摘　　要：维持和改善生态系统服务是保障老工业城市可持续转型的重要基础。利用遥感影像解译和改进当量因子法,定量分析沈阳土地利用时空变化及对生态系统服务价值影响。结果表明:(1)沈阳土地利用以耕地为主,建设用地和水域呈增加趋势,而草地、林地等重要生态用地逐渐减少;2005—2010年其土地利用/覆被变化最为显著。(2)生态系统服务主要以调节服务为主,耕地和水域贡献超八成的生态系统服务,而草地、林地仅贡献约两成,且逐年减少;空间分布上呈中心低外围高的圈层结构;生态系统服务价值年均增加0.66亿元,人均价值年均降低47.95元。建议系统管理城乡土地资源,加强林地、草地等保护和质量提升,控制新城区和工业园区扩张,提升单位土地资源产出率。Maintaining and improving ecosystem services is an important base for ensuring sustainable development of old industrial cities.Using remote sensing image interpretation and improved equivalent factor method,the spatiotemporal change of land use/cover in Shenyang city and its impact on ecosystem service values were quantitatively analyzed.The results showed that:(1)Arable land was the main land use type in Shenyang,construction land and water area were increasing,while grassland,woodland and other important ecological land were decreasing;the time that the land use/cover change was the most significant was from 2005 to 2010.(2)The ecosystem service values were mainly from regulated services,arable land and water area contributed over 80.00%of the service values,while grassland and woodland contributed only 20.00%,which were also declining annually;the spatial pattern of ecosystem service values in Shenyang presented a circle layer structure,the ecosystem service values in central location was lower and in peripheral areas was higher.The ecosystem service values in Shenyang increased by 66 million Yuan per year on average,and the value per capita decreased by RMB 47.95 Yuan per year on average.It is suggested to systematically manage urban and rural land resources,strengthen the protection and quality improvement of forest land and grassland,control the expansion of new urban areas and industrial parks,and improve the output rate of unit land resources.
