Abstract: Take the Guangyang Dam section of the upper reaches of the Yangtze River as an example to build a physical model of continuous pool-riffle fish habitat to simulate the natural fish habitat. By analyzing the changes of water depth and flow field in the corresponding river reach before and after the implementation of the model scheme, the influence of habitat construction scheme on fish spawning field, habitat, overwintering activities and waterway is discussed. It is found that after the implementation of the scheme, the area of the slow flow area of the test area increases greatly, and the local slow flow is formed between the spur-dike group, which is conducive to fish spawning and habitat of the fish, the fish habitat construction scheme is proposed.
