摘　　要：1718年通渭7.8级大地震和1920年海原8.5级大地震分别在通渭县境内诱发了大量的黄土地震滑坡,本文通过野外现场调查及遥感解译等手段,对县区内的80处黄土地震滑坡进行了分析研究。得到了研究区地震滑坡的空间及变形分布特征,并对滑坡形成的内、外在影响因素及机理进行探讨分析。根据本文的研究成果,对通渭县区城镇化建设提供参考建议。1718 Tongwei 7. 8 Earthquake and 1920 Haiyuan 8. 5 Earthquake had induced a large number of loess seismic landslides in Tongwei county. Based on the field investigation and Google Earth image interpretation method,we have studied about 80 loess seismic landslides in the county area. Obtain the spatial and deformation distribution characteristics of loess seismic landslides in study area and analyzed the Internal,external influence factors and mechanism of landslide formation. According to the research results of this paper,putting forward some suggestions for project location,road planning and disaster prevention in the Tongwei County.
