摘　　要：指出了研究土地利用变化对区域生态系统服务价值的影响具有重要的意义。以山东半岛中心城市群6期土地利用数据为基础,探讨了区域内2009~2014年间土地利用变化及其所引起的生态系统服务价值的变化。结果表明：该区水域、耕地和林地是主要的土地利用类型,农田面积基本保持不变,而未利用地面积逐渐减少;研究期内生态系统服务价值总体呈“下降-上升-下降”的趋势。林地、耕地和水域是生态系统服务价值构成中贡献最大的土地类型,占到总生态系统服务价值的90%以上。To study the influence of land use change is of great significance for regional ecosystem service value. Based on the 6--period land use data of the central urban agglomeration in Shandong Peninsulacentral city groups, this paper discussedthe land use change and the ecosystem service value caused byitfrom 2009 to 2014 in the region. The results showed that the water, land and forest in this area were the main land use types, farmland area remained basically unchanged, and the unused land decreased graduallY; during the research period, the value of ecosystem services was showing a ＂down up down＂ trend. Woodland, cultivated land and water area were the largest land types in the ecosystem services value, accounting for more than 90% of the total ecosystem services value.
