在“双碳”背景下，城市道路照明系统低碳改造逐步由单一能耗控制转向精细化工程决策。现有研究多聚焦运行阶段节能优化，对不同道路在功率密度、布灯结构及运行管理方式等方面的差异性关注不足，统一改造路径难以满足多样化工程条件。本文基于南京市六条典型道路的运行参数与结构特征，构建道路照明低碳改造分型方法，将道路划分为高功率密度型、高单灯负荷型、运行冗余型及结构合理型，并分析各类型道路的技术适配路径与实施优先级。结果表明，结构优化适用于功率密度偏高路段，光源替换适用于单灯负荷较大的道路，智能控制在运行冗余型道路中具有较强适配性。差异化分型框架有助于提升改造针对性与资源配置效率，为城市道路照明系统精细化低碳更新提供决策依据。研究成果可为道路照明低碳改造路径选择提供方法依据，并为道路照明系统层面的减碳策略制定与优化提供实证支撑。

Under the "dual-carbon" policy framework,the low-carbon retrofit of urban road lighting systems is evolving from single-objective energy consumption control toward refined engincering decision-making.Existing studies primarily focus on operational energy-saving measures,while insufficient attention has been paid to the heterogeneity among roads in terms of power density,lighting layout configuration,and operational management patterns.As a result,uniform retrofit strategies may fail to accommodate diverse engineering conditions.Based on the operational parameters and structural characteristics of six representative urban roads in Nanjing,this study develops a classification approach for low-carbon retrofit pathways.Roads are categorized into high power-density,high single-lamp load,operational redundancy,and structurally optimized types.The technical suitability and implementation priority of retrofit strategies are analyzed for each category.The findings indicate that structural optimization is more suitable for roads with excessive power density,light source replacement is appropriate for roads with high single-lamp load,and intelligent control strategies demonstrate strong applicability in operational redundancy scenarios.The proposed differentiated classification framework enhances retrofit precision and resource allocation efficiency,providing a decision-making basis for the refined low-carbon upgrading of urban road lighting systems.
