| 摘要: |
| 长江口南汇地区兼具河口三角洲和海洋湾区的地理特征，近年来该区域新发育的海滩已成 为上海市市民最热门的亲海空间之一。文章通过收集地形数据、卫星遥感数据及相关文献资料 等， 研究了南汇海滩当前存在的问题， 并提出了滩涂湿地的长效保护策略及亲海空间拓展建议， 具体如下：（1）南汇海滩近年来存在海岸侵蚀、互花米草入侵等灾害风险，局部存在离岸流分布；
（2）目前上海临港滨海生态保护修复工程已经成功遏制南汇海滩的持续侵蚀趋势，并彻底清除了互花米草；（3）拟定了南汇海滩智能化管理措施，并提出了南汇海滩数字化底座和智慧管理措施建议；（4）建议将南汇海滩建成海洋公园，整体可规划为滩涂保护区、内湖湿地区、科普廊道、亲海游憩区，并根据离岸流分布区划定了安全游憩红线。 |

| Abstract: |
| The Nanhui area at the mouth of the Yangtze River exhibits geographical characteristics of both an estuarine delta and a marine bay．In recent years，newly formed shoals in this region have become one of the most popular coastal recreation spaces for residents of Shanghai．By collecting topographic data，satellite remote sensing imagery，and relevant literature，this study investigates current challenges facing the Nanhui shoal and proposes long-term conservation strategies for tidal flats and wetlands，along with recommendations for expanding public access to coastal areas．The main findings are as follows：（1）In recent years，the Nanhui shoal has faced multiple hazards，including coastal erosion，invasion by Spartina alterniflora (smooth cordgrass)，and localized rip current occurrences．
（2）The Lingang Coastal Ecological Protection and Restoration Project in Shanghai has successfully curbed ongoing beach erosion and completely eradicated Spartina alterniflora from the area．（3）Intelligent management measures for the Nanhui shoal have been formulated，including proposals for establishing a digital foundation and implementing smart management systems．（4）It is recommended that the Nanhui shoal be developed into a marine park，with integrated zoning comprising a tidal flat conservation area，an inland lake wetland zone，an science popularization corridor，and a coastal recreation area．Additionally，safety boundaries for recreational activities have been delineated based on identified rip current zones. |
