The Fractal Characteristics of the River Network Based on Horton Law in the Landslides Area

Abstract

This paper applies Horton law to study the fractal characteristics of 17 subwatersheds in the study area from Badong county to Zigui county in TGP reservoir region. The results indicate that the small watersheds have obvious fractal characteristics. There is a clear correlation between the fractal dimension of river network and spatial distribution of landslide and that the area with large fractal dimension is conducive to the formation and development of landslides. The results show that the fractal model provides powerful tools for quantitative description of the river network and the relationship between the river network and the landslides.
