Research on the purification effect of waterfront ecological revetment on water bodies—taking the Xianghu Wetland Park in Nanchang City as an example
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.
