摘　　要：采用1990、2000、2010及2018年四期长江经济带土地利用类型遥感影像解译数据,在ArcGIS10.7和GeoDa1.6等软件的支撑下,利用谢高地等构建的生态系统服务价值化方法,测算研究区土地生态系统服务价值,再运用空间自相关分析法,研究长江经济带土地生态系统服务价值的空间相关性及内部异质特征。结果表明:①长江经济带林地、水田、旱地、草地及未利用地面积持续减少,湿地及建设用地面积持续增加,河流湖泊面积先减少后大幅度增加,导致长江经济带土地生态系统服务价值总体上呈先减少后增加态势。②水田、旱地、草地及林地生态系统服务价值在整个研究区间内均呈逐步减少态势,是土地生态系统服务价值减少的根本原因;湿地生态系统服务价值在整个研究区间内呈稳步增加态势,河流湖泊生态系统服务价值在2010年之后大幅度增长,是土地生态系统服务价值由减少转变为增加的主要原因。③研究期内长江经济带土地生态系统服务价值分布具有较为显著的空间正相关性,且呈逐渐增强态势。④研究期内长江经济带土地生态系统服务价值的空间分布格局变化明显,其中高—高集聚区由四川省逐渐扩展到云南省,区域数量逐渐增加;低—低集聚区主要由浙江省转移到江苏省;低—高集聚区和高—低集聚区变化不明显。Based on the remote sensing image interpretation data of land use types in the Yangtze River Economic Belt in 1990,2000,2010 and 2018,supported by software such as ArcGIS10.1 and GeoDa1.6,the value of land ecosystem service in the study area is calculated by using the value-added method of ecosystem serviceconstructed by XieGaodi,etc.Then,the spatial autocorrelation analysis method is used to study the spatial correlation and internal heterogeneity of land ecosystem service value in the Yangtze River Economic Belt.The results show that:(1)The area of forest land,paddy field,dry land,grassland and unused land in the Yangtze River Economic Zone continued to decrease,the area of wetland and construction land continued to increase,and the area of river and lake first decreased and then increased significantly,which led to the overall decrease and then increase of land ecosystem service value in the Yangtze River Economic Zone.(2)The ecosystem service value of paddy field,dry land,grassland and woodland decreased gradually in the whole study area,which is the basic reason for the decrease of land ecosystem service value;the ecosystem service value of wetland increased steadily in the whole study area,and the ecosystem service value of river and lake increased significantly after 2010,which is the main reason why the value of land ecosystem service has changed from decreasing to increasing.(3)During the study period,the distribution of land ecosystem service value in the Yangtze River Economic Belt had a significant spatial positive correlation,and it gradually increased.(4)The spatial distribution pattern of land ecosystem service value in the Yangtze River Economic Belt changed significantly during the study period.The high-high concentration area gradually expanded from Sichuan Province to Yunnan Province,and the number of areas gradually increased;the low-low concentration area mainly transferred from Zhejiang Province to Jiangsu Province;the low-high concentration area and high-low concentration area did not chang
