摘　　要：采用裂流综合风险指数法,通过地形动力分析、遥感影像解译、现场观测调查等多重手段对海南岛沿岸66个重点海水浴场裂流风险进行评估,分析海南岛沿岸裂流分布特征。结果表明:海南岛裂流风险存在明显区域性分布特征;排查出的20个高风险浴场主要分布在东南沿岸的琼海、万宁、陵水和三亚等地,多为沿岸沙坝型海滩,遥感影像显示常年存在沙坝沟槽和裂流现象,这与海南岛东南部的强浪条件有关;西北部潮强浪弱,海滩多为潮控型的平坦消散型海滩,裂流风险相对较低。Rip current comprehensive risk index method is used to assess the risk of rip currents at 66 key bathing beaches along Hainan Island by multiple means,such as morphodynamic beach classification,remote sensing image interpretation,on-site drone observation,dye tracing and visiting and questioning.Totally 20 high-risk bathing beaches are identified,which mainly distributed in the southeastern coastal areas,such as Qionghai,Wanning,Lingshui and Sanya.Most of them are the Barred Beaches with alternating transverse bars and rips all year-round detected from remote sensing imagery,which are related to the strong wave conditions in the southeastern part of Hainan Island.In the northwestern part of the island,the tides are strong,the waves are weak,and the beaches are mostly tide-controlled flat dissipative beaches with relatively low risk of rip currents.
