摘　　要：运用极差、标准差、变异系数、基尼系数、综合扩展系数、泰尔指数等分析了陇海—兰新—北疆沿线城市建设用地时空差异,以期在新一轮土地利用规划中为不同城市建设用地供给方向的确定奠定科学基础。结果表明:①在时间上,1991—2009年陇海—兰新—北疆沿线城市建设用地绝对和相对差异均呈扩大趋势;除仓储用地外,其它类型建设用地相对差异呈上下波动或小幅下降趋势;建设用地综合扩展极化现象明显,且整体上城市综合扩展系数陇海沿线城市大于兰新—北疆沿线城市。②在空间上,2009年陇海—兰新—北疆沿线50%以上城市人均建设用地超出国家Ⅳ级标准上限,尤其是中等城市和小城市;各类城市建设用地区域分布的差异度不同;城市建设用地扩张与其经济效益之间并无直接的关联关系。Using range, standard deviation, coefficient of variation, Gini coefficient, integrated expansion coefficient of urban construction land, Theil index and so on, this paper has analyzed spatial-temporal differences of urban construction land along Longhai-Lanxin-Beijiang railway so as to provide the scientific foundation for urban construction land planning of different cities. Tile results show that： （1） From 1991 to 2009, both the absolute difference and relative difference among different cities had a growing trend. Apart from land for storage, relative differences of the other types of urban construction lands had either fluctuation tend or fluctuation descending trend; Polarization phenomena of urban construction land integrated expansion is significant, and in general, the integrated expansion coefficient along Longhai railway was bigger than that along Lanxin-Beijiang railway. （2）In 2009, urban construction land per capita in more than half of the cities along Longhai-Lanxin-Beijiang railway outnumbers the national standard IV level; The areal distribution difference degree of different urban construction lands was different, also, there was no direct matching relation between urban construction land expansion and its economic benefit.
