In the process of river regulation, there is a lack of awareness of water ecological governance. "Water saving priority, spatial balance, systematic governance and two hands" is the idea of water control in the new era. At this stage, we must actively respond to the call in the process of river regulation. However, in the process of traditional river regulation, some areas pay too much attention to the reconstruction of the river and neglect the importance of river water ecological environment protection.
Pollutants entering the river lead to the destruction of the ecological function of the river. There are still some pollution sources in the river that have not been intercepted and blocked, and there is also the phenomenon of seepage at the rainwater and sewage outlets. Over time, the ecological function of the river is seriously damaged, which reduces the ecological regulation function of the river water and the self recovery ability of the river water. In addition, residents around the river discharge domestic garbage and production and domestic wastewater into the river, resulting in the decline of river water quality.
