摘　　要：根据2003年、2009年遥感数据,从数量结构、空间格局和类型转换3个角度对湖南醴陵市土地利用动态变化进行了定量分析,研究结果表明:6a来,醴陵市旱地与园地面积锐减,林地面积大幅度增加,城乡居民工矿用地逐年增加;醴陵市土地利用景观变化的强度和方向在不同地貌区存在明显差异,岗丘区和低山丘陵区的土地利用变化较大,而山地区的土地利用变化相对缓慢;土地利用类型转换主要表现为水田、旱地、园地、林地转变为城乡居民工矿用地,水田、旱地、园地和未利用地转换成林地,园地转换为旱地,未利用地单向转移,新增建设用地主要分布在丘岗区、低山丘陵区,而林地增加主要集中在北部山地区。醴陵市经济发展必须重视和解决经济发展与农地保护间的矛盾,为长株潭城市群发展提供可持续的区域性生态保障。Dynamic change of land use in Liling city was analyzed from the view of quantity,spatial pattern,and transformation based on the remote sensing images data of Liling City in 2003and 2009.The results indicated that the area of dry land and garden land decreased rapidly from 2003to 2009,forestland area increased significantly,urban and rural mining land increased year by year.The landscapes of land use had changed greatly in different landform areas which land use in plains and hilly has changed more greatly than the mountainous area.The paddy field,dry land,garden land and forestland converted to urban and rural residents,and paddy field,dry land,garden land and unused land converted to forestland,garden land converted to dry land,one-way transfer of unused land,new construction land mainly distributed in the hilly area and plain area,while forecastland increased mainly in the northern mountain region.Therefore,it was a significant issue to solve the conflicts between agricultural land protection and economic development,and environmental protection must be strengthened to provide the ecological security for regional sustainable development of Changsha-Zhuzhou-Xiangtan urban agglomeration.
