With global warming,the continuous increasing of urban heat island effect and the inherent vulnerability of urbanization make most regions face the potential threat of high temperature heat waves. Therefore,the compilation and research of contingency plan for high temperature heat waves has become the essential route of the improvement of risk management and emergency response capability. Nevertheless,there is neither systematic plan nor related research for high temperature heat wave nowadays. In addition,The construction of collaborative linkage among different agency was often neglected in the sporadic research of contingency plan for meteorological disasters. In response to above-mentioned,on the basis of the establishment of the plan system for high temperature heat waves,this paper introduces the collaborative linkage mechanism into the emergency management for high temperature heat waves,discusses the organization structure and operation process of the emergency settlement,then to highlight the task disassembling in the different contingency procedure and the collaborative linkage among different agency in each project. Eventually,according to the the big data platform,this paper proposed to establish a multiscene adaptive system of contingency plan,then to supervise and feedback the implementation effect,achieve the optimizing control in all process,thus to ensure the operability of the contingency plan and enhance the effectiveness of contingency management.
