The paper introduces disaster entropy based on the theory of information entropy and assesses the uncertainty on the disaster occurrence. The theory of information entropy is used for making certain of the uncertainty of the information datum, just like the theory of information entropy, the disaster entropy is used for making certain the importance sectors on disaster incidents and build the calculation model about the quantity of disaster information. Based on many years statistical datum on sand disaster in five different regions (that is Jinhe, Dabanchen, Hami, Trupan, Shanshan) in Xinjiang the paper calculates the frequency of sand disaster and the disaster entropy and make some analysis on the results. It shows that the value of the total disaster entropy in Hami is the biggest and that in Dabanchen is the smallest, the difference in the entropy value between Hami and Dabanchen could reach 7.73. This result also shows that the disaster sectors in Hami region are not only bigger than that of other regions in number but also much great than in other regions in intensity. It makes certain the degree of disaster intensity in quantity and shows whether sectors resulting to disaster is few or not in quality by applying the model of disaster entropy. As a conclusion, the paper also discusses something about the usage on the disaster entropy. The paper put forward zero-disaster phenomenon and conclude this phenomenon into the calculation on the disaster entropy. As a parameter function, the choice about W(P i) is important. At present, the definition of this parameter function adopts two solutions:the first is provided by experts on disaster while the second is obtained by the division on statistical datum.

以信息熵原理为基础 ,引入灾害熵概念 ,评价自然灾害的发生的不确定性和根据各致灾因子的强弱 ,确定灾害事件的重要性因子 ,构建灾害信息量计算模型。并以新疆境内达坂城、精河、哈密、吐鲁番、鄯善等五个地区的多年沙尘暴灾害统计数据为研究实例 ,计算分析了灾害次数、灾害熵。经过分析得出 :哈密地区的沙尘暴灾害不仅灾害强度最烈 ,致灾因子亦最为活跃。通过应用灾害熵及其相应的修正模型 ,可以定量的确定灾害的影响强度 ,定性地说明致灾因子的多寡
