Other Abstract

Geological hazards risk zonation at small watershed scale in seismic disturbed area mainly involves two issues. One is about the difference between the hazards in the small watershed of seismic disturbed area with them in the normal place. The other is about the difference between the geological hazards risk zonation in the particularenvironment with the general area. We discussed landslide and debris flow risk zonation of Baishahe watershed in Wenchuan Earthquake disturbed region according to these two key issues. It considered that landslide and debris flow distributed more largely and widely in a separatedgeomorphological unit of small watershed than in the none-seismic area. They would occur in a higherfrequency and have more potential hazards in the rainfall condition especially. So,in the stage of hazard zonation,it should combine with the seismic factors,evaluate the correlation with them,and highlight the damage effect of seismic vibration. Vulnerability zonation should consider hazard bearing body’s seismic factors. However,risk zonation model is consistent with general area evaluation model,only considering the seismic factors in the hazard zonation stage.
