Taking the upper reaches of the Yangtze River at Guangyang Dam as an example, a physical model was constructed to analyze the changes of water depth and flow field in the corresponding river section before and after the implementation of the continuous pool-riffle type natural habitat restoration technology scheme. And then the effects of the habitat restoration scheme on fish spawning grounds, habitats, overwintering activities and waterways were discussed. The study show that after the implementation of the habitat restoration scheme, the area of the slow flow area in the test reach increased significantly, and a local slow flow was formed between the group of spur-dike, which was conducive to fish spawning and habitat; The implementation of the scheme did not adversely affect the vessel traffic in the channel of the river.
