摘　　要：城镇化作为人类社会发展的重要特征,深刻改变了生态系统的功能、结构和过程,加剧了自然生态系统向半自然生态系统和人工生态系统的转变。本研究以黄河流域中上游地区为研究对象,分析该地区城镇化水平和生态系统服务价值的时空演变特征,并运用地理加权回归模型探讨城镇化子系统对生态系统服务价值的影响机制及动态变化。研究结果表明:(1)该地区城镇化水平显著提升,其城镇化发展模式也正在经历重大转型,形成了以中心城市为核心的“多中心、组团式”的城镇化空间格局。(2)该地区生态系统服务价值呈现出稳步增长态势,呈现西北部高原地区高、东南部平原地区低的总体空间格局。(3)该地区城镇化对生态系统服务价值的影响呈现出显著的空间异质性。其中,土地城镇化对生态系统服务价值产生了显著的负向影响;经济城镇化的影响则从负向影响逐渐转变为正向影响;人口城镇化和社会城镇化则同时存在正向影响和负向影响。研究丰富了对流域尺度自然系统与人类系统相互关系的理论认识,也为合理制定区域发展规划和生态保护政策提供了科学依据,具有重要理论意义和实践价值。Urbanization,as a significant characteristic of human societal development,profoundly alters the functions,structures,and processes of ecosystems,accelerating the transformation from natural ecosystems to semi-natural and artificial ones.This study focuses on the Middle and Upper Reaches of the Yellow River Basin,analyzing the spatiotemporal evolution characteristics of urbanization levels and ecosystem service values in the region,and utilizes the Geographically Weighted Regression model to explore the impact mechanisms and dynamic changes of the urbanization subsystem on ecosystem service values.The findings indicate:(1)The region has seen a significant increase in urbanization levels,and its urban development pattern is undergoing a major transformation,forming a“multi-center,clustered”urban spatial pattern centered on central cities.(2)The ecosystem service values in the area show a steady growth trend,presenting a spatial pattern that is higher in the northwestern plateau areas and lower in the southeastern plains.(3)The impact of urbanization on ecosystem service values shows significant spatial heterogeneity.Among these,land urbanization has a significant negative impact on ecosystem service values;the impact of economic urbanization has gradually shifted from negative to positive;while population urbanization and social urbanization have both positive and negative effects.This research enriches theoretical insights into the interrelations between natural and human systems at the basin scale,and provides a scientific foundation for formulating regional development plans and ecological conservation policies,offering significant theoretical and practical values.
