Abstract

Exploring the spatiotemporal differentiation of the carbon budget and clarifying the zoning of carbon compensation based on the perspective of the main function-oriented zones is of great significance for promoting regional low-carbon development and achieving the "dual carbon" goal. This study was conducted using 550 counties in the Yellow River Basin as the basic unit, and based on the concentration index to examine the spatial distribution characteristics of carbon emissions and carbon absorptions in the main function-oriented zones of the Yellow River Basin, a four-dimensional benchmark framework for carbon compensation zoning was constructed by total scale, economic contribution, ecological carrying capacity, and land development intensity. The SOM-K-means algorithm was used to establish a differentiated carbon compensation zoning scheme. The results showed that: ① The carbon emissions and carbon absorptions and their growth trends of the main function-oriented zones in the Yellow River Basin were in line with the positioning of the main functional area, and the significant space-time distribution characteristics of the concentration level of carbon emissions and carbon absorptions were shown. ② Significant regional differences exist in the four attributes of total carbon emissions scale, economic contribution, ecological carrying capacity, and land development intensity. The overall scale of carbon emissions showed a growth trend, with obvious comparative advantages in the midstream and downstream. The overall comparative advantage of economic contribution increased first and then decreased, with the midstream and downstream being the attribute advantage areas of economic contribution. The overall ecological carrying capacity had been improved, and the upstream had obvious advantages in ecological carrying properties. The advantageous areas for land development were mainly concentrated in the midstream and downstream; in particular, the comparative advantage index in the midstream was showing a rapid upward trend. ③ Moreover, there were 287 compensated areas, 78 balanced areas, and 185 payment areas in the Yellow River Basin. Eleven types of carbon compensation zones were finally formed by combining the comparative advantage index of four types of attributes with the plan for main function-oriented zones, and corresponding low-carbon development strategies were proposed for each type of zone.

[基于主体功能区规划的碳预算时空分异与碳补偿区划:黄河流域县域案例研究]。
基于主体功能区视角,探讨碳预算时空分异,明确碳补偿分区,对促进区域低碳发展、实现 "双碳 "目标具有重要意义。本研究以黄河流域550个县为基本单元,基于集中度指数考察黄河流域主体功能导向区碳排放和碳吸收的空间分布特征,构建了总规模、经济贡献、生态承载力和土地开发强度四维碳补偿区划基准框架。利用 SOM-K-means 算法建立了差异化的碳补偿区划方案。结果表明:①黄河流域主体功能导向区的碳排放和碳吸收量及其增长趋势符合主体功能区定位,碳排放和碳吸收量浓度水平呈现显著的时空分布特征。黄河流域碳排放总量规模、经济贡献率、生态承载力和土地开发强度四项属性存在显著的区域差异。碳排放总规模呈增长趋势,中下游比较优势明显。经济贡献的总体比较优势先增后减,中下游是经济贡献的属性优势区。生态承载能力整体提升,上游生态承载属性优势明显。土地开发优势区主要集中在中下游,特别是中游的比较优势指数呈快速上升趋势。此外,黄河流域共有 287 个补偿区、78 个平衡区和 185 个支付区。结合四类属性的比较优势指数和主体功能区规划,最终形成了 11 类碳补偿区,并为每类补偿区提出了相应的低碳发展战略。
