摘　　要：[目的]定量分析城市化进程中泰安市岱岳区生态用地变化对生态服务价值变化的影响,为该区域科学合理地规划生态用地布局、提高人居环境质量提供理论依据和决策支持。[方法]利用遥感技术和地理信息系统,获取并分析泰安市岱岳区2000和2010年2期的卫星影像数据。[结果]2000—2010年岱岳区生态用地总面积减少了183.76 hm2;生态系统服务价值总量减少了2.83×106元,其中水域减少的最多,达17.19×106元。[结论]林地生态系统和水域生态系统对生态系统服务价值影响较大,是影响该区域整个生态系统服务价值变化的重要子系统。因此,合理规划生态用地的结构和布局,特别是林地和水域布局,可有效地提高生态系统服务价值。[Objective]Effects of eological land use changes on ecosystem services values were quantitatively analyzed during urbanization process in Daiyue District of Tai＇an,which provides theoretical basis and decision support for the scientific and rational planning of ecological land use and improving the quality of human settlements.[Method]Two remote sensing images of Daiyue District in Tai＇an in 2000 and 2010 were analyzed with the aid of GIS and RS.[Result]From 2000 to 2010,the total area of ecological land in Daiyue District decreased by 183.76 hm2; the total value of ecosystem services decreased by 2.83×106 yuan,of which waters decreased the most,reaching 17.19×106 yuan.[Conclusion]Forest ecosystems and water ecosystems have a significant impact on the value of ecosystem services and are important subsystems that affect the value of ecosystem services throughout the region.Therefore,rational planning of the structure and layout of ecological land,especially the layout of forest land and waters,can effectively improve the value of ecosystem services.
