摘　　要：通过资料收集和野外踏勘,统计分析了海南岛海岸带发育的各种地质灾害,主要的地质灾害类型有地震、活动断裂、海岸侵蚀、土地盐渍化、土地荒漠化、水土流失、河口港湾淤积、崩塌、滑坡等。控制研究区各类地质灾害发生的因素有构造、坡地重力、水动力、地下水和风力等5种,其中水土流失的控制因素既有水动力因素也有风力因素。在此基础上编制了海南岛海岸带地质灾害分布图,分析了各种地质灾害发生的空间特征及形成灾害的主要因素,为防灾减灾提供了决策依据。By data collection and field reconnaissance,we analyze all kinds of the geological hazards statistically which exist in the coastal area of Hainan Island.The main types of geological hazards are earthquake,active fault,coastal erosion,soil salinization,land desertification,soil erosion,estuary and harbour silting,collapse,slide,et al.The controlling factors of the local geological hazards are：tectonism,slope gravity,hydrodynamic force,ground water and wind power.The soil erosion can be caused by either water power or wind power.The distribution map of geological hazards is compiled for the area,and the spatial features and the main causing-hazard factors are studied.The research provides a decision-making basis for prevention and mitigation of the hazards.
