摘 要:以空间网络结构理论为基础,将公共危机信息传播系统界定为由信宿、信源为节点,传播途径为连接线的占据一定空间范围的拓扑网络。并用节点数、结构指数、平均径路长等参数对公共危机信息传播网络结构进行了空间分析,最后探讨了公共危机信息传播网络结构模式的实用意义和指导价值。The spatial network model of public crisis information communication system is discerned and analyzed in this paper. The spatial model of public crisis information communication system is a network composed of two types of nodes, destination and origins connected by communication route links centered with destination place. The paper analyzes the topological properties of the public crisis information communication network using several indexes such as α,β,γindexes and the shortest path matrix. The values of those indexes and the shortest path matrix of the network in figure 1 are calculated separated. Those indexes give a way to estimate the network quantitatively. The applications of the spatial network model in several areas and at many levels of analysis are discussed in details. In academic research it call serve as a reference point for general an d specific studies.In summary,the spatial network model provides governments a valuable approach to public crisis information communication policy and manager.
