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.
