中文摘要：

对金沙江上游特米大型古滑坡的成因及古地震参数反分析进行研究。在野外详细地质地貌调查及14C年代测定的基础上，确定特米大型古滑坡是由地震触发形成，滑坡曾形成堰塞坝堵塞了金沙江，其形成时间约为7210BP。基于Newmark法分析了触发特米古滑坡的地震震级与震中距之间的关系，结合地质地貌调查，初步推断地震震中位于特米滑坡下游雄松一苏哇龙活动断裂上（栋索到拉扎西段），地震震级为7．0～7．4级。

英文摘要：

The formation mechanism of Temi large-scale ancient landslide in the upper Jinsha River and back analysis of paleoseismic parameters was studied. Based on field geological and geomorphological investigation and 14C dating, we determined the Temi large-scale ancient landslide was triggered by earthquake, it had formed the landslide dam and blocked the Jinshajiang River at around 7 210 BP. Then the relationship between magnitude of earthquake that induced Temi large-scale ancient landslide and epicenter distance was analyzed by Newmark method. Combined with geological and geomorphological surveys, we preliminary concluded that the epicenter of the earthquake was located at the Xiongsong-Suwalong active fault of the downstream of the Temi landslide （ Dongsuo to Lazhazi section）, and the magnitude of it is 7.0 - 7.4.
