利用环渤海区域1998，2000，2003，2005，2007年份的分县土地利用详查变更数据，选取耕地、园地、林地、牧草地、水域、城乡居民及工矿用地和未利用地等土地利用类型，在GIS技术与定量模型支持下，进行了环渤海区域不同时段及其内部不同区域土地利用类型变化格局的模拟和分析。结果表明：1998-2007年，环渤海区域水域、耕地减少幅度较大；土地利用类型变化动态度为0．93％；环渤海区域土地利用变化存在明显的区域差异。
英文摘要：
Based on the land-use databases updated with survey of 1998, 2000, 2003, 2005 and 2007, this paper stimulates and analyzes the land-use change in the area around Bohai bay with the aid of GIS technology and quantitative models, targeting land-use types of cultivated land, garden plots, forest land, pasture land, water area, residential quarters and industrial and mining land and unused land. The outcome indicates that the water area and the cultivated land had largely decreased from 1998 to 2007 and the degree of land-use change over the last decade was 0.93 % and land-use change in the area around Bohai bay had obvious spatial differentiation, by Liaoning, while Shandong had the lowest.
