摘　　要：介绍区域定量风险评价的基本原理和评价指标,建立风险计算模型,给出定量风险评价的程序,提出区域定量风险评价方法;利用开发的个人风险计算软件,对某化工园区中区域风险进行了评价;通过分析计算,给出了该区域的个人风险等值线分布图和社会风险图;结果表明,园区中3家企业的重大危险源需进一步采取措施降低风险,使该化工园区的个人风险和社会风险符合推荐标准的要求。该方法为全面了解化工园区风险提供了理论依据,对化工园区装置的布置和科学规划具有重要的指导意义。The basic principle and assessment criterion of Quantitative Area Risk Assessment （QARA） is introduced. A model for QARA is developed and procedure for the QARA is proposed. The developed individual risk calculation software is utilized to assess the risk of a certain chemical industrial park. The individual risk isoline and the social risk chart are obtained through analysis and calculation. The results show that major hazards of three factories in the park need to take further measures to reduce risk in order to make sure that the individual risk and the social risk of chemical industry park will meet the require- ments of recommended standards. The method provides a theoretical basis for the overall understanding of risk of the chemical industry park is of great significance for layout and scientific planning of devices in chemical industry park.
