摘要 目的 采用模糊信息扩散法对广西大石山区干旱灾害风险进行评估与区划为该区干旱灾害风险
管理提供参考 方法 在信息不完备情况下采用能表达概率估计模糊不确定性的信息扩散法在不假定概率分布
的情况下对广西大石山区农业干旱灾害损失风险及因旱人饮困难风险进行评估绘制其区划图并将分析结果与近
年的实际干旱灾害发生情况进行比对 结果 基于信息扩散法的广西大石山区干旱灾害风险评估结果与近
年历史实际干旱灾害调查结果基本吻合表明用信息扩散法进行区域干旱风险评估是可行的 结论 在信息不完
备的条件下用模糊信息扩散法进行干旱灾害风险评价和区划可得到更为准确的结果
关键词风险管理信息扩散风险评估区划

Abstract Objective Fuzzy informational diffusion method was used to carry out the assessment and region
alization for drought disaster risk of Dashishan region in Guangxi province to provide more reference for the drought
disaster riskMethod Under the case of incomplete informationthe informational diffusion method which can ex
press the fuzzy uncertainty of probability estimates is used to assess the agricultural and peoples drink difficulty
drought risks and draw zoning map of the Dashishan region in Guangxi provinceWithout assuming the probability
distribution in advancethe calculation results are taken to compare with the actual history drought disaster investi
gating results of the past yearsResult The drought disaster risk assessment results of Dashishan region in
Guangxi province based on information diffusion method are basically consistent with the actual history drought dis
aster investigating situation of the past yearswhich shows that the informational diffusion method to regional
drought risk assessment is feasibleConclusion Under the condition of incomplete informationfuzzy informational
diffusion method for the drought disaster risk assessment and regionalization can obtain more accurate results
