摘　　要：根据 1 985和 1 995年 2期 TM影像资料 ,运用遥感影像机助解译方法、地理信息系统空间分析方法以及数理统计方法 ,全面分析了环渤海地区 3省 2市 1 985～ 1 995年间分类土地利用的数量变化和空间变化特征。揭示了该区各类土地利用数量变化的幅度、速度和区域差异以及土地利用空间变化的主要类型、分布特征和区域方向。阐明了该区土地利用变化的区域特点 。Regional land use change is an important part of global change The Bohai Rim is one of the hot spots for socio economic development in China, so the land use change will be improved greatly Based on the RS and GIS methods, we analyze the land use information from 1985 and 1995 TM images, then in both spatial and temporal aspects, we analyze the situation of land use change in the region It is found: (1) The land use changed greatly in the Bohai Rim during 1985～1995 The cultivated land decreased by 1 800 000 hm 2, forestland increased by 600 389 hm 2 and land for housing and other construction purposes increased remarkably in the last ten years (2) The speed of the land use change in the region was up to 0 85% per year The cultivated land decreased at the rate of 1 26% per year, land for housing and other construction purposes, water area, and forestland increased at different rates, among which land for housing and other construction purposes and water area were the highest (up to 6 40% and 6 95% per year respectively) (3) There were notable differences of land use change among the sub areas in the region For cultivated land change, Beijing and Liaoning Province (partly) was the greatest, Hebei Province the smallest For land for housing and other construction purposes, Liaoning (partly) was the greatest, Beijing the second, Tianjin the smallest in land use change (4) As to the spatial change, 30% of the area in the region was under the changing process, major types of which were cultivated land turned to be land for housing and other construction purposes, and cultivated land turned to be forestland and grassland Those types of land were distributed widely and differently in different areas, but mostly near the mountains and in areas joining the town and country (5) The direction of land use change in the region was to occupy cultivated land for and convert land between forest and cultivated land at different units into that for housing and other contruction purposes
