Methods: This paper mainly adopts the descriptive, comparative and induction research methods. The current status of medical support in MOOTW in China, America, Russia, Israel, Canada, had been studied through some official papers, and series of professional books by analysis the precise date in various kinds of emergency event. Results: The contrast shows that there is still a quite huge development in medical support in MOOTW, no matter in China, or in other countries. Conclusion: In order to strengthen the forces, besides building professional rescue teams, it is necessary to take a regular revise of plans, according to missions` needs.展开更多

For the restricted emergency rescue resource in a single city, it has become more and more imminent for the demand of the intercity collaborative resistance to major accident, so as to improve the protection capacity of urban security. In order to find an effective intercity, emergency rescue collaborative system, this paper introduces the concept and analysis method of ecosystem theory into intercity emergency, rescue. Based on the analysis of the formation-process of emergency rescue individual, population and community： a throe-level intercity emergency rescue collaborative system is constructed according to the characteristics of dynamics and structure of intercity emergency rescue ecosystem then the collaboration mechanism of information, resource and process in the interceity emergency rescue ecosystem is also studied in this paper; so as to offer available strategy and method for the ecosystem theory applied to intercity, emergency rescue. Through the studies of intereity emergency rescue ecosystem. it illuminates that the proposed emergency system can not Only cope with the major accident more timely and effectively but also integrate the intercity information resources and emergency rescue resource and process optimization.展开更多
