【摘要】 [目的]合理划定城市增长边界（UGB）能有效控制城市不断扩张带来的大量碳排放，针对现有研究多基于单一目标且忽视碳达峰约束、难以协同多目标的问题，构建融入碳达峰目标的生态—经济多目标综合型UGB划定框架，为低碳城市建设提供新路径。[方法]以武汉市为例，通过耦合STIRPAT-InVEST-GMOP-PLUS模型，模拟碳达峰目标约束下武汉市不同生态—经济发展情景的未来城市用地格局，划定能协同“生态—经济”与碳达峰目标的UGB。[结果]（1） 9种碳达峰路径中只有促碳因素为低模式时才能完成武汉市2030年碳达峰的目标，其中达峰最小值为低低路径下的1 816.41万t。（2） 4种情景中，碳达峰目标约束下的3种情景城市扩张均得到了有效控制，但只有可持续发展情景经济效益和生态效益均较高，实现了生态—经济效益协同增长的目标。（3）选择低低达峰路径下具有碳储约束的可持续发展情景为武汉市最佳发展情景，并以此划定城市增长边界。[结论]低低达峰路径能够支撑武汉市于2030年实现碳达峰目标，武汉市最佳发展方案为碳储约束下的可持续发展情景，据此划定的2030年城市增长边界面积为1 214.93 km~2，且能同步实现生态—经济效益协同优化目标。更多还原

【Abstract】 [Objective] Rational delineation of Urban Growth Boundaries(UGB) can effectively mitigate substantial carbon emissions resulting from continuous urban expansion. Addressing the limitations of existing studies that predominantly focus on single objectives while neglecting carbon peak constraints and multi-objective coordination, this research proposes an ecological-economic multi-objective comprehensive UGB delineation framework integrated with carbon peak goals. This approach offers a novel pathway for advancing low-carbon city development. [Methods] Taking Wuhan City as an example, the future urban land use patterns under different ecological-economic development scenarios with peak carbon constraints were simulated by coupling the STIRPAT-InVEST-GMOP-PLUS model. It facilitated the delineation of UGBs that harmonize the ecologicaleconomic and peak carbon objectives. [Results](1) Among the nine peak carbon pathways, only the low-carbon promotion mode enabled Wuhan City to achieve the goal of peak carbon by 2030, with the minimum peak value recorded at 18.1641 million tons under the low-low pathway.(2) Among the four scenarios, urban expansion in three scenarios constrained by peak carbon goals was effectively controlled. However, only the sustainable development scenario achieved both higher economic and ecological benefits, realizing the goal of coordinated ecological-economic growth.(3) The sustainable development scenario with carbon storage constraints under the low-low pathway was selected as the optimal development scenario for Wuhan City, upon which the UGB was delineated. [Conclusion] The low-carbon peak pathway can support Wuhan City in achieving its carbon peak goal by 2030. The optimal development plan for Wuhan City is the sustainable development scenario under carbon storage constraints. Based on this plan, the delineated urban growth boundary area for 2030 is 1 214.93 km~2, while simultaneously achieving coordinated optimization of ecological and economic benefits.更多还原
