Abstract: There are many small-scale mountain rivers in Xiangshan Bay Basin, which flow from low mountains to the sea and form a relatively independent small watershed. In this study, the small-scale river features in the inner bay were quantitatively analyzed by the combined method of fluvial landform mathematical model and geographic information system technology. The results show that: (1)Dasong River is the longest and the most meandering river in Xiangshan Bay Basin, whose river fractal dimension value is generally small. (2)The river structures of Fuxi Stream and Dasong River are more complicated and well-developed than those of other rivers in Xiangshan Bay Basin. (3) Overall, apart from the some rivers (such as Yangong River and Qiancang River), other rivers show a trend of concave and stair-step shape. (4)The applications of S-A model has a certainty limitation. Fuxi Stream and Dasong River's bedrock riverbeds are in equilibrium in the S-A model.
