摘　　要：根据文成-泰顺地震资料和地震地质灾害应急调查结果,对文成-泰顺地震地质灾害的发育特征进行了总结。结果表明:地震地质灾害具规模小,威胁性大,突发性及隐蔽性等特点,其预防具有一定的难度;通过进一步的成因分析发现,地震地质灾害与地震强度、震中距具有一定的关联性,地震地质灾害随地震震级增大而呈加剧趋势,地震发生后,岩土体变松散,在冰冻、台风、暴雨及长时间的降雨等恶劣环境条件下,后期次生地质灾害呈加剧趋势。本研究可为相关部门编制地震地质灾害规划提供参考,对进一步做好地震地质灾害防治工作具有积极意义。Based on the seismic data and emergency investigation survey of seismogeologic disaster in Wencheng-Taishun, the seismogeologic disaster characteristics of Wencheng-Taishun was summarized.The results show the seismogeologic disaster in Wencheng-Taishun possesses multiple features of small,great threat, abruptness and covertness, which make the disaster hard to prevent. A further analysis on seismogenesis reveals the seismogeologic disaster is relevant to earthquake intensity and epicentral distance, and the disaster becomes heavier as the earthquake magnitude increases. The rock and soil becomes loose after the earthquake, and the secondary geological disasters are more likely to occur under bad weathers, such as freezing weather, typhoon and long- period rainfall. The research provides a reference for the compilation of the seismogeologic disaster planning, and has a great significance on the prevention of the seismogeologic disaster.
