摘　　要：为研究滨水生态驳岸对水体的净化效果,本文以南昌市象湖湿地公园生态驳岸为例,通过重新构建生态驳岸植物群落等工程改造,监测和评价生态驳岸工程改造前后示范段的近岸水体净化效果。结果表明,改造前,区域内各水体的污染程度均较严重,原硬质驳岸、自然缓坡和木桩驳岸的近岸水质均为地表水Ⅴ类或Ⅴ类以下,以总氮为主要污染物,而总磷的污染程度较小。改造完成后,区域内的主要水体水质上升为地表水Ⅲ类,透明度明显增大;仅有局部的微小区域水质仍为Ⅴ类,但其污染指数已有明显降低。因此,生态驳岸的营建和滨水地带植物群落的合理布局,结合污染控制,能够较好地保护和重建水陆边缘地带的自然生态过程及岸栖生物栖息环境,有效地发挥其生态系统边缘效应,形成自然优美、生态功能持续稳定的湖泊湿地景观。In order to study the purification effect of waterfront ecological revetment on water body,taking the ecological revetment of Xianghu Wetland Park in Nanchang City as an example,it was monitored and evaluated the near-shore water purification effect of the demonstration section before and after the ecological revetment project transformation,through reconstruction of ecological revetment plant community.The results showed that,before the renovation,the pollution degree of each water body in the region was relatively severe.The nearshore water quality of the original hard embankment,natural gentle slope,and wooden pile embankment were all Class V or below surface water.Among them,TN was the primary pollutant,while TP had a relatively small degree of pollution.After the renovation was largely completed,the water quality of the main water body in the region was increased to surface water classⅢ,with significantly greater transparency.It was still category V in only small local areas of water quality,but its pollution index had been significantly reduced.Therefore,the construction of ecological barge and the reasonable layout of plant communities in the waterfront area,combined with pollution control,can effectively protect and rebuild the natural ecological processes and habitat environment of shore dwelling organisms in the water land edge zone,effectively play its ecosystem edge effect to form a naturally beautiful and ecologically stable lake wetland landscape.
