摘要
Helong City is located in the northeast of Changbaishan Mountain range with a bad geologic environment,where debris flow,collapse and landslide always break out.According to the survey data of 34 debris flows gully in Dongcheng District of Helong City,with fractal theory,the writer did systematic research on fractal feature of debris flow gully and its change features of fractal dimensions in different observation scales.The nonlinear relationship may reveal the nonuniformity and self-similarity of debris flow gully evolution.
