摘　　要：借助In VEST模型对长江三角洲城市群2000~2020年生境质量(HQ)、碳储存(CS)、产水服务(WY)3种生态系统服务的时空格局及演变特征进行刻画,并采用差异比较法进一步探究生态系统服务之间的权衡与协同关系,最后利用地理加权二元逻辑回归分析自然因素和社会因素对生态系统服务间权衡协同关系的空间异质性.结果表明:(1)2000~2020年,长江三角洲城市群生境质量与碳储存均呈现下降的趋势,生境质量下降幅度为3.85%,碳储存下降幅度为0.51%;产水服务在2000~2020年间变化较大,总体增加87.56%.(2)2000~2020年,长江三角洲城市群3对生态系统服务均存在较强的时空异质性.产水服务-生境质量及产水服务-碳储存以权衡关系为主,生境质量-碳储存整体呈现协同状态.(3)建设用地面积和年平均温度变化相比于其他因子而言,对生态系统服务权衡协同的空间非平稳响应更加强烈.总之,长江三角洲城市群3种生态系统服务之间协同与权衡具有显著的时空异质性,且影响因素的正负性及强度也具有时空异质性.The Invest model was first employed to quantify the three ecosystem services,including habitat quality,carbon storage,water conservation,in the Yangtze River Delta Urban Agglomeration.Then,the trade-offs and synergies of these three ecosystem services were explored.Finally,the spatially non-stationary relationships between ecosystem services and influential factors were examined using geographically weighted logistic regression.(1)two ecosystem services in the study area experienced a decline from 2000 to 2020,with a decrease of 3.85%in habitat quality and a decrease of 0.51%in carbon storage,while water conservation underwent significant changes,with a large increase of 87.56%;(2)spatial heterogeneity was observed in the relationships among the three ecosystem services.Specifically,trade-offs were found between water conservation and habitat quality,as well as between water conservation and carbon storage,while synergies were observed between habitat quality and carbon storage;and(3)compared with other factors,the construction land area and the annual average temperature change exerted much stronger influence.In summary,the obvious spatial heterogeneity in both the trade-offs and synergies of ecosystem services and the influential factors was observed.
