摘要：At present, the emergency management has become a hot issue. From the
   knowledge need of emergency management, this paper researches the
   relationship characteristics of unexpected event object elements and
   proposes the knowledge navigation model based on event chain. This model
   has five parts: resources model, knowledge ontology model, emergency
   disposal model, event object model and event chain model. Through the
   studies on relationship between different models, we provide users with
   convenient, speedy and timely knowledge navigation. At last, an
   application example is given to present the realization process of the
   model.
