摘　　要：采用全国土地分类系统,基于Landsat卫星TM遥感影像与天津滨海新区1∶50 000地形图,进行相应数据处理,编制出2000年、2005年、2010年三期滨海新区土地利用/覆盖分类图,并运用土地利用转移矩阵对近10年来天津滨海新区土地利用/覆盖变化进行定量分析。在此基础上,进一步分析了经济、人口等驱动因子对土地利用/土地覆盖的影响。结果表明:10年间,滨海新区的建筑用地面积增加显著,而绿地、湿地、滩涂等高生态价值的土地向建筑用地、未利用地等开发建设用地大幅度转化,后5年变化尤为显著。Using the National Land Classification System and based on Landsat TM satellite remote sensing image and the Tianjin Binhai New Area 1：50 000 relief maps, three stages （2000, 2005 and 2010） of land use/cover classification maps for Binhai New Area were drafted, and using the transition matrix of land use for nearly 10 years of land use/cover change in Tianjin Binhai New Area, the quantitative analysis was made. On this basis, the impacts of driving factors, such as economy and population on the land use/cover were further analyzed. The results showed that： over the ten years, in Binhai New Area, the construction land＇s area increased significantly, and the green land, wetland and beaches with high ecological value increasingly transformed into the construction land and unused land for development and construction, and it became more significant in later five years.
