In order to explore the calculation method of water demand of water-reduced river landscape under hydropower development, combined with the data of hydrology and social economy in the region, this paper compared the changes of landscape characteristics after water reduction in similar projects. Taking the water reduction channel caused by Danba Hydropower Station as an example, the landscape evaluation factors were chosen comprehensively. Considering human visual effects, the landscape water demand evaluation system was established. A calculation method for the landscape water demand of the water-reduced reaches caused by the construction of hydropower stations was proposed. Based on the hydraulic model, the landscape indicators of each river section were calculated according to the determined index system, and the water volume required for the wide valley section, canyon section and county river section to meet the landscape requirements of water-reduced river channels is 70.4 m3/s, 64.8 m3/s, 50.7 m3/s. The 70.4 m3/s is taken as the landscape water demand of the whole reach of the reduced water.
