| 摘 要： | 基于安化县各乡镇1998和2008年土地利用现状数据,应用经济学洛伦茨曲线和基尼系数定量化研究某土地利用结构。结果表明,安化县各乡镇5种主要用地类型的空间分布及其时间变化均具有不均衡性。在空间尺度上,未利用地和耕地分布最不均衡,居民点及工矿用地和园地次之,林地分布相对均衡;在时间尺度上,耕地、林地、居民点及工矿用地的不均衡程度有所减弱,而园地、未利用地却有增加。

| Abstract: | Based on the land use data of each township in Anhua County,quantitative study was carried out for land use structure by using Lorenz curves and Gini coefficients(GC).The results indicated that in Anhua,the distribution of five major land use types was temporally and spatially unbalanced.In spatial scales,the most unbalanced lands were unused lands and cultivated lands,followed by those used for constructions and the garden.The forestry lands were balanced.In time scale,the unbalanced degree of the cultivated lands,forestry lands and those used for constructions decreased,while that of the garden and unused lands increased. |
