长沙市土地利用动态变化及其驱动力因素分析

摘要

Based on the detailed land use change data of Changsha City from 1996 to 2007, the land use status, dynamic variation and its driving factors were analyzed in time and space. The results showed that the area of agricultural land and unused land reduced greatly, while that of construction land increased significantly during the study period. The variation was greater in the last six years compared to that in the former six years.%根据长沙市1996～ 2007年土地利用变更数据资料,从时间和空间视角对长沙市的土地利用及其动态变化状况进行分析,并对影响其变化的主要驱动因子进行剖析.结果表明,12年间长沙市农用地和未利用地面积大幅减少,建设用地面积大幅增加,后6年的变化幅度明显大于前6年.
