	为研究南四湖流域土地利用时空变化对生态系统服务功能的影响，基于1990~2015年间的六期Landsat数据，了解土地利用时空变化情况，并结合生态系统服务价值当量分析该时段南四湖流域生态系统服务价值量的变化，最后运用灰色关联理论分析了土地利用类型变化与生态系统服务价值的关系。结果表明，近26年来南四湖流域各土地利用类型的面积变化显著，建设用地面积增加量较大，未利用土地面积减少量较大；研究区域生态系统服务价值量呈先增加后减少的趋势；耕地、林地的减少与建设用地量的增大是该区域自1995年起生态系统服务价值总量持续减少的主要原因；建设用地和林地的生态系统服务价值对生态系统价值总量的影响最大，而水域和未利用土地对生态系统服务价值总量的影响性最小。<br />
In order to study the effect of the change of land use on the ecosystem service value in the Nansi Lake Basin, this paper studied the features of the change of land use from 1990 to 2015 firstly; then the change of ecosystem services value was analyzed combined with equivalent of ecosystem services value. The relationship between land use change and ecosystem service value was analyzed by gray relational theory in the last. The results showed that all of the land use types in the Nansi lake basin has transformed significantly in the past 26 years; the extend of the land used by construction was remarkable; the unused land area decreased. The tendency of Ecosystem Services Value climbed up and then declined. The plough and forest land’s contract was the most reason for Ecosystem Services Value’s sustainable reduced which after 1995. The Ecosystem Services Value created by forest and construction land influenced the total value outstanding and the value created by water area and unused land affected the total value rarely.<br />
