【Abstract】 With respect to hazardous chemical accidents, this paper proposes an evacuation decision making system based on ArcGIS. Its framework, functions and database design are discussed in details. Through an example of liquid chlorine of twenty tons being leaked totally within a short time under the wind speed of 5.4 m/s, how to analyze the damage and find an effective evacuation method by using the system are demonstrated.更多还原
