摘　　要：摸清西安市碳排放底数并了解其演变规律,是实现双碳目标的基础。基于《IPCC 2006年国家温室气体清单指南2019修订版》和《省级温室气体清单编制指南》,对西安市碳排放规律进行了动态分析和排放等级评估。研究结果表明,在1995—2020年,西安市碳排放增长迅速,从899.12万t上升至4912.14万t,年均增长7.03%;其中能源消耗部门占比最大(77.38%~89.46%),汽车排放领域增长最快,年均增长20.07%。人均排放、单位面积排放和碳排放指数增长较快,年均增量率分别为5.28%、6.98%和6.22%,排放等级由很低(Ⅰ_(b))升高至中下(Ⅱ_(a))等级;单位GDP排放呈下降趋势,年均降低率为6.63%。从创新绿色低碳技术、优化产业结构、激发碳排放权交易市场活力等方面提出对策建议。To find out the carbon emission base in Xi’an and understand its evolution law is the basis for realizing the dual carbon goal.Based on"IPCC 2006 National Greenhouse Gas Inventory Guidelines 2019 Revised Edition"and"Provincial Greenhouse Gas Inventory Compilation Guidelines",the dynamic analysis and emission level assessment of carbon emission laws in Xi’an were carried out.The results showed that during the period from 1995 to 2020,carbon emissions in Xi’an increased rapidly,from 8.9912 million tons to 49.1214 million tons,with an average annual increase of 7.03%.The energy consumption sector accounted for the largest proportion(77.38%~89.46%),and the automotive emission sector grew the fastest,with an average annual growth rate of 20.07%.The comprehensive index of per capita emission,emission per unit area and carbon emission increased rapidly,with an average annual increment rate of 5.28%,6.98% and 6.22%respectively,and the emission level increased from very low(Ⅰ_(b))to middle and lower(Ⅱ_(a))level.Unit GDP emissions show a downward trend,with an average annual reduction rate of 6.63%.Suggestions are put forward from the aspects of innovating green and low-carbon technologies,optimizing industrial structure,and stimulating the vitality of carbon emission trading market.
