| 中文摘要 |
| 陆地生态系统的生产力对于区域生态安全和全球碳循环至关重要. 通过探究碳汇的时空变化及其生态价值，为政府减缓碳排放、实现碳中和的政策措施制定提供思路. 基于燕山-太行山2000~2021年净初级生产力计算碳吸收，夜间灯光数据拟合计算碳排放，分析碳中和的时空特征，运用二氧化碳扩散系数，计算固碳空间服务范围，结合经济生态综合指数（C-GDP），探究经济与生态发展之间的平衡. 结果表明：①2000~2021年燕山-太行山净生态系统生产力（NEP）在时间上波动上升，空间上呈现中间高值四周低值分布；燕山地区NEP高于太行山地区. ②固碳量在2018年之后呈上升趋势，燕山的固碳增长量高于太行山. ③2000~2021年燕山-太行山固碳服务范围为184.8~913.5 km，时间上为先减少后增加的变化趋势. ④C-GDP时间上呈现增长趋势，高碳汇的燕山C-GDP低于低碳汇的太行山，碳货币化的固碳价值低于高GDP区生产所带来的经济效益. |

| The productivity of terrestrial ecosystems is crucial for regional ecological security and global carbon cycling. Exploring the spatiotemporal changes of carbon sinks and their ecological value provides insights for the government to formulate measures to reduce carbon emissions and achieve carbon neutrality. Based on the calculation of net primary productivity （NPP） for the Yanshan-Taihang Mountains from 2000 to 2021 to estimate carbon absorption and fitting night-time light data to calculate carbon emissions， along with the use of carbon dioxide diffusion coefficients， the spatiotemporal characteristics of carbon neutrality and the spatial range of carbon sequestration services were analyzed. This was combined with the comprehensive economic and ecological index （C-GDP） to explore the balance between economic and ecological development. The results indicate： ① The net ecosystem productivity （NEP） of the Yanshan-Taihang Mountains fluctuated and Increased over time and spatially presented high values in the middle surrounded by low values， with a higher NEP in the Yan Mountains Region than in the Taihang Mountains Region. ② The carbon sequestration showed an increasing trend after 2018， with higher carbon sequestration growth in the Yanshan Mountains than in the Taihang Mountains. ③ The carbon sequestration service scope of the Yanshan-Taihang Mountains from 2000 to 2021 ranged from 184.8 to 913.5 km and showed a trend of decrease followed by an increase over time. ④ The C-GDP showed a growing trend over time， with the high carbon sink area of the Yanshan Mountains having a lower C-GDP than the low carbon sink area of the Taihang Mountains and the monetized value of carbon sequestration being lower than the economic benefits brought by high GDP production. |
