Abstract: Based on the researches on fluvial geomorphology classification, the index system of river classification was proposed with four indices: stream order, confinement degree, channel number and sinuosity. And a fast river classification framework was established with the selected indices. Liaohe River basin was selected as an example to apply the framework at reach level. A total of 3158 reaches in Liaohe River basin were divided into 20 river types. The results showed that the classification framework has the advantages that indices are easily calculated, and the framework is suitable for basin management strategy establishment for large area basin. Management strategy was raised based on the structure, function, process and habitat type for all river types. Three river types with high stream order and high sinuosity and 2 river types with multiple channels should have the highest priority for conservation in Liaohe River basin. For the three river types in the source region, soil erosion should be concerned and the disturbance on river channel should be reduced. For the three tributary river types in the plain area, the farmland reclamation and the discharges of sewages should be reduced.
