摘　　要：顺德社会经济综合实力雄厚,近10年来顺德区在快速城市化的过程中显著地改变了土地利用在类型和空间分布上的结构。利用遥感(RS)和地理信息系统(GIS)技术能有效监测城市化进程中土地利用的变化。应用2000年、2010年2个时相的遥感数据,结合生态服务价值评估方法对顺德区近10间的土地利用和生态服务价值演变进行了定量评估。结果表明:2000—2010年研究区的建设用地面积增加了49.17%,观测期内研究区增加的建设用地主要来源于基塘地、林地、耕地等生态用地,各种土地类型之间的动态变化较大;顺德区城市生态服务价值由2000年的1472.95×106元减少到2010年的786.08×106元,总生态服务价值减少了686.87×106元,城市生态环境受到极大的损害。论文客观、准确地反演了研究区土地利用的动态变化过程,并基于土地利用面积估算了城市生态系统服务价值,对城镇土地综合开发管理和生态可持续发展具有一定的理论和现实意义。Shunde with the social and economic comprehensive strength, land use types and spatial distribution structure has been changed significantly nearly 10 years, in the process of rapid urbanization. Remote sensing（RS） and geographic information system（GIS） technology can effectively monitor the change of land use. Using two phases of remote sensing data of 2000 and 2010, combined with the ecological service value evaluation methods, we quantitatively evaluated the Shunde land use and ecological services value. The results showed that from 2000 to 2010, the area of construction land increased by 49.17% in the study area, which was mainly derived from ecological land, such as dike-pond land, forest land, cultivated land. Meanwhile, various land types have significant dynamic change. Moreover, in these 10 years, Shunde City ecological service value decreased by 686.87×10^6 yuan, and urban ecological environmental degradation was very serious. This research shows the dynamic change of land use in the study area, and based on land use area data it estimates the urban ecosystem service value. These results have a certain theoretical and practical significance in the comprehensive development of urban land management and ecological sustainable development.
