摘　　要：论文基于2000-2020年五期土地利用数据,定量分析长江三峡生态经济走廊生态系统服务价值的时空演化特征,采用空间相关、时空地理加权回归模型分析驱动力。结果表明:(1)从土地利用类型来看,森林是研究区域最主要的土地利用类型,建设用地与未利用土地是两种变化较快的土地利用类型;(2)从时空演化上看,该区域在2000-2020年时间段内的生态系统服务价值呈先增后减的趋势,生态调节服务始终是核心功能,气候调节的贡献率最大;空间分布呈现中部地区高、西部地区和东部边缘低的布局;(3)生态系统服务价值的正向空间相关性逐渐增强,中部区域巫溪县、云阳县等九个区县为高一高聚集区,东部西陵区、伍家岗区、亭区、点军区及垫江县为低一低聚集区,东部夷陵区为高一低聚集区,南部黔江区、秀山县为低一高聚集区;(4)影响因素中,蔓延度指数、斑块密度、斑块聚合度、第三产业占CDP比重、人均GDP影响在42个区县中呈现差异化表现,其中人均CDP负向影响程度最大。Based on the five periods of land use data from 2000 to 2020,this study quantitatively analyzes the spa-tial and temporal evolutionary characteristics of ecosystem service values of the Three Gorges Ecological Economic Cor-ridor of the Yangtze River,and uses the spatial correlation and spatiotemporal geographic weighted regression model to analyze the driving force.The results showed that:(1)In terms of land use type,forest is the main land use type in the study area,and construction land and unused land are two types of land use that change rapidly.(2)In terms of spatial and temporal evolution,the value of ecosystem services in the region shows a trend of increasing and then decreasing in the 2000-2020 time period,with ecological regulation services always being the core function and climate regulation making the largest contribution;The spatial distribution show a layout of high in the central region and low in the west-ern and eastern edges.(3)The positive spatial correlation of ecosystem service value is gradually increasing.The central region is a high-high agglomeration area,including nine districts and counties such as Wuxi and Yunyang coun-ties.Eastern Xiling,Wujiagang,Xiaoting,Dianjun and Dianjiang districts are a low-low agglomeration area.The eastern Yiling district is a high-low agglomeration area,while the southern Qianjiang and Xiushan are low-high aggregation ar-eas.(4)Among the influencing factors,the effects of sprawl index,patch density,patch aggregation,the proportion of tertiary industry to GDP,and GDP per capita show differential performance among 42 counties(districts),with GDP per capita having the greatest negative influence.
