The invention provides a scene sequence construction method and apparatus. The method comprises the steps of obtaining scene elements of a current scene; determining scene rules matched with the scene elements according to the scene elements; deducing at least one group of scenes corresponding to the scene elements according to the scene rules; taking the at least one group of the scenes as the current scene, and repeatedly executing the steps until a predetermined quantity of scenes are obtained; and constructing a scene sequence according to the predetermined quantity of the scenes. A process of an emergency event and possibly caused subsequent scenes are described through the scene sequence; the visualization and instantiation of the scene sequence of the emergency event are realized; and a basis is provided for a decision-making subject of the emergency event to master and predict a dynamic change law of the scenes in real time, so that key decision-making points are searched for and confirmed, the emergency decision-making efficiency and the emergency response capability are improved, and a basic decision-making basis is provided for emergency preparations, emergency plans and real-time decision-making.
