| 摘要: |
| 文章通过对82个海岛地质灾害普查资料分析，总结了我国典型海岛的主要地质灾害类型和分布特征。我国海岛主要存在滑坡、海岸侵蚀、海水入侵、湿地退化、水土流失、沙滩泥化等多种地质灾害类型，其中以滑坡、海岸侵蚀、海水入侵和滨海湿地退化最为典型,分布较广。针对海岛主要地质灾害提出了滑坡崩塌、海岸侵蚀、海水入侵、滨海湿地退化等具体的防治措施，这样有利于海岛资源和环境的保护，也可为海岛防灾减灾提供理论支持。 |

| Abstract: |
| Based on the survey data of 82 islands，the main geological disaster types and distribution characteristics of typical islands in China were summarized.There are many types of geological disasters in islands,such as landslides,coastal erosion,saltwater intrusion and coastal wetland degradation，beach surface erosion,beach mudding,et al.Landslides,coastal erosion,saltwater intrusion and coastal wetland degradation are very typical and widely distributed.According to the main geological disasters of island,some specific measures were put forward,such as preventing landslides and collapses,coastal erosion,saltwater intrusion and coastal wetland degradation,which would be beneficial to the protection of the island resources and environment,and provide theoretical support for the disaster prevention and reduction of island. |
| Key words: Islands,Geological disasters,Coastal erosion,Saltwater intrusion,Ecological environment,Preventive measures |
