摘　　要：以三峡库区长寿段2009年土地利用现状图和2012年土地利用变更图为依据,采用计量地理模型和ArcGIS软件空间分析技术,从土地利用现状和动态变化两个方面分析了土地利用空间结构的特征和规律.研究结果表明长寿区土地利用多样化程度较高、土地利用空间结构差异显著、土地利用组合类型多样,各个乡镇土地利用类型区位意义不同;随着社会和经济的发展,全区土地利用结构转变较快,各个乡镇土地利用变化差异显著;全区土地利用信息熵增大,土地利用结构整体呈无序化,应该加大土地利用的调整力度.Based on quantitative geographic models and GIS software ,land use map of Changshou district in Three Gorges Region in 2009 and its amendatory map in 2012 have been used to analyze the land use in term of spatial structures and their dynamic characteristics .The results indicate that land use in Chang-shou District took on the comparatively high diversity indexes ,significantly different spatial structures and various types ,and the location significance of land use type was quite different in each town .With the de-velopment of local society and economy ,the land use structures have been changed swiftly and the changed degree of land use types in each town is quite different .The information entropy of land use increases gen-erally and the overall structures of land use are disordered according to the information entropy .So the ad-justment of land use should be strengthened .
