甘肃省土地消耗指数时空差异分析

摘要

Took 14 cities and prefectures in Gansu Province as the basic unit,based on the construction land and GDP, using land consumption index and coefficient of variation,the land consumption index of cities and prefectures in Gansu Province from 2006 to 2013 were analyzed.The results showed that: Land consumption of cities and prefectures in Gansu Province overall decreased gradually dropped from 500.32 hm2/ten thousand yuan in 2006 to 152.16 hm2/ten thousand yuan in 2013,decreased 69.59%.The degree of economical and intensive land use continuously improved.Land consumption of each citie or prefectures was gradually narrowing difference.The degree of difference decreased from 0.96 in 2006 to 0.48 in 2013.%以甘肃省14个市(州)为基本单元,采用土地消耗指数和变差系数,将建设用地和GDP结合,对甘肃省及各市(州)土地消耗指数时空差异进行分析.结果表明:甘肃省及各市(州)土地消耗指数总体呈逐渐下降趋势,甘肃省土地消耗指数由2006年的500.32 hm2/万元下降为2013年的152.16 hm2/万元,降低了69.59%,表明土地利用节约集约程度在不断提高;各市(州)土地消耗指数差异性在逐渐缩小,差异程度由2006年的0.96下降到2013年的0.48.
