Application of Extension Theory to the Strategic Decision for Predicting and Mitignting Debris Flow Disasters
可拓学在泥石流预报减灾决策上的应用

According to extension theory,probability theory and the knowledge on debris flow, a pattern of strategic decision with two gradations for predicting and mitigating debris flow disasters is presented in this paper.First, the uncertain factors in debris flow forecast are discussed.Then, using dependent function,a method to determine the bias towards the standard of measures for disaster reduction is introduced.Finally, the matter element model of decision making is established.
