Abstract: Geological disaster emergency prevention and control should adopt scenario-response model; furthermore, the emergency planning and its decision making should be based on disaster scenarios analysis and deduction. The static characteristics of scene are manifested as cognition to geological disaster risk, which could be described by some key points such as the features of geological body, disaster bearing body and geological environment. Based on evolution consequence analysis, the dynamic characteristics of scenario are manifested as the results of the evolution, namely the response demand change of the key nodes. Through characteristics analysis of emergency response to the scenario parameters, a preliminary scenario classification framework is put forward, in which the emergency response time and hazard scope are primary criteria, the geological features and trigger factors are secondary criteria, and satisfactory degree of treatment ability are auxiliary criteria. We pointed out the key points of emergency response to several typical scenarios in geological disaster prevention, such as single-point landslide, single dangerous rock collapse, debris flow, inter-region geological disasters, regional heavy rainfall, earthquake-induced secondary geological disasters and so on.
