近地小行星撞击事件处置规则与处置流程OA北大核心CSTPCD

In response to the shortcomings in the areas of disposal rules,coordination mechanisms,and operational procedures in China's research on the defense of near-Earth asteroids,a simulation strategy for asteroid defense is proposed to meet the increasing demand for asteroid defense and disaster relief.Based on the current development status of asteroid defense at home and abroad,the gaps in China's as-teroid defense are analyzed.From the perspectives of mechanism establishment and coordinated emer-gency response,the simulation and deduction of asteroid defense at home and abroad are analyzed.Based on the current research status at home and abroad,a set of asteroid defense simulation and de-duction plans are designed,and an organizational structure for China's asteroid defense exercises is pro-posed,including three levels:guidance layer,event disposal layer,and business support layer,providing basic organizational support for asteroid defense exercises.The emergency response mechanism and gen-eral disposal rules for asteroid impact events are proposed,providing a rule basis for the disposal of events and the operation of each level in the organizational structure.The simulation scenarios are ini-tially designed to verify the mechanisms and rules,providing a reference for the organization and imple-mentation of near-Earth asteroid defense work.
