摘要
以陕西省汉阴县为例,运用分形理论计算不同地貌类型下土地利用类型图斑的分维数和稳定性指数,结果表明:该县的土地利用结构具有明显的分形特征,通过对比不同地貌类型上不同土地利用类型的分维数和稳定性指数,得出在不同地貌类型上各种土地利用类型的分布复杂状况,为进一步改善当地的土地利用结构提供一定的科学依据与参考。
Taking Hanyin county in Shaanxi as an example,the fractal dimension and stability index of different land utilization types of patches under different geomorphic types were calculated by using fractal theory.The results showed that the land utilization structure of this county had obvious fractal characteristic.The paper studied the complex distribution status of different land utilization types under different geomorphic types by comparing the fractal dimension and stability index of different land utilization types,and the results could provide scientific references for improving the local land utilization structure.
