The invention provides an emergency command cloud service implementation method and system based on a microkernel cluster. Various kinds of services with specific business processing capacity is virtually encapsulated into the microkernel cluster, mutual synergy is performed according to the service plans generated according to upper module application, and the microcosmic services provided each member in the cluster are combined and encapsulated to convert into macroscopic service manners capable of realizing emergency treatment task planning. The system comprises a physical resource layer, an emergency resource cloud pool, a platform service layer, a module application layer and a user layer. By the emergency command system built by the service method, dynamic searching of valuable emergency service resources in various fields can be achieved, the system capabilities of massive dynamic information and knowledge reasoning, complex function and process recombination calculation, storage and service are improved, and diversified emergency tasks such as emergency cross-department and cross-field real-time information processing, large-range public opinion analysis, complex module deduction, dynamic disaster situation prediction and remote monitoring can be achieved.
