| 摘 要： | 基于甘肃省1997~2004年统计资料和土地详查与变更调查数据,研究揭示了全省近八年来建设用地利用结构信息熵的时空变化,并在此基础上进一步探讨了土地利用结构动态变化的驱动机制。结果表明:自1997年以来,甘肃省建设用地利用结构信息熵呈上升趋势,即建设用地多样性程度提高,用地结构趋于均衡;通过驱动力分析发现造成建设用地结构演变的主要驱动力是人口增长和城镇化水平,而各经济发展指标次之。

| Abstract: | According to statistical and datailed survey date of constructive land use from 1997 to 2004,the special-temporal changes of constructive land-use structure in Gansu Province during the last 8 years were analyzed.Based on which the driving forces of information entropy were discussed in this article.The results showed: the information entropy of the constructive land use structure in Gansu has been rising in general since 1997,in other words,the multiple of constructive land has been rising,land use structure tends to equilibrium.The driving forces were analyed,and the following conclusions were reached: population growth and urbanization are the most closely related to the information entropy of constructive land use structure,then followed by other economic factors. |
