基于GIS流域地貌形态特征分形与计算方法研究

Research on Fractal Dimension and Its Calculation Method of Watershed Topographic Characteristics Based on GIS

    摘要
  • 摘要: 提出了基于GIS平台流域地貌特征分形信息维数的计算模型;探讨了地貌分形信息维数的计算方法,并采用Avenue语言开发了基于Arcview环境下流域地貌特征分形信息维数计算软件,并对长江流域弹子溪小流域地貌分形信息维数和数据无标度区进行了计算和深入分析。

     

    Abstract: In this paper,the theory which characterizes the topographic characterics of large watershed using fractal information dimension(FID) is firstly discussed,and the FID mathematic model for the large region based on GIS software platform is provided and established.Accordingly,the FID calculation method is discussed,and then the software to calculate FID values using avenue language based on Arcview system is programmed.
