[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.
