中国快速的城市化进程加剧了土地利用的变迁，严重威胁着生态系统。现有文献缺乏关于土地利用变化的时空分析的信息，生态系统服务评估仍然不完整。这种信息的缺乏可能会限制景观规划和生态政策的制定和执行。本研究试图填补这一空白，通过分析的地理特征的土地利用变化的地学信息图谱方法，探讨生态系统服务的响应。利用Landsat增强型专题制图仪（ETM）获取的长江中游经济带土地利用/土地覆盖变化数据，提出了一种新的效益转移方法。结果表明，1995 - 2015年，建设用地面积持续显著增加，耕地面积持续下降。建设用地增加主要是占用耕地。“林地>耕地”、“耕地>林地”、“耕地-水域”和“水域-耕地”的图谱单元是影响生态系统服务价值变化的主导驱动力。1995-2005年和2005-2010年ESV变化的热点主要位于周边山区，2010-2015年ESV变化的冷点主要位于平原地区。本研究结果对该区域生态系统保护、生态功能区划、生态补偿决策及相关土地开发具有重要的指导意义。(C)2019爱思唯尔B.

Rapid urbanization in China has greatly exacerbated land use transitions (LUTs), which seriously threaten the ecosystem. The existing literature lacks information on the spatio-temporal analysis of LUTs, and assessments of ecosystem services remain incomplete. This lack of information may limit the formation and implementation of landscape plans and ecologically oriented policies. This study attempts to fill this gap by analysing the geographic features of LUTs with the geo-informatic Tupu method and exploring the responses of ecosystem services to LUTs. A newly revised benefit transfer method that utilizes the land use/land cover change data derived from the Landsat Enhanced Thematic Mapper (ETM) in the Middle Reaches of the Yangtze River Economic Belt (MRYREB) is implemented. The results indicate that the area of construction land continued to increase markedly, while the area of cultivated land declined continuously from 1995 to 2015. This increase in construction land was mainly derived from the occupation of cultivated land. The Tupu units of "forestland > cultivated land," "cultivated land > forestland," "cultivated land -> water area," and "water area -> cultivated land" were the dominant driving forces of the changes in ecosystem services value (ESV) in the MRYREB. Hotspots of ESV changes were mainly located in the surrounding mountainous areas during 1995-2005 and 2005-2010, while the coldspots during 2010-2015 were mainly located in the plains. The findings in this study have important implications for ecosystem conservation, ecological function zoning, ecological compensation decision-making, and related land development in the MRYREB.
