中文摘要	River networks evolved in different ways depending on the environmental and geological conditions, leading to various river network patterns. The relationship between the river patterns and the environmental conditions was analyzed by classifying three typical river network patterns (feather, leave, and branch) based on their planar topological features in satellite images. Statistics are given for the Horton ratios and basin shape parameters for the three patterns. The bifurcation ratios converge to 2, the length ratios to 4, and the area ratios to 4 for large river networks, regardless of the environmental conditions. However, the Horton ratios differed greatly at small scale suggesting that the Horton ratios can be used to reflect the influence of environmental conditions at small scales.
