To analyze the potential influence of the construction and operation of the cascade junction on the hydrologic regime of four major Chinese carps spawning sites in the downstream of the Xinjiang River, 21 parameters were selected to establish the hydrological index system of fish spawning sites. The one-dimensional hydrodynamic model was adopted to analyze the hydrological regime of Daxidu spawning site before and after the construction of the cascade junction. The range of variability approach was used to analyze the hydrological changes of spawning grounds during the breeding period before and after the construction of cascade junction. The results show that the flow during the breeding period decreases after the operation of the cascading junction, which made the variation range of water flow limited in a small range. Furthermore, the number of high flow pulse decreased, which reduced the stimulation signal to spawning of four large fishes. This study quantified the impact of the construction of cascade junction in the downstream of the Xinjiang River on the spawning grounds during the breeding period, and provided scientific guidance for the design of the local hub operation scheme.
