摘　　要：生态系统服务间存在复杂的权衡或协同关系并表现出显著空间异质性,明确生态系统服务权衡与协同关系的空间分异特征并阐明其驱动因素,对生态系统可持续规划与管理具有重要意义。利用InVEST模型和城市生态智慧管理系统(IUEMS)量化2020年长株潭城市群6项关键生态系统服务物质量(水源涵养(WC)、土壤保持(SC)、碳固存(CS)、生境质量(HQ)、粮食供给(FP)和景观美学(LA)),并运用相关系数法揭示1 km格网尺度的生态系统服务权衡与协同关系及其空间分异特征,最后通过逻辑斯蒂回归分析阐明其驱动因素。结果显示,1)2020年长株潭城市群SC、WC、CS、HQ和LA均呈现东南高西北低的空间分布特征,FP呈现西北高东南低的分布特征。2)长株潭城市群生态系统服务间权衡与协同关系空间差异明显。SC与CS、WC、HQ、LA间协同关系面积占比超过60%,协同关系主要分布在研究区东北部和南部的山区以及西部农田地区,而权衡关系主要位于建成区及其周边地区。FP与CS、WC、HQ、LA间权衡关系面积占比超过65%,权衡关系主要位于北部的平原区域和南部的山区,而协同关系主要位于城市区域及其周边非林地区域。3)自然、社会经济和政策管理因素共同影响生态系统服务间权衡与协同关系的空间异质性。陡坡会抑制生态系统服务之间的协同;温度、降水、NDVI的增加能够促进调节服务、支持服务和文化服务间的协同,但抑制FP与其他生态系统服务间的协同;社会经济发展会促使生态系统服务间趋向低-低协同或权衡关系;绿心保护政策促进SC与其他生态系统服务,以及CS与LA之间的协同。Different types of ESs have intricate trade-offs or synergies,and these relationships exhibit strong spatial heterogeneity.Understanding spatial heterogeneity and its driving factors is important for sustainable ecosystem planning and management.Using the Changsha-Zhuzhou-Xiantan Urban Agglomeration(CZTUA)as the study area,we first quantified six important ESs(water conservation(WC),soil conservation(SC),carbon sequestration(CS),habitat quality(HQ),food production(FP),and landscape aesthetics(LA))in 2020 using the InVEST model and the Intelligent Urban Ecosystem Management System(IUEMS).Then,the correlation coefficients between these ESs were estimated for each 1 km grid to investigate the trade-offs or synergies and their spatial patterns.Finally,logistic regression analysis was used to identify the factors influencing trade-offs or synergies between ESs.The results showed that 1)the spatial patterns of SC,WC,CS,HQ,and LA were high in the southeast and low in the northwest,whereas FP was high in the northwest and low in the southeast in 2020.2)The trade-offs or synergies between ESs are spatially heterogeneous in the CZTUA.More than 60%of the study area showed synergistic relationships between SC and CS,SC and WC,SC and HQ,SC,and LA,which were mainly distributed in northeastern and southern mountainous areas and western farmlands.Trade-offs between ESs were mainly found in built-up areas and their peripheries.Trade-offs between FP and CS,FP and WC,FP-HQ and FP,and LA covered over 65%of the study area,mainly in the northern plain and southern mountainous areas,and were primarily found in urban and surrounding non-forested areas.3)The spatial heterogeneity of trade-offs and synergies between ESs is influenced by natural and socioeconomic factors as well as management policies.Synergies between ESs are hindered by steep areas.Synergies between regulating,supporting,and cultural services were promoted by increases in temperature,precipitation,and NDVI.However,synergies between FP and other ESs showed opposite respon
