mud in upstream face is 1.5 times than that in downstream face;（2） except for pH,all indexes of mud in downstream face are more than that in upstream face,among which the available phosphorus and the total nitrogen in downstream face are 3.30 and 2.6 times than that in upstream face respectively,where vegetation absorbs much mineral nutrition and their remains are accumulated. It could be concluded that lakeside has absorption and purification functions. Therefore it is necessary to protect lakeside so as to effectively exert their functions.
