摘　　要：运用复杂网络的相关理论知识,在冰雪灾害危机事件演化机理研究的基础上对冰雪灾害危机事件演化构成和衍生链特征进行了分析。以2008年冰雪灾害危机事件演化为例将冰雪灾害危机事件演化划分为4种类型,构建了冰雪灾害危机事件演化的网络结构。在此基础上总结了冰雪灾害危机事件衍生链的特征,并对冰雪灾害危机事件演化特征进行了分析,为控制冰雪灾害危机事件的演化提供了理论依据。By using the complex network theory and related knowledge, characteristics of evolution and derivation of snow and ice risk events are analyzed on the basis of research on mechanism of evolution of snow and ice risk event. Taking the snow and ice disasters of 2008 in China as an example, the evolution of snow and ice risk events is divided into three types and the network structure of evolution of snow and ice risk event is worked out. Then the characteristics of derivation chain of snow and ice risk events are summarized and the characteristics of evolution of snow and ice risk events are analyzed, aiming at providing the theoretical basis for controlling evolution of snow and ice risk events.
