摘要： 基于西峰区1997—2012年土地利用变更数据，对西峰区土地利用空间结构及其动态变化特征进行定量分析。通过SPSS对16年土地利用现状数据进行分析处理，采用经济学中的空间洛伦茨曲线和基尼系数，绘制洛伦兹曲线，分析西峰区土地利用结构特征。结果表明，西峰区土地利用结构分布比较均匀。从空间尺度上看，土地利用类型中水利交通用地和其他建设用地这2种地类分布最不均匀。从时间尺度上看，耕地、林地、城乡建设用地、其他建设用地和未利用地分布离散程度增大，分布趋向分散，而园地、牧草地、其他农用地和水利交通用地分布趋向均衡。

Abstract: Spatial structure of the land use and its dynamic in Xifeng District, Qingyang, Gansu Province was quantitatively analyzed based on the land use changing data from 1997 to 2012. The characteristic of spatial land use structure of Xifeng District was analyzed with Lorenz curve and the Gini coefficient based on the land use data with SPSS. The results showed that the land use structure of Xifeng District was more evenly distributed. From the perspective of spatial scales, the spatial distribution of irrigation and transportation land and other construction land were the most uneven. From the perspective of time scale, farmland, forest land, urban and rural construction land, other construction land and unused land were scattered distributed, while, garden, grassland, other agricultural land, irrigation and transportation land were more evenly distributed.
