以我国北方典型海岸带———天津滨海新区为研究区，利用1990，1995，2000和2008年4期遥感影像数据，将土地利用类型分为6大类，通过计算土地利用类型动态度、土地利用转移矩阵和土地类型空间格局重心变化3种指标模型，利用GIS和地统计学，分析了我国北方典型滨海带1990—2010年4期土地利用变化的程度、速度、扩张形式和时空格局的变化．结果表明，近20年来我国北方滨海带———天津滨海新区正处于土地利用发展时期，水域面积减少了233.04 km2，而建设用地逐年扩张，且其动态度达9.58％；同时水域、耕地和未利用地不断转为建设用地．滨海新区土地利用时空格局的变化主要源于政策导向和经济的不断发展．

As a typical coastal belt of northern China ,Tianjin Binhai New Area (TBNA) has been divided into six categories of land use types ,based on TM images of the years of 1990 ,1995 ,2000 and 2008 . Temporal and spatial differences and expansion pattern of land use in TBNA are determined with GIS soft-ware for calculating land-use dynamic index ,conversion matrix ,spatial pattern center ,change degree and extent .Results show that land use pattern significantly changed from 1990 to 2008 ,characterizing by de-crease of water area and large increase of built-up land .Meanwhile the water area reduced 233 .04 km2 in recent 20 years and the dynamic index of built-up reached 9 .58% .Increased built-up lands dominantly came from water areas and partly from farmlands and unutilized lands .Only a small amount of grasslands were changed to built-up lands ,which indicates that TBNA was in the period of land use development . Spatio-temporal changes in land use pattern were mainly due to policy guidance and continuous economic development .
