Combining the special plans of information on railway and the investigations in Qingzang Company, The main task of this paper is to discuss the information sharing mechanism of Qingzang railway emergency rescue system, which is to provide guidance and supports for emergency and rescue scientifically and practically.Qingzang railway emergency rescue system needs to acquire the necessary basic information and business information from multiple business systems. These data may be stored and managed in a radically different way. Therefore, it is essential and critical that the decentralized and heterogeneous data should be organized well in order to make information shared between the emergency rescue system and other operational systems and external systems.Firstly the issues of information sharing were questioned, and then the organization and management of spatial data, spatial data sharing methods and other important technologies were researched concretely; secondly with the characteristics of Qingzang Railway emergency rescue system, the particular information sharing needs were raised; thirdly, on the basis of the existing theories and technologies, the information sharing model was discussed; lastly the realization of the information sharing mechanism that was applied in the Qingzang railway emergency rescue system were researched, including information classification and coding, storage and management of data and information sharing and exchange.
