摘　　要：以天津市滨海新区为例,利用遥感影像分析其1984年-2008年间土地利用变化,并讨论其驱动力及对渤海湾的影响。结果表明:从1984年-2012年间,盐地减少342.95 km2,建设用地的面积增加1 105.04 km2。发生这种转变的驱动力主要是人口增加、经济发展和土地政策调整。土地利用类型的转变导致人为活动方式发生改变,工业迅速发展,最终导致渤海湾沉积物中营养盐含量和重金属含量增加。Taking Tianjin Binhai New Area as an example, this study analyzes the change of land -use type from 1984 to 2008 using remote sensing image. Driving forces for the change and its influence on the water environment of Bohai Bay have been also discussed. The results indicate that, from 1984 to 2008, the area of saline land decreased by 342. 95 km^2 , and the area of construction land increased by 1105.04 km^2. Major forces for the change of land - use type are the increase of population, the development of economy, and the adjustment of land - use policy. The change of land - use type also leads to the change of human activities and the rapid development of the industries, which increase the content of the nutrient and heavy metals in the sediments of the Bohai Bay.
