Application of P-A Fractal Model in the River Network of the Landslides Area

This paper applies P-A 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 the fractal of water system in the study area has obvious spatial differentiation. The D-AP fractal dimension is usually higher in the places where the erosion of the landscape is more serious and there is more landslides relatively. 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 P-A fractal model provides powerful tools for quantitative description of the river network and the relationship between the river network and the landslides.
