英文摘要	The southeastern margin of Qinghai-Tibet Plateau (SMQTP) is of a typical large landslide-prone area due to intense tectonic activity, deeply incised valleys, high geostress and frequent earthquakes. To gain insights into large landslides in southeastern margin of Qinghai-Tibet Plateau, an area covering 3.34 x 10(5) km(2) that extends 80-150 km on both sides of the Sichuan-Tibet traffic corridors (G318) was used to examine the spatial distribution and corresponding characteristics of landslides. The results showed that the study area contains at least 629 large landslides that are mainly concentrated on 7 zones (zones I-VII). Zones I-VII are in the southern section of the Longmenshan fault zone (with no large river) and sections with Dadu River, Jinsha River, Lancang River, Nujiang River and Yarlung Zangbo River. There are more landslides in the Jinsha River section (totaling 186 landslides) than the other sections. According to the updated Varnes classification, 408 large landslides (64.9%) were recognized and divided into 4 major types, i.e. flows (275 cases), slides (58 cases), topples (44 cases) and slope deformations (31 cases). Flows, which consist of rock avalanches and iceerock avalanches, are the most common landslide type. Large landslide triggers (178 events, 28.3%) are also recognized, and earthquakes may be the most common trigger. Due to the limited data, these landslide type classifications and landslide triggers are perhaps immature, and further systematic analysis is needed.
