摘要: 研究“三生空间”转型与碳收支演变机制,并科学设计碳补偿方案,对纠正“三生空间”资源错配和碳收支失衡具有重要意义。基于“三生空间”转型视角,在分析碳收支演变机制与碳补偿理论基础上,以西南地区为例开展实证分析,测算碳补偿金额、划分碳补偿优先级并做不确定性讨论。结果显示:(1)“三生空间”转型在重塑国土空间功能同时,推动碳收支时空演变。碳收支外部性是“三生空间”资源错配与碳收支失衡的重要原因,碳补偿是相应的纠正手段。(2)2005~2020年,西南地区“三生空间”快速转型,工业生产空间和城镇生活空间首先挤占农业生产空间、其次侵蚀草地和林地生态空间,加剧了区域碳收支失衡,碳平衡率从29.57%下降至17.94%。生产空间碳排放,以工业为主,增长迅速、增幅下降但尚未达峰。生活空间碳排放先增后降,城乡生活碳排放比例扩大。生态空间碳汇丰富,以林地为主,先增后降,总体有较小增幅。碳源空间规模是碳排放空间分异的关键因素。(3)西南地区对全国碳收支平衡的贡献显著,整体为碳补偿受偿区,建议受偿金额为259.97亿元,城市尺度上有甘孜、阿坝38个等碳补偿受偿区,内江、黔西南等9个碳补偿支付区。

Abstract: It is of great significance to study the transformation of production-living-ecological space and the evolution mechanism of carbon balance and design a carbon compensation scheme scientifically to rectify the mismatch of production-living-ecological space and the imbalance of carbon budget. Based on the perspective of the transformation of production-living-ecological space, this paper analyzed the evolution mechanism of the carbon budget and the theory of carbon compensation. An empirical analysis was conducted on the example of the Southwest China. The amount of carbon compensation was measured, and the carbon compensation and the uncertainty were discussed. The results showed that: (1) The transformation of production-living-ecological space contributed to the spatial-temporal evolution of the carbon budget while reshaping the spatial functions. The transformation also aggravated the mismatch of space resources and the carbon budget imbalance due to externality. Carbon compensation was an important mechanism for correcting the carbon budget imbalance. (2) From 2005 to 2020, there was a rapid transformation of production-living-ecological space in Southwest China. The industrial production space and urban living space crowded out the agricultural production space, grassland ecological space, and forest ecological space to realize rapid growth. All these transformations exacerbated the imbalance of the regional carbon balance, and the carbon balance rate dropped from 29.57% to 17.94%. Carbon emissions from production space were dominated by industrial carbon emissions, which was overgrowing and declining, and had not yet reached the peak. Residential carbon emissions increase and then decreased, with an increase in the proportion of urban and rural carbon emissions. Ecological space carbon sinks were dominated by forest carbon sinks, which increased and then decreased. The spatial scale of carbon sources was a key factor in the spatial differentiation of carbon emissions. (3) Southwest China played a substantial role in maintaining the national carbon balance,with a proposed amount of 25.997 billion yuan of carbon compensation to be received. At the city level, there were 38 compensation areas, including Ganzi and Aba, and 9 payment areas of Neijiang and Qianxinan.
