摘　　要：针对氯气泄漏潜在的危害,对氯气泄漏扩散进行风险分析,选用高斯模型来计算氯气泄漏浓度及扩散距离,并通过Matlab对氯气泄漏进行数值模拟,能够掌握氯气泄漏后的浓度分布及泄漏扩散后浓度随距离的变化情况,确定人员疏散的安全警戒距离,掌握氯气泄漏扩散浓度分布与大气稳定度等因素的变化关系,确定人员中毒及伤害范围,可以为生产企业和其他相关部门应急反应决策提供技术支持.According to the potential harm of the chlorine,this paper analyzes the risk of the chlorine leakage dispersion,chooses the Gauss model to calculate the chlorine leakage dispersion concentration and distance,and uses Matlab to simulate the chlorine leakage dispersion pictures.According to the risk analysis,we can grasp the concentration distribution and changing with the distance after the chlorine leakage,determine the safety distance for evacuation,obtain the relationships about concentration distribution with the atmospheric stability and other factors,we can also determine the scope of poisoning and injury.It can provide technical support for the enterprises and relevant departments to emergency response decision-making.
