摘要
Debris flow is an important earth surface process to the geologic environment evolution in Moxi River Basin. Investigation of the formation and evolution of the debris flow stream can provide useful basic data for the research of geologic environment evolution in Moxi River Basin since the Quaternary. Based on the topographical statistic data of 51 debris flow gullies, the distribution of debris flows in Moxi River Basin shows an asymmetric character obviously. There are fractal phenomenon and self-similarity among the debris flow numbers and the channel length, channel gradient and catchments area. Finally, this paper discusses the debris flow nonlinear evolution character and its response to the environment.
