中文摘要:

以安徽省为研究区，基于2005—2020年土地利用净碳排放量数据，核算经济贡献系数及生态承载系数，分析空间碳平衡特征，应用土地利用隐性形态指标体系及地理探测器模型分析隐性因子对碳排放的驱动影响。结果表明：2005—2020年安徽省土地利用净碳排放量总体呈上升趋势，从2 404735 3×104t上升到4 634790 7×104t，增幅逐年降低，空间格局呈“东北高，西南低”的分布特点；根据净碳排放量、经济贡献系数、生态承载系数将安徽省各地级市归为碳汇功能区、低碳经济区、碳汇优化区、碳汇发展区、高碳控制区5类，其中低碳经济区和高碳控制区在缓慢扩张；影响净碳排放量的土地利用隐性因子在不同时期存在差异性，地均GDP和城市化率是关键驱动力，并主要集中于碳汇发展区和高碳控制区。

英文摘要:

Taking Anhui Province as the research area， based on the net carbon emissions data of land use from 2005 to 2020， this paper quantified the economic contribution coefficient and ecological carrying coefficient， analyzed the characteristics of spatial carbon balance， and applied a latent morphology indicator system and a geographic detector model to study the driving effects of latent factors on carbon emissions. The results indicated that from 2005 to 2020， the net carbon emissions from land use in Anhui showed an overall upward trend， rising from 2 404735 3 ×104 t to 4 634790 7×104 t， the rate of increase decelerated annually. The spatial pattern was characterized by a distribution of “high in northeast and low in southwest”. According to net carbon emissions， economic contribution coefficient and ecological carrying coefficient， the prefecture level cities in Anhui were classified into five categories including carbon sink functional zone， low carbon economic zone， carbon sink optimization zone， carbon sink development zone and high carbon control zone， among them， the low carbon economic zone and high carbon control zone were expanding slowly. The latent factors of land use affecting net carbon emissions varied across different periods. GDP per unit area and urbanization rate were key driving forces， and mainly concentrated in carbon sink development zone and high carbon control zone.
