Due to the unique climate characteristics such as arid and concentrated rainfall, gully erosion is very serious in the arid river valley of the Jinsha River. Based on morphological characteristics of gully heads, this paper applied fractal geometrical theory to analyze fractal curvature and fractal dimension of soil particle-size distribution of the gullies investigated, and discovered the correlation between gullies' morphology and development under different land-use patterns. As a result, it could indicate that the difference of natural environmental characteristics reflected by changes of gully morphology and provide a new way for studying spatial structure and monitoring dynamic growth of gullies. In additional, the paper has an important theoretical guiding meaning for controlling gully erosion and preventing land degradation.
