摘　　要：基于土地利用变更调查数据,研究长株潭城市群区域土地利用变化及其驱动机制。结果表明:1996-2005年,区域耕地、居民点及工矿用地变化幅度较大,交通用地变化较快。人类活动对区域土地利用干扰度较强,且有增强趋势。各地类重心分布发生一定偏移,耕地、居民点及工矿用地、交通用地重心偏移较明显,有向北移动趋势。人口、经济、政策等人文因素是区域土地利用变化的主要驱动因素,人为影响程度是区域土地利用空间格局变化的主要驱动力。This paper analyzes the land use change and its driving mechanism in the area of Changsha-Zhuzhou-Xiangtan megalopolis, on the basis of the detailed survey data of land use. The result shows that great change of land use occurred in this area from 1996 to 2005, with the change of cultivated land, residential land, industry and mining land quantity being more dramatic, and the change of transportation land much faster. Strong disturbance of the human activities to the land in this area is inclined to strength. The gravity centers of cultivated land, residential land, industry and mining land have shifted towards the north obviously. The factors such as population, economy and policy have played an important role in the process of land use change in this megalopolis area.
