摘　　要：城镇化与生态系统服务的关系是可持续发展领域的重要议题。随着人类在高原等特殊地理条件下改造自然的能力不断加强,人类活动与生态环境的交互作用关系逐渐从被动适应转变为主动协调。以城镇化为代表的经济社会发展和以生态资产价值量衡量的生态系统服务,如何在高原地区协调互促,愈加成为实现区域可持续发展目标的关键核心。论文以西藏自治区为研究区,基于2000—2020年城镇化与生态系统服务的综合水平测度,采用双变量空间自相关、耦合协调度模型、核密度估计等方法,探讨城镇化与生态系统服务的多尺度空间关联特征,判断两者的耦合协调类型及时空演变模式。结果表明:(1)2000—2020年间西藏全域城镇化呈现局部集聚的空间分布特征,年际变化的总体趋势为缓慢上升;而生态系统服务的空间分布更加分散,区际差异较大,但总体水平保持稳定。(2)城镇化与生态系统服务具有显著的空间负相关关系,城镇化综合指数高的地区,其周边地区的生态系统服务水平相对偏低。(3)以2010年为拐点,西藏城镇化与生态系统服务的交互关系具有先扩张再收缩的变化特征。目前协调发展类型和基本协调类型占据主导地位,但同时也出现失调衰退的情况。(4)耦合协调关系演变在空间上体现为,以拉萨及其周边地区的单中心主导逐步转向包含其他地市区县的多中心分布模式,这在一定程度上得益于拉萨市耦合协调发展过程的空间溢出效应。论文从空间视角完善了高原城镇化与生态系统服务的耦合协调研究,可为合理引导人地关系协调健康发展提供决策依据。The relationship between urbanization and ecosystem services is an important issue in the field of sustainable development.The relationship between human activities and the ecological environment has increasingly shifted from passive adaptation to active coordination as human potential to transform nature under unique geographical conditions such as on plateaus has been strengthened.Promoting the coordination of economic and social development(represented by urbanization)and ecosystem services(assessed by the value of ecological assets)in plateau areas is increasingly becoming critical for achieving the objective of sustainable regional development.Taking Tibet Autonomous Region as the research area,this study measured the comprehensive level of urbanization and ecosystem services from 2000 to 2020.The research methods included bivariate spatial autocorrelation,a coupling and coordination degree model,and kernel density estimation.The purpose of this study was to explore the multi-scale spatial correlation characteristics of urbanization and ecosystem services,and to identify the coupling and coordination types and spatiotemporal evolution modes of these two systems.The results are as follows:1)Urbanization in Tibet between 2000 and 2020 displayed the spatial distribution characteristics of local agglomeration,and the overall trend of interannual change was a steady increase.The spatial distribution of ecosystem services,on the other hand,was more dispersed with significant regional disparities,but the overall level remained consistent.2)There was a significant negative spatial correlation between urbanization and ecosystem services.The level of ecosystem services in the surrounding areas of places with high comprehensive urbanization index values was comparatively low.3)The connection between urbanization and ecosystem services in Tibet first grew and then weakened,with 2010 as the transition point.Currently,coordinated development is the predominant form,but there are some areas that are at risk of deterioratio
