摘    要:区域大气环境风险源的有效识别与危险性评估对区域大气环境风险评价和区域大气环境污染防控具有重要意义.为构建区域大气环境风险源识别与危险性快速评估的方法,本研究将系统安全工程学中的经典半定量方法可能性-暴露-后果评估法(LEC法)与管理咨询工程中的经典定量方法德尔菲(Delphi)法相结合,应用于区域大气环境风险源识别与危险性评估,给出了大气环境事故发生的可能性L、风险源暴露于大气环境的频繁程度E、发生大气环境事故后风险源的不可控程度C和风险源的危险程度D的量化评估的分值标准.将该方法应用于我国北方某大型煤炭港口的案例评估,评估结果表明,大规模煤炭露天储存场所中存在的风险源和堆料机、装船机、取料机作业过程中产生的风险源是该港口区域的主要大气环境风险源.评估结果有效性检验表明,区域大气环境风险源的特征和危害程度与实际情况较为符合.风险源的快速有效识别与评估可为区域大气环境风险评价和区域大气环境污染防控提供重要的参考.

关 键 词:风险源  环境风险  大气环境  区域环境  LEC法  德尔菲法

Abstract:Identification and assessment for atmospheric environment risk source plays an important role in regional atmospheric risk assessment and regional atmospheric pollution prevention and control. The likelihood exposure and consequence assessment method (LEC method) and the Delphi method were employed to build a fast and effective method for identification and assessment of regional atmospheric environment risk sources. This method was applied to the case study of a large coal transportation port in North China. The assessment results showed that the risk characteristics and the harm degree of regional atmospheric environment risk source were in line with the actual situation. Fast and effective identification and assessment of risk source has laid an important foundation for the regional atmospheric environmental risk assessment and regional atmospheric pollution prevention and control.
Keywords:risk sources  environment risk  atmospheric environment  regional environment  LEC assessment method  Delphi analysis
