【摘要】 利用信息熵、洛伦茨曲线、基尼系数、数据包络分析(DEA)等方法,以甘肃省14个地州市为研究对象,从土地利用结构和效率等方面评价了14个地州市的土地利用结构状况。结果表明:信息熵最明显的是兰州市,其均衡度与信息熵同步,但优势度不明显;最低值为陇南市,优势度显著,优势集中在居住用地、公共管理与公共服务用地、道路交通设施用地、公共设施用地等用地方面。城市土地利用结构的有序度存在着显著的空间差异,庆阳、酒泉、陇南三市DEA有效,土地利用效率较好;天水市DEA无效,土地利用效率相对较低。更多还原

【Abstract】 Using the methods of information entropy, Lorentz curve, Gini coefficient and data envelopment analysis(DEA), this paper evaluates the land use structure of 14 prefectures in Gansu Province from the aspects of land use structure and efficiency. The results show that the most obvious information entropy is Lanzhou City, whose equilibrium and information entropy are synchronized, but the dominance is not obvious; the lowest value is Longnan City, the dominance is significant, and the dominance is concentrated in residential land, public management and public service land, road traffic facilities land, public facilities land and other land. There are significant spatial differences in the orderliness of urban land use structure. The DEA in Qingyang, Jiuquan and Longnan is effective and the land use efficiency is better; the DEA in Tianshui is ineffective and the land use efficiency is relatively low.更多还原
