洛伦兹曲线在新疆生产建设兵团土地利用结构分析中的应用

基于新疆生产建设兵团1999～2009年土地利用现状数据,应用经济学中衡量财产、资源分配程度的洛伦茨曲线与基尼系数方法进行新疆生产建设兵团土地利用结构的定量化研究。结果表明:新疆生产建设兵团的在各用地类型中城镇村及工矿用地、交通运输用地分布较为均衡,空间基尼系数分别为0.064、0.183;园地分布较为集中,空间基尼系数为0.485。过去10年间,林地、城镇村及工矿用地以及交通运输用地分布趋向均衡,其余地类分布趋向集中,其中园地变化最大。空间洛伦茨曲线理论可直观地反映区域土地利用类型在地域上的配置及其对比关系,基尼系数可对集中情况进行定量化研究,为新疆生产建设兵团土地利用结构优化提供参考。

Using Lorenz Curve to Analyze Land Use Structure in Xinjiang Production and Construction Corps

Based on land use data from 1996 to 2009 in Xinjiang Production and Construction Corps,the quantitative analysis of land use structure was conducted by using Lorenz curve and Gini coefficients which were applied to measure property,the extent of the resource allocation.The results indicated that town village and industrial land and the transportation land distribution is more balanced,the spatial gene coefficient are 0.064,0183 respectively;garden distribution is the most concentrated with the gene coefficient 0.485.The last 10a,forest land,town village and industrial land,transportation land use distribution trend is balanced,the rest of class distribution tend to concentrate.Among them,the garden change is the most significant.Space Lorentz curve theory can reflect the regional land use types in the region configuration and contrast relations,concentration quantitative research by using Gini coefficient can provide a reference for land use structure optimization of Xinjiang Production and Construction Corps.
