As a major group of macroinvertebrate benthos, aquatic insects can reflect the status of river ecosystem to a great extent, and are one of the important biological monitoring indicators. Sediment and flow velocity are very important environmental factors which can affect community structure and biological characteristics of aquatic insects in rivers. However, there were few studies on the relationship between benthos and the two factors at home and abroad. In future, it is suggested to use physical model to simulate and construct the coupling relationship between diversity index of aquatic insects, flow velocity and sediment, and can reveal the selection mechanism of aquatic insects on velocity and sediment, so as to provide scientific basis for the protection and restoration of aquatic habitat of small rivers in mountainous areas.
