摘要：

The occurrence of debris flow is affected by many factors.Risk zoning of debris flow plays a vital role in the early-warning and prediction of abrupt geological hazards,and exploration of new method is needed in the early-warning and prediction of geological hazards.The extension theory is a new method to solve contradiction matters.Based on extension theory,AHP and GIS,the risk zoning model of debris flow was established in this paper.The result of this research provides a new way in the risk zoning,early-warning and prediction of debris flow
