| 土地利用功能演变深刻影响着生态系统服务变化. 为探究土地利用功能对生态系统服务价值（ESV）的影响，以黄河流域沿线2000~2022年69个地级市为研究区，利用土地利用功能转移矩阵、权衡-协同关系和敏感性分析等方法，研究土地利用功能时空演变特征和ESV损益与响应. 结果表明：①22 a间黄河流域沿线土地利用类型呈现建设用地显著扩张、农田和草原面积减少态势；土地利用功能演变最突出特征是生产生态功能缩减与生活生产功能用地大幅提升，前者转移面积最大，且转移速度远高于其同期新增速度，至2022年净减少29 708.18 km2，后者新增速度大于转移速度，净增加19 770.83 km2. ②研究期内黄河流域沿线ESV增加1 249.56亿元，其中表征生态功能的森林和表征生态生产功能的水域对ESV贡献最大；水文调节、气候调节和土壤保持是黄河流域最主要的生态服务功能类型，不同服务类型以协同关系为主. ③黄河流域沿线ESV对不同土地利用功能演变的响应程度具有显著异质性，生态功能转型为生态生产功能对ESV增加的贡献率最大，达101.78%；生产生态功能演变为生活生产功能对ESV降低的贡献度最高，达37.81%. 研究结果对于黄河流域沿线土地资源可持续利用和生态安全格局优化具有一定的决策参考价值. |

| The evolution of land use functions profoundly influences the changes in ecosystem services. To explore the impact of land use functions on ecosystem service value （ESV）， this study took 69 prefecture-level cities along the Yellow River Basin from 2000 to 2022 as the research area. Employing methods such as the land use function transition matrix， trade-off and synergy relationships， and sensitivity analysis， the spatiotemporal evolution of land use functions and the gain-loss and response of ESV were examined. The results show that： ① Over the past 22 years， the land use types along the Yellow River Basin have shown a significant expansion of construction land and a reduction in the area of farmland and grassland. The most prominent feature of the evolution of land use functions was the reduction of production-ecological functions and the significant increase in land for living-production functions. The former had the largest transfer area， and its transfer speed was much higher than its new addition speed. By 2022， it had a net reduction of 29 708.18 km2. The latter had a new addition speed greater than the transfer speed， with a net increase of 19 770.83 km2. ② During the study period， the ESV along the Yellow River Basin increased by 124 956 billion yuan. Among them， forests， which represent ecological functions， and waters， which represent ecological production functions， made the greatest contributions to ESV. Hydrological regulation， climate regulation， and soil conservation were the most important types of ecosystem services along the Yellow River Basin， and different type of ecosystem services were mainly in a synergistic relationship. ③ The response degree of ESV to the evolution of different land use functions along the Yellow River Basin had significant heterogeneity. The transformation of ecological functions into ecological production functions had the greatest contribution rate to the increase of ESV， reaching 101.78%. The transformation of production-ecological functions into living-production functions had the highest contribution to the decrease of ESV， reaching 37.81%. The research results have certain decision-making reference value for the sustainable utilization of land resources and the optimization of the ecological security pattern along the Yellow River Basin. |
