建成区对全球温室气体排放的贡献显著，而空间规划则是建成区碳排放控制中不可或缺的战略性手段。鉴于建成区内土地利用模式和碳排放源的多样化，本研究提出了一项基于建设用地的碳排放评估与优化策略体系，并将其整合为规划友好型工具，包含“基于用地现状的碳排放强度计算”、“基于用地规划的碳排放强度空间分析”、以及“规划方案优化与减排效果评估”三个实施步骤。该工具应用于浙江省长兴县中心城区的用地规划方案优化中，结果表明，土地利用的结构和碳排放强度显著影响了长兴县中心城区的总碳排放量。通过优化土地利用的结构和强度，中心城区的总碳排放量相较于原规划方案减少了36.9%。此外，蒙特卡罗模拟的结果表明，建设用地的结构优化和碳排放强度控制分别可减少5.20%—18.28%和18.44%—31.67%的总碳排放量。以上结果强调了调整用地结构和实施用地碳强度控制在减少建成区碳排放中的重要作用。总体而言，本研究为城市管理与规划者在创建可持续、低碳城市方面提供了方法与见解。

Built-up area (BUA) significantly contributes to global greenhouse gas emissions, making strategic spatial planning crucial for carbon emission control. Given the diverse land use patterns and carbon emission sources in BUAs, this study proposed a land-based strategy system for carbon emission assessment and optimization. A three-step method was devised to create a planner-friendly tool for implementing the system, which involves carbon emission intensity calculation based on current land use, spatial illustration of carbon emission intensities based on land use planning, and planning program optimization and emission reduction effect assessment. The method was applied to the central urban area of Changxing County (Zhejiang) in China. The results showed that the structures and emission intensities of urban land use substantially influenced the overall carbon emissions in the central urban area. Our comprehensive land use optimization strategies reduced the overall carbon emissions of the central urban area by 36.9% when compared to the original planning program. The Monte Carlo simulation indicated that land use structure optimization and emission intensity control measures could reduce carbon emission rate by 5.20% to 18.28%, and 18.44% to 31.67%, respectively. The results underlined the importance of making specific adjustments to land use structure and implementing intensity control measures for effective carbon reduction. In conclusion, this study offers methods and insights for urban planners in creating sustainable and low-carbon urban spaces.
