Abstract: Through the field research and remote sensing image analysis of the geological hazards, such as the coseismic collapse ahd the landslide of Tongkou River watershed which was triggered by Wenchuan Earthquake, the spacial geo-hazard distribution in Tongkou River watershed was acquired. Further, analysis is made on the tectonic, landforms and climate factors of Tongkou River watershed, and the following conclusions can be drawn: (1) tectonic factor (Wenchuan Earthquake) is the root cause of the coseismic geological hazards in Tongkou River watershed; (2) the ;andforms factor is one of important environment conditions to the occurring of coseismic and aftequake geological hazards; (3) climate factor(mainly Rainfall) is the direct triggering factor which leaded to the occurring of geological hazards in Tongkou river watershed.
