The river ecological restoration is to restore the biological population and the structure of the damaged water ecological system by various methods by utilizing the ecological system principle, reconstruct a healthy aquatic ecological system, restore and strengthen the main functions of the water ecological system and realize the virtuous circle of overall coordination, self-maintenance and self-succession of the ecological system. Protection and restoration of the river system to a more natural state and to take advantage of sustainable features to increase the value and biodiversity of its ecosystem. Namely, the process of repairing the physical, biological or ecological state of the damaged river, so that the repaired river is healthier and more stable than the river before repair. The objectives include: the riverbank zone is stable, the water quality is improved, the habitat is increased, the biodiversity is increased, the fishery is developed, and the aesthetics and entertainment are realized, so that the river can be more natural. Impact evaluation and monitoring included: the ecological monitoring and the caused influence tracking evaluation of the restoration process and the restoration, and the prediction evaluation of the model are utilized, and whether the success or not directly influences the production, the life and the health of human beings. The effectiveness of the remediation can be characterized by monitoring populations and numbers of aquatic macroinvertebrates, fish and wading birds, and wetland habitat improvement, which when the system is self-sustaining means that remediation is complete. The task of river water system ecological restoration is 4 items: firstly, the water quality is improved; secondly, the hydrological situation is improved; thirdly, repairing the river landform landscape; fourthly, the maintenance and recovery of the diversity of the biological communities. The general objective is to improve the structure, function and process of the river ecosystem towards naturalization. The improvement of water quality conditions is the premise of river ecological restoration. By means of standard discharge and total amount control, clean production and development of circular economy are advocated to improve river water quality. Aims to improve the water quality standard-reaching rate of a water functional area in a planning area, control the total amount of river-entering pollutants, approve pollutant-receiving capacity and control eutrophication of lakes and reservoirs. Controlling Toxic Organic Chemicals (TOC) and heavy metal pollution. The improvement of the hydrological situation not only ensures the ecological basic flow, but also considers the flow process recovery of the natural water flow so as to meet the requirements of biological target life history. As mentioned above, the hydrologic situation can be described by 5 elements, namely flow, frequency, duration, timing of occurrence and rate of change. Stress factors that need to be eliminated and alleviated include: the runoff of the downstream river section is greatly reduced, even dried and cut off due to excessive water intake; the runoff process is homogenized due to the runoff regulation of the reservoir; the flood pulse effect is weakened; change of flood occurrence time; significant changes in flood duration, etc. Eliminate or slow down these stress factors and improve the hydrologic situation of rivers. The repair measures include: the ecological water is ensured through reasonable allocation of water resources; improving a gate dam scheduling scheme; taking measures such as reservoir dispatching and the like into consideration for ecological protection. Stress factors that need to be eliminated and alleviated include: ecological barrier effect caused by dam; river canalization and linearization; encroaching on the flood bank; ecological barrier function of the dike; waterproof hard slope protection and bank protection engineering; making a field around a lake; disordered sand mining and the like. The river landform restoration comprises the following steps: repairing the longitudinal continuity of the river; repairing the lateral connectivity of the river and the connectivity of a river, a lake and a water network; river morphology restoration includes serpentine nature of planar morphology, diversity of cross-sectional geometries, and restoration of water and porous properties of slope protection materials. In the prior art, in order to repair a river channel, the most common method is to add a repair liquid into the river channel, but the repair liquid is difficult to enter the lower bottom of the river after being put from the surface because the river channel is flowing, so that the condition of incomplete repair is easy to occur; meanwhile, besides the repair liquid, a biological film hanging mode is adopted, but the fixation in a river is difficult; and requires a separate device for containment. Therefore, further improvements are awaited.
