中文摘要：

地震地质灾害发育特征及主控因素分析是科技防灾减灾领域研究的重要内容.笔者在2013年甘肃岷县-漳县地震区现场调查的基础上,分析了地震诱发崩塌滑坡泥石流等地质灾害的类型、空间分布和典型灾害体特征,研究了本次地震的发震构造与灾害点的关系.取得了以下主要认识：1）岷县-漳县地震诱发的地质灾害类型主要为小型、中型的黄土崩塌和滑坡,地质灾害总体表现为数量多、分布广,与发震断裂和水系关系密切,滑坡灾害危害严重;2）地质灾害分布密集区与地震烈度的极震区基本吻合,且地形坡度为10＆#176;～30＆#176;的范围内与地貌高程2000～3000m的范围内地质灾害分布最为密集,它们的灾害数量分别占震区地质灾害总数的70.1％和84.4％;3）震区崩塌滑坡泥石流灾害的总体展布特征受控于NW向的韩家山-梅川镇断裂,其是NWW临潭-宕昌断裂的分支断裂.

英文摘要：

The developmental characteristics of geohazards induced by earthquake and causative tectonics are important issues of scientific and technological research fields for geohazards prevention and mitigation. In this paper, based on the field survey of the area influenced by the Minxian-Zhangxian Ms6.6 earthquake on 22 July, 2013, Gansu Province, China, the types, spatial distribution characteristics and typical cases of geohazards are investigated, and the causative tectonics in the region were also analyzed. Some conclusions are obtained： 1） The scales of loess collapses and landslides induced by the earthquake are mainly small and medium, and the number of geohazards distributed widely after the earthquake. The geohazards induced by the earthquake are concentrated in two belts： one is along seismogenic fault, and the other is along the Tao River and within 1.5km distance from the river; 2） The geohazards concentrated areas are closely coincides with the meizoseismal area and mainly distributed in terrains slope of 10°-30° and geomorphology elevation of 2000-3000m, and the ratios of geohazards in these two kinds of the total number of geohazards in the study area are 70.1% and 84.4% respectively; 3） The causative tectonics of the Minxian-Zhangxian earthquake is likely the secondary branch faults of the Lintan-Tanchang Fault, which is the Hanjiashan-Meichuan Fault, the centralized areas distribution of geohazards are controlled by the Hanjiashan-Meichuan Fault, and the key triggering factors of Baozi large scale landslide and the Wamuchi large scale landslide are the NE secondary faults of the Lintan-Tanchang Fault.
