摘　　要：[目的]评估城镇化和生态恢复双过程共同作用下生态系统服务价值(ESV)的变化量,揭示京津冀城市群城镇化与生态建设对ESV的影响,进而为区域协调发展及可持续发展决策提供理论参考。[方法]以京津冀城市群为研究区,基于1995—2020年的土地利用/覆盖、社会经济统计等数据,识别区域城镇扩张与生态建设信息,并结合生态系统服务单位面积价值当量因子法、空间自相关以及冷热点分析等方法,展开了城镇化与生态建设双过程对区域ESV在时空尺度上的影响研究。[结果](1)京津冀城市群ESV在1995—2020年总体下降,呈现出先下降后上升的趋势,2015—2020年生态环境明显好转。(2)城镇扩张所导致的城镇建设用地占用其他地类是使ESV下降的主要因素,使区域ESV降低了368.2亿元;生态建设使区域ESV上升了225.67亿元。[结论]生态建设带来的ESV增量不足以抵消城镇化带来的下降。城镇化与生态建设对ESV影响较强的地区主要分布在城市群的西部和东北部,对ESV影响较弱的地区主要分布在城市群的东南部。[Objective]The aims of this study are to assess the amount of change in ecosystem service value(ESV)under the combined effect of the dual processes of urbanization and ecological restoration,to reveal the impact of urbanization and ecological construction on ESV in the Beijing-Tianjin-Hebei urban agglomeration,and then to provide theoretical references for decision-making on coordinated regional development and sustainable development.[Methods]This study takes the Beijing-Tianjin-Hebei urban agglomeration as the study area,identifies regional urban expansion and ecological construction information based on land use/cover and socioeconomic statistics from 1995 to 2020.We also combine the ecosystem service unit area value equivalent factor method,spatial autocorrelation and cold hotspot analysis to develop a study on the impact of the dual process of urbanization and ecological construction on regional ESV at spatial and temporal scales.[Results](1)The ESV of the Beijing-Tianjin-Hebei urban agglomeration generally declined from 1995 to 2020,showing a trend of first decline and then increase,and the ecological environment improved significantly from 2015 to 2020.(2)The occupation of other land types by urban construction land caused by urban expansion was the main factor that made ESV decrease,which made regional ESV decrease by 36.82 billion yuan;ecological construction made regional ESV increase by 22.567 billion yuan.[Conclusion]The increase in ESV due to ecological construction was not enough to offset the decrease due to urbanization.The regions with stronger impact of urbanization and ecological construction on ESV are mainly located in the western and northeastern parts of the urban agglomeration,and the regions with weaker impact on ESV are mainly located in the southeastern part of the urban agglomeration.
