Abstract:The emergency planning system in China is an emergency plan network
   which consists of the different levels and different types of plans. To
   improve the emergency planning system and seek its best evolution mode,
   this paper, according to the establishment of emergency plans, extracts
   the ordered mode based on the administrative ranking and the disordered
   mode based on local demand that drive the establishment of the emergency
   plan are extracted. Considering the reference relationship between
   emergency plans, the ordered and disordered evolving network models of
   emergency planning system are proposed based on complex network. The
   simulation results indicate that the hierarchical structure of the
   emergency planning system exhibits scale-free property. Compared to the
   ordered evolving model, the emergency plans in the disordered evolving
   model which according to the actual needs have smaller individual
   differences, and the operation of the emergency planning system is
   affected by most emergency plans, not only depend on the high-level
   emergency plans. The disordered evolving model makes the emergency
   planning system more stability and more long-term effectively.
