南京市河流湿地生态健康评价与生态对策研究——以绿水湾湿地为例

Ecological Health Assessment and Bionomic Strategies of Riverine Wetlands in Nanjing: A Case Research on the Lvshuiwan Wetland for Order

本文选择南京江北滨江绿水湾湿地作为河流湿地典型研究区,构建湿地生态健康评价指标体系与评价等级。评价结果表明,绿水湾湿地总体处于一般健康水平,内部存在差异。针对湿地健康状况和存在的主要生态环境问题,作者对湿地进行了生态功能区划定并提出相应的生态管控与生态修复基本要求,同时提出了涉及水环境改善、沼泽地恢复等方面的11项具体生态工程,并预评价工程实施后绿水湾湿地的生态健康水平等级有望达到健康水平。

The paper chooses Lvshuiwan wetland along Yangtze River in Jiangbei of Nanjing as a typical study area of riverine wetland. We construct an evaluation index system of wetland ecosystem health and then make a semi-quantitative evaluation of Lvshuiwan wetland ecosystem health. The results show that the overall Lvshuiwan wetland ecosystem health is at an average level, and has internal differences. Aiming at the main problems about wetland degradation such as deterioration of water environment, the paper gives the corresponding ecological counter measures like water purification and cleaning as well as ecological restoration projects like the recovery of marshland.
