Identification and classification methods for mobile environmental risk sources
移动型环境风险源识别与分级方法研究

In this study, the method was developed to identify mobile environmental risk sources and to classify the environmental risks, aiming at efficiently managing the mobile environmental risk sources and reducing the risk level in their transport process. This method was based on our current statistical analysis of environmental pollution accident, using factor analysis which can reflect the causes and the characteristics of the accidents to quantify the level of the environmental risk sources. The influence factors, characteristics of the environmental risk sources intensity and risk characterization method were analyzed in the classification. Additionally, a risk classification matrix was setup based on the amount of material to the risk and the level of environmental risk. Thus, a two-step classification method was established by combining "environmental risk sources screening" and "risk classification" so as to directly manifest the risk level of environmental risk sources, and to enhance the operability and practicability of the method.
