摘　　要：探讨“空间-经济-人口”碳强度与生态系统服务的时空互动关系,可有效揭示土地利用变化下人类社会发展与自然生态间的关联及演进差异,为“双碳”目标下区域全面高质量发展提供参考.以黄河流域山东段为例,测算其县级尺度2000~2020年生态系统服务以及空间、经济和人口等3个维度的碳强度,构建互动弹性指数(IEI)量化各维度碳强度与生态系统服务的时空互动关系,并探讨多维互动分区格局和对策建议.结果表明:①空间碳强度和人口碳强度主要为正向变化,经济碳强度存在较大负向变化;生态系统服务综合指数高值集中在东部,指数整体呈增加态势.②2005~2010年,空间和人口碳强度与生态系统服务的互动关系为生态绝对下降,2010~2020年生态绝对上升关系增多,经济碳强度与生态系统服务的互动关系以生态隐形上升为主.③多维互动分区格局具有显著的时空变化特征,三维理想互动区数量在2010~2015年最多,二维不理想互动区是最广泛的分区类型.多维时空互动分析可从多维度探究区域发展状况,黄河流域山东段目前“空间-人口”不理想互动区较多,绿色低碳转型效果不明显,生态系统服务提升欠佳,仍需改善.Exploring the spatio-temporal interactions between“spatial-economic-demographic”carbon strength and ecosystem services can effectively reveal the correlation and evolutionary differences between human social development and natural ecology under land-use change and provide a reference for comprehensive and high-quality development in the region under the goal of“double carbon.”Taking the Shandong Section of the Yellow River Basin as an example,ecosystem services and carbon strengths of spatial,economic,and demographic dimensions were measured at the county scale from 2000 to 2020,the interaction elasticity index(IEI)was built to quantify the spatio-temporal interactions between each dimension's carbon strengths and ecosystem services,and the pattern of multi-dimensional interaction zoning and countermeasure suggestions were explored.The results showed that:①The spatial and demographic carbon strengths were mainly changed positively,whereas the economic carbon strength was more negatively changed;the high values of the composite index of ecosystem services were concentrated in the east,and the index showed an overall increasing trend.②The interaction between spatial and demographic carbon strength and ecosystem services was an ecological absolute decline relationship from 2005 to 2010,the ecological absolute increase relationship increased from 2010 to 2020,and the interaction between economic carbon strength and ecosystem services was dominated by an ecological invisible increase relationship.③The pattern of multi-dimensional interaction zoning was characterized by significant spatial and temporal variations,with the number of three-dimensional ideal interaction zones being the highest from 2010 to 2015,and twodimensional undesirable interaction zones being the most widespread type of zoning.Multi-dimensional spatio-temporal interaction analysis could be used to explore the regional development situation from multiple dimensions,and the Shandong Section of the Yellow River Basin had more“spatial-d
