摘　　要：【目的】国土空间规划是实现“双碳”目标的重要抓手。明确区县单元的碳源碳汇核算和碳评价方法,有助于区县级国土空间规划摸清“碳底数”,从而为区县“减排增汇”策略的制定提供支撑。【方法】利用碳排放(吸收)系数法和层次分析法,构建区县域碳源、碳汇核算与碳评价模型,并以天津市武清区为例进行规划应用的实证研究。【结果】武清区全域碳平衡存在显著失衡,中心城区在碳源消纳方面起消极作用,武清区东部、中西部、中北部街镇在全区碳源消纳中起积极作用。武清区街镇的碳评价结果可分为5级,全区低碳状态自中心城区向外呈“差—优—差”的圈层分布,越靠近武清中心城区和北京通州区的街镇,低碳表现越差。【结论】武清区中心城区的人口集聚程度高、建设用地占比高,且发挥碳汇作用的沟渠、坑塘、林地等用地少,导致碳源集中。武清区东部、中西部、中北部街镇的生态相关用地碳汇作用明显。从碳评价结果看,需同时重视碳“减排”和碳“增汇”,才能改善街镇的低碳状态。武清区国土空间规划应依据各街镇的碳评价级别,结合各街镇的不同发展特征,分别制定低碳规划目标,分解传导规划指标,优化空间总体格局,引导产业低碳转型,推动全区高质量发展。[Objective]As an important tool for optimizing the territorial spatial pattern,territorial spatial planning has become a policy lever for promoting the achievement of the carbon peaking and carbon neutrality goals.However,from the current practice of territorial spatial planning in various regions,there is still a lack of consensus on how to implement the carbon peaking and carbon neutrality goals in planning.From the perspective of planning process,“dual evaluation”as a prerequisite research for territorial spatial planning is crucial for clarifying the background conditions of territorial spatial planning.However,existing guidelines and practices for“dual evaluation”often do not involve relevant content.From the results of territorial spatial planning at all levels,there are relatively few implementation plans directly incorporated into territorial spatial planning.From the perspective of planning hierarchy,the district and county levels are the key levels for implementing upper-level planning and ensuring smooth planning transmission.However,there has been relatively few research on planning response to the carbon peaking and carbon neutrality goals in territorial spatial planning at the district/county level.In summary,this research aims to clarify the methods for carbon source and sink accounting as well as carbon evaluation for district and county units,with Wuqing District,Tianjin as an empirical example.The major purpose is to help territorial spatial planning at the district/county level figure out“carbon”-related inventory and provide support for the formulation of“emission reduction and sink increase”strategies.[Methods]Firstly,based on the classification of land use types in the third national land resource survey,the calculation inventory of carbon source and carbon sink in Wuqing District,Tianjin is clarified.The carbon emission/absorption coefficient method is used to calculate the total carbon source and carbon sink of various district/county units in Wuqing District based on the a
