新疆土地利用空间结构和布局分析

Analysis on the Spatial Structure and Distribution of Land Use in Xinjiang

基于2008年新疆土地利用数据,采用计量地理学模型,并借助SPSS软件和ArcGIS软件,对新疆各地州(市)的土地利用数量结构和空间格局现状进行了定量分析,并与全国土地利用结构对比。结果表明:新疆现状土地资源具有明显的地域差异,北疆地区土地利用程度明显优于南疆,这种差异与所处的地理位置、地形地貌密切相关;土地利用结构的多样性和集中度由北向南递减;新疆的土地利用结构单一,各地区的土地利用类型组合系数普遍不高,反映出新疆土地利用的整体功能还有很大的提升空间。

Based on data of land use in Xinjiang in 2008 ,by using quantitative geography model ,SPSS and ArcGIS software ,a quantitative analysis of land use structure and spatial pattern in Xinjiang has been carried out ,and compared with the national land use structure .It is showed that land resources of Xinjiang at present have obvious geographical differences ,land use degree of northern region is obviously better than the south .The difference is closely related with geographical location and the landform .Diversity and concentration of land use decreases from north to south .Land use structure in Xinjiang is very simple ,land use combination coefficients are generally not high in different regions .It reflects that the overall function of land use in Xinjiang still has much space for im‐provement .
