摘　　要：苏锡常是我国经济飞速发展地区之一,也是重要的粮食生产基地。在快速城镇化背景下,该地区生态环境受到人类活动的强烈冲击,国土空间配置亟待优化。本研究基于多源数据,对苏锡常地区2000~2018年碳储存、食物供给、维持生物多样性3种生态系统服务的时空格局及演变特征进行刻画,并运用双变量空间自相关方法识别了生态系统服务之间的相互关系。结果表明:(1)整体来看,2000~2018年,苏锡常地区的碳储存服务略有上升,食物供给服务和维持生物多样性服务波动下降;(2)苏锡常地区生态系统服务空间分布严重失衡,表现为中部建成区低,四周自然用地高的分布特点,城镇扩张区各类型生态系统服务退化较为严重;(3)在权衡与协同分析中,碳储存-食物供给服务、碳储存-维持生物多样性服务呈现协同关系,食物供给-维持生物多样性服务呈现权衡关系;(4)各项生态系统服务的权衡与协同关系存在空间差异,低值协同区集中分布在城市中心,高值协同区主要分布在西侧与南侧林地范围,低-高值与高-低值权衡区在空间上呈环绕相间分布。苏锡常地区在未来的发展中需要注意低值协同区和权衡区,有针对性地制定生态保护修复措施,合理调控社会经济发展,实现生态系统服务的协同增效。The Su-Xi-Chang region,which is an important grain production base,and is one of China’s fastgrowing economic regions. In the context of rapid urbanization,human activities considerably threaten local ecological environments and the land space allocation must be optimized. Based on the data obtained from multiple sources,this study presents the spatial and temporal patterns as well as evolution features of three ecosystem services in the Su-Xi-Chang region from 2000 to 2018,including the carbon storage(CS),food supply(FS),and biodiversity(BD) services,and identifies the interrelations between various ecosystem services using the bivariate spatial autocorrelation method. Results indicate the following trends.(1) CS grew slightly,whereas FS and BD were in the fluctuant downward in the Su-Xi-Chang region from 2000 to 2018.(2) The spatial distribution of ecosystem services was considerably unbalanced,indicating low and high value distributions in the central built-up area and the surrounding natural land,respectively. Considerably serious degradation can be observed in case of various types of ecosystem services in urban expansion areas.(3) Through tradeoff and synergy analyses,a synergy can be observed between CS and FS as well as CS and BD,whereas a tradeoff can be observed between FS and BD.(4) Spatial differences can be observed with respect to the tradeoffs and synergies associated with ecosystem services. The low-value synergistic zone was concentrated in the city center,whereas the high-value synergistic zone was mainly concentrated in the west and south of the woodland range,with the low-high and high-low value tradeoff areas being spatially distributed around each other. In future,attention must be devoted to the low-value synergistic and tradeoff areas with respect to the ecosystem services in the Su-XiChang region. Furthermore,targeted ecological protection and restoration measures must be developed,and socioeconomic development must be rationally regulated to achieve synergy in case of ecosystem service
