摘　　要：根据野外调查和航片解译结果，对１９２７ 年古浪８ 级大震产生的主要地质灾害———地震破裂带、滑坡和裂缝及其展布特征进行了描述，并对该次地震的破坏特征及其控制因素进行了探讨．结果表明。Based on field investigations and interpretative result from air photos,the main geological disasters including the seismic rupture zone,the seismic landslides and the seismic fissures,and their distribution of the 1927 Gulang M S8 earthquake are described.Then,the characteristics and controling factors of destruction of this earthquake are studied.The result shows that the surface destruction of the earthquake is obviously affected by the geography and the types of rock and soil.
