| 摘 要： | 海岸潟湖是半封闭系统,往往被海岸沙丘、沙嘴或沙坝阻碍了淡水与海洋的流通,也是重要的栖息地,如湿地、红树林、盐沼和海草地等。在过去的30年,七里海潟湖湿地生态系统遭受了严重的干扰。文章基于1987年、2000年、2010年和2017年的遥感数据,开展了七里海潟湖湿地类型变化研究。结果表明:1987年以来,七里海潟湖湖盆和沼泽面积持续减少,主要原因是向养殖池塘和稻田转变。围堰养殖、稻田开发、渔港及防潮闸建设等导致潟湖淤积严重,湖盆面积萎缩,水质恶化。为了更好地开发和利用潟湖湿地资源,提出了生态修复工程与措施。

| Abstract: | Coastal lagoons are shallow semi enclosed systems where freshwater inflows are trapped behind coastal dune systems,sand spits,or offshore bars which impede exchange with the ocean.Coastal lagoons are also important habitats,such as wetlands,mangroves,salt marshes and seagrass meadows.In last three decades,natural ecosystems in the Qilihai lagoon wetland have undergone significant disturbance.Based on remote sensing data of 1987,2000,2010 and 2017,this paper analyzed the study of dynamic characteristics of landscape metrics in Qilihai lagoon wetland.The wetland area of Qilihai lagoon decreased from 1987,while aquaculture ponds and paddy field increased significantly.The scope of the lagoon wetland and swamp were converted into aquaculture ponds.Due to the construction of cofferdam,paddy field,fishing port and ebb gate,the basin was seriously filled up and withered,and the water quality becomes worse.In order to better develop and utilize the resources of the lagoon wetland,ecological repair strategies and measures were proposed for wetland protection. |
