城市燃气安全韧性量化评估体系构建与应用分析

Construction and application analysis of a quantitative evaluation system for urban gas safety resilience

燃气是一种高效、稳定、低碳的清洁能源,在“碳达峰、碳中和”目标背景下,大力推进城市燃气发展可有效提高能源利用效率,既是满足城市高品质用能需求的有效路径,又是推动节能降碳,实现城市绿色低碳转型的重要举措。由于燃气具有易燃、易爆、易扩散等特点,随着城市燃气的快速发展,燃气安全问题愈发突出,相关事故时有发生。为有效防范化解燃气安全风险与隐患,坚决遏制重特大事故发生,更好推动燃气行业高质量发展,本文坚持目标性、系统性、可行性、科学性、本土性五大导向,首次将韧性评估的方法论与燃气安全评估工作相结合,应用层次分析法建立了城市燃气安全韧性量化评估体系,对城市燃气安全相关指标进行全面梳理、摸排与评估,为推进城市燃气本质安全提供有力支撑。

Gas is an efficient,stable,and low-carbon clean energy.In the context of achieving carbon peak and carbon neutrality goals,vigorously promoting the development of urban gas can effectively improve energy utilization efficiency.It is not only an effective path to meet the high-quality energy demand of cities,but also an important measure to promote energy conservation and carbon reduction,and achieve green and low-carbon transformation in cities.Due to the characteristics of flammable,explosive,and easily diffusible nature of gas,with the rapid development of urban gas,gas safety issues have become increasingly prominent,and related accidents have occurred from time to time.In order to effectively prevent and resolve gas safety risks and hidden dangers,resolutely curb the occurrence of major accidents,and better promote the high-quality development of the gas industry,this article adhered to the five guiding principles of goal,systematicity,feasibility,scientificity,and localization.For the first time,the methodology of resilience assessment was combined with gas safety assessment.The Analytic Hierarchy Process was applied to establish a quantitative evaluation system for urban gas safety resilience,which sorted out,formulated,and evaluated indicators related to urban gas safety,providing strong support for promoting the intrinsic safety of urban gas.
