摘　　要：根据山区灾害多发区段线路方案优选问题具有多因素和模糊性的特点,在建立多级模糊综合评价的指标体系的基础上,采用层次分析法合理确定路线方案各影响因素及其各子因素的权重,运用模糊数学理论,建立了山区灾害多发区段路线方案的二级模糊综合评选的数学模型,提高了山区灾害多发区段路线方案评选的客观性和科学性.并以山地灾害多发的迫隆藏布流域段为实例进行了研究,证明了这种方法的合理性和有效性.In mountain hazardous areas, being aimed at the characters of many complicated factors and fuzzification in road optimization planning, based on establishing the index system of the two-stayed comprehensive fuzzy assessment, the rights of the first and secondary influence factors are reasonanbly determined through Analytic Hierachy Process, and then, a two-stayed fuzzy assessment model for selecting the route plan is established by using the theory of fuzzy methematics, and improves the scientific character and the objectivity of selecting the route plan in mountain hazardous areas. At last, use polongzangbu basin as a example demonstrate the rationality and validity of the model.
