摘　　要：[目的]探究云南高原盆地城市水源地土地利用空间结构,为该区城市水源地土地利用结构调整提供依据。[方法]以洛伦兹曲线和分形方法相结合,对云南省9个典型高原盆地城市水源地土地利用空间结构进行了分析。[结果]9个典型高原盆地城市水源地土地利用类型中建设用地、草地和未利用地当前分布欠缺合理性,很不均衡,而未利用地和水域的空间结构镶嵌程度复杂,稳定性差。[结论]各个水源地现存的土地利用空间结构缺乏从水源保护角度出发的统一规划,土地利用问题突出。[Objective] The spatial structural of use types of water source lands in basin area of Yunnan Plateau was analyzed to provide bases for the transformation of land use types. [Methods] Lorentz curve and fractal method were used to analyze the spatial structural of urban water-source land use in basin area of Yunnan Plateau.[Results] The results showed that, currently, the water-source land use in basin area of Yunnan Plateau with respect to construction land, grass land and unutilized land was uneven and unreasonable. Moreover, the unutilized lands mosaicked messily with aquatorium and they were unstable. [Conclusion] The current land-use in basin area lacked a well-designed plan and an elaborative scheme regarding with water source protection should be conducted.
