中文摘要：海南岛海岸以岬湾海滩为主,是我国重要的滨海旅游目的地,也是裂流引起滨海溺水事故的高发地。为研究海南岛岬湾海滩裂流的分布特征,从海南环岛54个岬湾海滩近20年的卫星影像中解译裂流的发生情况,统计裂流的分布特征,并与现场调查结果对比。结果表明:在区域分布上,海南岛东岸和南岸岬湾的裂流发生率明显大于西岸和北岸;在位置分布上,岬湾中部的海滩裂流数量高于两侧;在几何特征上,裂流的平均长度与平均宽度、平均间距均呈正相关,但裂流的平均宽度、平均数量与裂流间距均无显著相关性。波浪环境对裂流密度影响明显,表现为裂流密度随平均有效波高、平均波周期、平均入射波功率和平均入射波能的增加均减小。岬湾尺度对裂流发生数量影响明显,表现为岬湾宽度、岬湾凹入度和岬角长度与平均裂流数量均呈正相关,但岸线曲率与平均裂流数量无显著相关性。卫星影像解译裂流发生情况与现场调查结果和裂流风险评价模型的结果基本一致,相关结论可为海南岛海滩安全管理和裂流预警工作提供参考。

外文摘要：The coast of Hainan Island is dominated by embayed beaches,which is an important coastal tourist des-tination in China and also has a high incidence of drowning accidents caused by rip currents.To investigate the dis-tribution characteristics of rip currents on embayed beaches,the occurrence and distribution characteristics of rip currents are interpreted from the satellite images of 54 embayed beaches around Hainan Island over the past 20 years,and compared with the field survey results.The results show that,in terms of regional distribution,the occur-rence probability of rip currents on the eastern and southern coasts is significantly higher than that on the western and northern coasts of Hainan Island.In terms of location distribution,the number of rip currents in the middle of the headland bays is higher than that on the two sides.In terms of geometric characteristics,the average rip length was positively correlated with the average rip width,and the average rip spacing.The distribution density of rip cur-rents is negatively correlated with significant wave height,average wave period,incident wave power,and wave en-ergy.The scale of the headland has a significant effect on the number of rips,which is positively correlated with the bay width,the maximum bay indentation,and length of the headland,but the curvature of the shoreline has no signi-ficant correlation with the average number of rips.The results of satellite image interpretation for the occurrence of rips are consistent with the results of the field survey and the evaluation of theΩ-RTR model.These conclusions can provide useful references for the beach safety management and rip current warning work on Hainan Island.
