| 生态系统服务关乎人类福祉，土地利用变化（LUCC）会影响碳排放和生态系统服务价值（ESV），研究两者之间的时空关系，对促进绿色可持续发展具有重要意义. 因此，在“双碳”目标和建设生态文明背景下，山西作为产煤大省，以此为研究区，基于2000~2020年土地利用以及社会经济数据，采用空间自相关分析方法探讨碳排放与ESV的时空演变特征以及交互作用规律. 结果表明：①2000~2020年，山西省主要地类为耕地、草地和林地，建设用地和林地面积呈增长趋势，其余各地类面积呈减小趋势. ②山西省土地利用净碳排放量逐年增长，由2000年净碳排放量3 465.06万t增长到2020年的12 480.09万t；土地利用碳排放强度高值区主要集中于中部地区，且不断向四周延伸，低值区主要分布于各城市边缘，且面积不断减少. ③山西省2000年生态系统服务价值为2 691.29亿元，2020年为2 646.88亿元，价值下降缓慢，林地和草地对ESV贡献率最多；ESV空间分布差异明显，年变化显著. ④2000~2020年，山西省土地利用碳排放强度与ESV强度存在明显负相关，土地利用碳排放强度越强，ESV强度就越弱，且通过了P值检验. 研究结果有助于为山西省土地利用规划相关工作和生态环境政策制定提供科学依据，从而推动产业的转型升级以及社会经济的可持续发展. |

| Ecosystem services are related to human well-being， and land use change （LUCC） can affect carbon emissions and ecosystem service value （ESV）. Studying the spatiotemporal relationship between the two is of great significance for promoting green and sustainable development. Therefore， in the context of the “dual carbon” goal and the construction of ecological civilization， Shanxi， as a coal-producing province， was taken as the research area， based on land use and socio-economic data from 2000 to 2020， using spatial autocorrelation analysis methods to explore the spatiotemporal evolution characteristics and interaction laws of carbon emissions and ESV. The results indicate that： ① From 2000 to 2020， the main land types in Shanxi Province were cultivated land， grassland， and forest land. The area of construction land and forest land showed an increasing trend， while the area of other land types showed a decreasing trend. ② The net carbon emissions from land use in Shanxi Province have been increasing year by year， from 34.65 million tons in 2000 to 124.80 million tons in 2020. The high value areas of land use carbon emissions intensity were mainly concentrated in the central region and continued to extend to the surrounding areas， while the low value areas were mainly distributed on the edges of various cities， and their area continued to decrease. ③ The ecosystem service value in Shanxi Province was 269.13 billion yuan in 2000 and 264.69 billion yuan in 2020， with a slow decline in value. Forest and grassland had the highest contribution rates to ESV. The spatial distribution of ESV varied significantly， with significant annual changes. ④From 2000 to 2020， there was a significant negative correlation between land use carbon emission intensity and ESV intensity in Shanxi Province. The stronger the land use carbon emission intensity， the weaker the ESV intensity， and it passed the p-value test. The research results contribute to providing scientific basis for land use planning and ecological environment policy formulation in Shanxi Province， thereby promoting industrial transformation and upgrading as well as sustainable socio-economic development. |
