摘　　要：台西南盆地是南海北部陆架台边缘含油气盆地之一，在未来的油气勘探与开发中，面临着海洋地质灾害的威胁。利用地震等地球物理资料及区域天然地震地质资料的综合研究，初步研究了盆地中地质灾害因素的主要类型（断层、天然地震、海底地形障碍、海底滑坡、火山活动等），研究了不同类型地质灾害的活动规律、分布位置和主要成因。认为区内地质灾害因素的发生发展与欧亚板块与菲律宾板块的碰撞有关。同时还讨论了地质灾害与海洋环境的关系，认为它们是密不可分的环境系统。为了防止海洋地质灾害的发生，建议研究区内的新构造运动，并尽快尽早开展区内的海洋地质灾害和海洋工程地质调查。Southwest Taiwan basin is located in the shelf margin of northern part of South China Sea. It is one of the petroliferous basins. However, it is faced with potential marine geohazards in future petroleum exploration and development. According to seismic, regional earthquake and geological data, the paper discusses the main types of geohazards (faults, earthquakes, seafloor slip and sea floor topographial obstacles), activities, distribution and causes of these geohazards. It concludes that the geohazard are related to the collision of Euro-Asin plate and Philippine plat. It also discusses the relation between geohazards and marine environment, indicating an integral environmental system. For the purpose of preventing marine geohazards, it is suggested that a study should be Carried out on new tectonics in the study area and survey should be started as soon as possible for marine geohazards and engineering geology in the area.
