Abstract: With the improvement of human cognitive ability, the improvement of river ecological environment has received more and more attention. Ecological replenishment is of great significance to improving river ecological environment. On the basis of qualitatively analyzing the water environment problems along the Qiputang River, the water balance method combining water exchange rate are used to calculate the ecological water demand. The results show that Shaxi Town has the largest water demand, followed by Zhitang Town and Bacheng Town. The determined key areas of ecological water replenishment along Qiputang River and ecological water demand of each region can provide a basis for ecological regulation. Ecological water demand along the Qiputang River can be partly satisfied by water ecological dispatch, and water environmental problems in the key areas can be improved by increasing the water exchange times.
