The Fractal Characteristics of the River Network in the Landslides Area

摘要

This paper applies box-counting model to study the fractal characteristics of 17 sub-watersheds 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 and that fractal dimension values of sub-watersheds near the Yangtze River are generally smaller than those of small watersheds far away from the Yangtze River. It shows that the fractal of water system in the study area has obvious spatial differentiation. The relationship between the fractal dimension of topography and landform and the development of landslide is closely related to the erosion of the river. 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.
