摘　　要：构建了水库下游居民风险承受能力指标体系,采用熵权系数法对风险承受能力进行模糊综合评价。结合陕西省西安市石砭峪水库下游居民调查实例,通过熵权系数法对各评价指标赋值,利用加权平均模糊合成算子得出评价结论,调查地区水库下游居民风险承受能力等级为"中",针对评价结果给出了提高水库下游居民风险承受能力的具体建议。This paper constructed the evaluating index system of risk bearing capability. According to the characteristics of fuzzy, the fuzzy comprehensive evaluation is applied in the risk bearing capability of resident in dam downstream region and surveyed the questionnaires in downstream region of Shibianyu Dam ih Xi＇an, Shanxi province. The evaluation of the weighting sets are made by entropy weight coefficient method. Using fuzzy weighted average method, the evaluation result is taken as ＂middling＂. In light of the case, specific measures are proposed to improve the risk hearing capability of resident in dam downstream region.
