基于碳中和目标的城市低碳发展水平评价研究:以安徽省为例
Evaluation of urban low-carbon development level based on the carbon neutrality goal: a case study of Anhui Province
【目的】在全球气候变化背景下,低碳城市建设对实现碳中和至关重要。针对当前评估工具不足的问题,构建科学评价体系以指导城市低碳转型。【方法】基于碳中和目标,构建涵盖“减碳—增汇”双维度、7个准则层及33项指标的评价体系,采用AHP(analytic hierarchy process)-熵权组合赋权TOPSIS(technique for order preference by similarity to ideal solution)模型,对安徽省16个地级市2013—2022年低碳发展水平进行测度,并结合障碍度模型识别关键制约因素。【结果】(1)2013—2022年安徽省城市低碳发展水平整体稳步提升,且城市间差异略有收敛。全省综合得分均值由0.373升至0.478,合肥与黄山长期位居前两位,芜湖稳定处于前列;宣城提升幅度最大,蚌埠和马鞍山亦呈现一定追赶态势。同期,低评价水平城市由淮南、马鞍山转变为淮南、铜陵,表明在整体抬升背景下,城市位序仍发生了明显重组。(2)安徽省城市减碳水平持续提升,逐步形成以合肥为极核、芜湖和黄山等为重要支点的多点高值格局;而增汇水平总体呈上升趋势,空间上保持显著的南高北低分异特征,黄山、池州、宣城等皖南城市优势突出。(3)障碍度模型分析表明,不同类型城市面临差异化的低碳发展阻碍,凸显低碳转型路径的多元挑战。【结论】各市应针对低碳转型的路径分化与类型化障碍实施差异化治理,立足“减碳—增汇”双向路径精准施策,以协同策略驱动全省低碳转型的系统提升与目标达成。
[Objective] In the context of global climate change, the development of low-carbon cities is crucial for achieving carbon neutrality. Addressing the current inadequacy of assessment tools, this study establishes a scientific evaluation system to guide urban low-carbon transformation. [Method] Based on the carbon neutrality goal, an evaluation framework encompassing the dual dimensions of "carbon emission reduction" and "carbon sink enhancement" was constructed, comprising 7 criterion layers and 33 indicators. Using an AHP (analytic hierarchy process)-entropy weight combined TOPSIS (technique for order preference by similarity to ideal solution) model, the low-carbon development levels of 16 prefecture-level cities in Anhui Province from 2013 to 2022 were assessed and key constraints were identified through obstacle degree modeling. [Result] (1) from 2013 to 2022, the overall low- carbon development level of cities in Anhui Province improved steadily, with the provincial mean comprehensive score increasing from 0.373 to 0.478, while inter-city disparities narrowed slightly. Hefei city and Huangshan city consistently ranked among the top two; Wuhu city remained in the leading group; and cities such as Xuancheng city, Bengbu city, and Ma’anshan city showed notable improvement. The lowest-ranked cities shifted from Huainan city and Ma’anshan city in 2013 to Huainan city and Tongling city in 2022, indicating significant rank restructuring during the overall upward transition. (2) The carbon reduction level continuously improved, gradually forming a multi-polar high-value pattern led by Hefei city and supported by Wuhu city and Huangshan city. The carbon sequestration level also increased overall and maintained a clear spatial pattern of high values in southern Anhui Province and low values in northern Anhui Province, with Huangshan city, Chizhou city, and Xuancheng city exhibiting clear advantages. (3) Obstacle analysis indicates distinct development barriers across city types, highlighting the multidimensional challenges in low-carbon transitions. [Conclusion] Cities should implement differentiated governance strategies tailored to pathway divergence and typified obstacles in their low-carbon transitions. Precise policy implementation should be based on the dual pathways of "carbon reduction and sink enhancement", driving systematic improvement and achievement of the province's low-carbon transition through synergistic strategies.
