摘　　要：为了解长江三角洲南汇嘴自然岸线近期生态环境状况,收集了2021~2022年南汇嘴潮滩的卫星遥感数据及历史资料,并结合现场潮间带底栖生物、底质样及水质样的调查数据进行分析。结果表明:南汇嘴自然岸线区域潮间带底栖生物种类总体平稳,沉积物环境相对较好,但植被生长区域受外来物种入侵严重,水环境状态持续较差。外来物种入侵、岸滩侵蚀、旅游活动、海洋垃圾及污染物影响等因素成为该区域主要威胁。针对上述南汇嘴自然岸线现状及威胁因素提出了保护与利用措施。研究成果可为构建合理的自然岸线格局提供科学依据。The coastline is the intersection of land and sea that combines ecological functions and resource value.To understand the recent ecological environment status of the natural coastline of Nanhui Spit in the Yangtze River Delta,the satellite remote sensing data and historical data of the tidal flat of Nanhui Spit,as well as the survey data of benthos samples,sediment samples and water quality samples in the intertidal zone from 2021 to 2022 were collected for comparative analysis.The results indicated that in the intertidal zone,the biological species were generally stable,and the sediment environment was relatively good.However the vegetation growth area was severely invaded by foreign species,and the water environment was in poor condition.The invasion of alien species,beach erosion,tourism activities,marine debris,and the impact of pollutants were the main threats.Finally,the measures and suggestions for protection and utilization was proposed.The research results can providing a scientific basis for constructing a reasonable natural shoreline pattern.
