中文摘要	分析了现行泥石流危险性评价方法在因子选择、权重确定、危险度计算、区划原则和区划结果等方面存在的问题，提出对泥石流危险性应进行三个层次的评价：泥石流存在环境的质量评价、泥石流活动性的评价和泥石流破坏能力的评价，并以势函数定义了泥石流危险度的统一形式，它可以满足不同目的的危险性评价

In conclusion , a new recognition of the assessment of risk of debris flow arises ,suggest2ing a assessment system , consisting of valuation of environment quality , of debris flow activity and violability , to clarify the above uncertainty by imposing rest rictions on the action of each factor. In other words , the action of a certain factor will be distinguished by specified purpose. Regarding all the quantities to be valuated as a special form of a general function , i. e. , the potentiality φ, we suppose a universal definition of the magnitude of degree , D = D0 + kln φ which will be applicable to assessment s of any purpose and overcome the problems present in the current assessing programs.
