摘　　要：海南陵水新村潟湖口外滩槽稳定性差,制约了潟湖的整治和开发利用,为了研究潟湖口外滩槽的演变规律,结合潟湖的地形地貌、海岸动力和泥沙冲淤特点,通过对比潟湖近30 a的遥感影像资料,分析了潟湖口外海岸线、浅滩及深槽的冲淤变化,研究表明潟湖口外潮汐汊道深槽主轴线不稳定,周围岸滩亦存在强烈的冲淤变化,滩槽地貌一直处于单通道和双通道的相互演变之中,一个相对完整的演变期大约需要经历10~20 a左右的时间,波流作用下自东向西的沿岸输沙以及台风等极端事件影响是造成滩槽变化的重要原因。The poor stability of the shoal-channel outside the Lingshui Xincun lagoon estuary in Hainan restricts the regulation,development and utilization of the lagoon.In order to study the evolution characteristics of the shoal-channel outside of the lagoon estuary,combined with the topography and geomorphology,coastal dynamics and sediment transportation of the lagoon,compared the remote sensing image data of the lagoon in the past 30 years,the silting changes of the coastline,shoals and deep channel outside the lagoon estuary were analyzed.The study shows that the main axis of the deep channel of the tidal inlet outside the lagoon estuary is unstable,and there are also strong erosion and sedimentation changes in the surrounding shoals.The shoal-channel landform has been in the mutual evolution of single channel and double channel,a relatively complete evolution period takes about 10 to 20 years.The coastal sand transport from east to west under the action of wave and flow,and the impact of extreme events such as typhoons are important reasons for the changes of shoal-channel.
