土地利用/覆被变化通过改变生态系统的结构与功能，进而对生态系统服务的供应产生影响。以厦门市为研究区域，引入土地利用强度指数，分析当地土地利用/覆被变化过程；将研究区划分为农田、森林和湿地三个生态系统，参考已有研究成果，构建生态系统服务价值评估模型，探讨区域整体服务价值的演变过程；并通过土地系统和生态系统二者的耦合变化关系探讨土地利用/覆被变化对生态系统服务的影响过程。结果表明：近20 年来，厦门市生态系统服务价值总量随土地利用强度的增强呈现逐年增加的趋势，由1987 年的34.8 亿元增加到2007 年的39.0 亿元，供给服务和调节服务是最主要的生态系统服务类型；土地利用强度的变化与供给服务和文化服务呈现正相关关系，而与调节服务和支持服务呈现负相关关系。

Through changing ecosystem's internal structure and function, land use/cover change (LUCC) has affected the supply of ecosystem services. Taking Xiamen City in southeastern China as a study area, this paper used a land use intensity model to analyze regional land change processes. Furthermore Xiamen area was divided into three ecosystems: farmland, forests and wetlands, the ecosystem service evaluation model was developed through combining material and value assessment methods; the coupling changes between land systems and ecosystems were used to represent the influences of land use/cover change on natural ecosystems. The results suggested that along with the promotion of land use intensity, the total ecosystem service values increased from 3.48 billion yuan (RMB) in 1987 to 3.90 billion yuan (RMB) in 2007, with supplying and regulating service being main ecosystem service types; land use intensity had positive relationship with supplying and cultural services, while it was negative for regulating and supporting services.
