For example, two ways of replenishing and draining water can be adopted for high-quality surface water. One is natural water seepage and drainage under no pressure, and at the moment, the water pump is not started. When water is naturally replenished, the downstream gate valve of the water replenishing and draining pipeline 1 is closed, and the upstream gate valve of the water replenishing and draining pipeline 1 is opened; when water is drained naturally, the upstream gate valve of the water supply and drainage pipeline 1 is closed, and the downstream gate valve of the water supply and drainage pipeline 1 is opened.

This enables high-quality surface water in the ecological river to rapidly permeate into the ground through the water replenishing and draining pipes 1.

It should be noted that the ecological river is suitable for plain areas with water shortage and also suitable for medium and small rivers.

The ecological river channel has the following advantages: first, the inferior surface water in the ecological river course can be effectively prevented from polluting soil and groundwater through the concrete bottom 3 and the concrete slope 4. Secondly, groundwater can be replenished as required, and the groundwater level can also be lowered as required, so that the groundwater level is within the optimal range. Thirdly, water resource saving is facilitated. Because the ecological river channel does not seep water, the water control building 8 can realize the function of stopping up water when the water level in the ecological river channel is low so as to maintain the optimal water level of the ecological river channel, reduce water supplement to the ecological river channel and save water resources well. Fourthly, the ecological direction is good and the service life is long. Because the ecological river channel can be choked or drained, the water depth, the water level and the width of the ecological river channel are stable for a long time, the ecological river channel is beneficial to the growth and the breeding of aquatic plants, reeds, aquatic insects, algae and fishes, and is beneficial to forming bird and insect habitats, and further forming a thick food chain and a thick biological chain. Meanwhile, the aquatic plants, the reeds, the aquatic insects and the algae can purify water quality, absorb raise dust and sand dust and adjust air humidity. Fifthly, the ecological river channel can block water, is beneficial to diversion and irrigation, and reduces the water use cost. Sixthly, the ecological river channel is kept to have a proper water level, so that navigation is facilitated, flood control is safe, investment increase is less, and function promotion is large.

In the embodiment of the application, the poor-quality surface water refers to the condition that the surface water quality exceeds the standard and does not have permeation to the underground, so that the underground water is well protected. It should be noted that poor surface water means poor water quality and does not meet the requirement of discharging to underground water. And the high-quality surface water meets the requirement of discharging to underground water. And abundant high-quality surface water in the ecological riverway seeps downwards to supplement underground water. Meanwhile, underground water can be pumped to adjust the underground water level when the underground water level is too high, so that the soil is prevented from being salinized. Moreover, the ecological river channel has strong water purification capacity, thick food chains and biological chains, long-term stability of water level and water depth, flood control safety and capability of being artificially controlled.

In a specific embodiment, soil 7 is placed in a square surrounded by the transverse grid plates 5 and the longitudinal grid plates 6 of the ecological river channel, and flowers and plants are planted in the square. For example, the high-stem deep-root aquatic plants such as reeds are planted in the range from 0.3 m above the waterline to 1.5 m below the waterline to provide food for fishes and shrimps, which are habitats of birds and insects, and can purify water quality, and meanwhile, the high-stem deep-root aquatic plants are not easily washed away by water, and can better protect the concrete slope protection 4. Flowers and plants are planted on the part of the concrete revetment 4 above the water surface.

Further, one control room 9 is provided at each proper distance, and the distance between the control rooms 9 is determined by factors such as ground water and surface water, for example, 10 km, 5 km, 1 km, and the like. The control chamber 9 is used for supplying water to the underground when the surface water is more and has high quality and the underground water level is low; and when the underground water level is high, the water is drained into the ecological river channel so as to prevent the soil from being salinized.

Meanwhile, a water control building 8 is arranged at each proper distance to improve the water depth of the ecological river channel and stabilize the water level, and the distance is determined by factors such as terrain gradient, application and the like, such as 50 kilometers, 100 kilometers, 150 kilometers and the like. The water control building 8 has the function of damming up water when the surface water is low, keeping the ecological river channel to have enough water depth and water level and maintaining the ecology of the ecological river channel. When the surface water is large and high in quality, the water level is high, and water is rapidly seeped into the ground. However, when the surface water quality is extremely poor, the ecological river cannot be relied on for natural purification, and water is drained through opening the gate. And when flood occurs, the water is drained under the opening of the gate. In addition, the ecological river channel backwater increases the self-flowing water diversion range and reduces the water use cost.

It is to be understood that the above embodiments are merely exemplary embodiments that have been employed to illustrate the principles of the present invention, and that the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
