摘　　要：【目的】在“双碳”战略与绿色数字生态文明建设背景下,针对国土空间规划中街区级碳排放空间评估方法缺失、管控单元传导机制不健全等问题,探索将碳排放空间评估和低碳规划融入国土空间规划体系的应用方法与实施路径。【方法】以广州市为例,基于局地气候分区(local climate zone,LCZ)框架,运用自下而上结合自上而下的空间分配方法,开展覆盖工业、交通、居住及公共服务、商业、农业五部门的精细化碳排放空间评估,绘制碳排放分级管控单元地图,识别碳排放热点单元。【结果】碳排放热点主要聚集于LCZ分类中的高密度类型区,如LCZ 1(高层高密度区)、LCZ 2(多层高密度区)和LCZ 3(低层高密度区),不同碳排放分级管控单元的LCZ类型存在显著差异。针对不同部门的碳排放一级管控单元街区提出差异化规划策略:工业街区推进产业集约化与清洁技术集成;交通街区发展公交导向与能源网络重构,构建绿色出行系统;居住及公共服务街区依托建筑能效提升与可再生能源替代,实施节能更新;商业街区鼓励建筑的混合用途开发与微气候调节;农业街区建议发展循环农业与生态碳汇保育。【结论】提出低碳规划融入国土空间规划五级三类体系层级、编制—审批—修改—实施—监督全流程,以及现状研究—数据建库—规划编制—平台管理的技术路线,为国土空间规划的城市绿色发展转型提供方法参考。[Objective]Cities are the primary spatial carriers of human production and living activities,as well as concentrated areas of carbon emissions.Therefore,building low-carbon cities is crucial for advancing the carbon peaking and carbon neutrality goals.Given the spatial heterogeneity of urban morphology and carbon emissions,this research aims to develop fine-scale spatial assessment tools for carbon emissions.The research analyzes the impact of urban morphology on carbon emissions and investigates the integration of emission models with low-carbon planning strategies within the territorial spatial planning framework.The ultimate goal is to provide informational support and a decision-making foundation for low-carbon territorial spatial planning and digital green governance.By understanding the spatial distribution and sources of carbon emissions,urban planners can devise more effective interventions to mitigate urban carbon emissions.The research also addresses the gap between theoretical models and practical applications in urban planning and policymaking,and offers a framework adaptable to diverse urban contexts.[Methods]Based on the local climate zone(LCZ)framework,the research develops LCZ classification maps and a series of urban morphology analysis maps for Guangzhou.Furthermore,a refined spatial carbon emission assessment map is constructed using a combination of top-down and bottom-up approaches,which involves the following steps.First,by integrating planning data from the ArcGIS geographic information platform,such as data on buildings,streets,terrain,and land use,along with remote sensing and meteorological data,key urban morphology parameters,including building coverage ratio,building volume density,sky view factor,and street aspect ratio,are calculated at a grid scale of 300 m*300 m.These parameters are then used to develop LCZ classification and urban morphology maps,providing a data foundation for spatial carbon emission modelling.Subsequently,by calculating proxy indicators such as building volume d
