摘要
以张家界市永定区为例,利用其土地利用现状及变更调查数据,历年社会经济统计资料,分析了1996～2005年湘西北喀斯特山区土地利用变化过程与特点,并定量分析了土地利用变化的主要驱动因素。研究结果表明:十年间,研究区耕地、其他农用地和未利用地面积逐渐减少,园地、林地和建设用地面积有所增加;土地利用程度较高,但整体综合指数不稳定,正处于土地利用的调整时期。人口增长、经济和旅游业的发展是影响湘西北喀斯特山区耕地变化的主要驱动因素。
We take Yongding district of Zhangjiajie as the study case,which locates in Karst mountain areas of Northwestern Hunan,China.Using land use data and corresponding socio-economic statistical dada in study area from 1996 to 2005,land use change and its driving forces are analyzed quantitatively.The results indicate that ：（1） during study period cultivated land and other agricultural land were decreased significantly,while construction land,garden land and woodland were increased correspondingly;（2） land use change rate was relatively high,and was in an adjusting period of land use change;（3） the driving forces affecting cultivated land change were demographic,economic development and the local tourism development.
