摘　　要：该文从相对强度和绝对强度2个视角构建土地利用/土地覆被(LUCC)变化强度系数分析框架,结合用地扩张分析策略(LEAS),剖析高山峡谷地区土地利用变化特异性驱动机理.结果表明:(1)土地利用具有明显的变化趋势,未利用地转草地、草地转林地、耕地转林地、耕地转水域及水利设施分别具有系统、绝对、相对、相对倾向性特征,转移数量的多少与其对区域土地利用结构的影响程度没有相关性.(2)驱动因素具有差异化,高程(DEM)平均贡献度达0.196,垂直地带性决定发生转移的主要方向,道路是城市发展的重要影响因素.最后,针对高山峡谷区域特异性提出合理建议,以期为土地资源合理配置和可持续发展提供参考.This study constructs an analytical framework for land use/land cover(LUCC)change intensity coefficients from the perspectives of relative and absolute intensity.By integrating the land expansion analysis strategy(LEAS),it investigates the unique driving mechanisms behind land use changes in alpine canyon regions.The results are as follows.(1)Land use exhibits distinct transformation trends.Unused land transitioning to grassland,grassland to forestland,cropland to forestland,and cropland to water bodies and water conservancy facilities show systematic,absolute,relative,and relative tendencies,respectively.The amount of land transferred does not correlate with its impact on regional land use structure.(2)Different driving factors have been identified.Elevation(DEM)has an average contribution of 0.196,with vertical zonation determining the primary direction of land use transitions.Roads play a crucial role as an influencing factor in urban development.Finally,targeted recommendations are proposed based on the unique characteristics of alpine canyon regions to provide a reference for the rational allocation of land resources and sustainable development.
