Abstract:

This article overviewed current research situation of emergencies and typical cases of China at the present stage,studied the process of incidents evolution,proposed that the whole process of emergency intervention and social factors as an important aspect of water pollution evolution.On this basis,this article analyzed the major dynamic factors of evolution of water pollution incidents,construction of the dynamic factors system of incidents evolution by applying disaster theory,emergency management and environmental science.Finally,this article built the evolution model of water pollution emergency incidents from the view of system analysis.The results show that social factors and emergency interventions promote the evolution of water pollution incidents;the evolution of water pollution emergency incidents exists phased;dynamic factors at different stages are different;water pollution incidents emergency management with multitargeted,single target emergency management cannot effectively control the evolution of water pollution incidents. Studying the evolution mechanism of water pollution emergency incidents,we can provide important theoretical basis for the government to take effective early warning measures and emergency decision at early stage
