象湖湿地敏感区修复工程效果研究

The Preliminary Evaluation of the Effect of Restoration Project in the Sensitive Area of Xianghu Wetland

该文应用模糊综合评价法对南昌市象湖湿地敏感区湖泊湿地在修复工程前后的水环境因子进行综合评价.研究结果表明:在修复工程前,象湖水质为Ⅴ类水和劣Ⅴ类水;在修复工程后,象湖湖体水质为Ⅴ类水,象湖滚水坝水质为Ⅱ类水,木桩驳岸水质为Ⅵ类水,其中在大部分水体中的COD、TN、TP含量都有明显改善,这说明象湖修复工程对水质有较明显的净化作用.在象湖修复工程之后,象湖湿地土壤的pH值由偏酸性向中性转变,含水量增加,更加适合植物生长.

The fuzzy comprehensive evaluation method is used to comprehensively evaluate the water environment factors of the lake wetland in sensitive area after the restoration project.At the same time the water quality indicators and the physical and chemical properties of the soil are compared before and after the restoration project.The results show that before the restoration project,the water quality of Xianghu Lake is Class V or worse than Class V.After the restoration project,the water quality of Xianghu Lake is Class V,the water quality of Xianghu Rolling Dam is Class II,and the water quality of the Stake Piles is Class VI,the content of COD,TN,TP in most of the water bodies has been significantly improved,indicating that the Xianghu Project has an obvious purification effect on water quality.After the Xianghu Lake restoration project,the pH of the Xianghu wetland soil changes from acidic to neutral,and the water content increases,making it more suitable for plant growth.
