| Abstract: | In order to analyze the consequence influence of major toxic gas leakage accidents and the relevant evacuation region, a system on regional evacuation analysis of major toxic gas leakage accidents was constructed based on GIS. The business procedure and data procedure of regional evacuation analysis were analyzed, then the overall structure and data structure of the system were designed. The diffusion simulation was carried out combined with the specific case, and the accident influence region and the regional evacuation effect were analyzed. The results showed that the evacuation efficiency by using the way of hybrid notification was the highest, and the surrounding residents should be notified as soon as possible in response to the toxic gas leakage accident. |
