| Abstract: | Helong City is located in the northeastern Changbai Mountain with a poor geological environment, there often occur debris flows, collapses and landslides; especially debris flows restrict the local economic development. Based on fractal theory and the surveying data of 34 debris flows, the authors studied fractal feature of debris flow gully and its various situations of fractal dimensions in different observation scales. The nonlinear relation reveals the development of non-uniformity and self similarity of debris flow gully. |
