 “5·12”  Wenchuan earthquake triggered a large number of landslides. A spatial database was developed and analyzed using ALOS satellite imagery and GIS within the Mianyuan River basin. It was indicated that the spatial distribution of earthquake-triggering landslides was dominated by the seismogenic fault. Owing to the duel effect of Yingxiu-Beichuan fault and Jiangyou-Guanxian fault, the landslides were mainly distributed in the hanging wall of two faults. The lithology of stratum determined the type of landslides.  Most landslides occurred within the elevation range from 1 000 to 2 000 m above sea level. Gradient was one of the main controlling factors of landslide distribution.
