Technical Field
The invention relates to the technical field of ecological management engineering, in particular to a system and a method for repairing an anti-scouring hydro-fluctuation belt.
Background
The hydro-fluctuation belt is a dry-wet alternate mixed zone formed by connecting land and water in water bodies such as rivers, lakes, reservoirs and the like and periodically submerged along seasonal and tidal fluctuation, and plays a vital role in water body health and ecological safety as an ecological barrier of the water body and along the bank of the water body.
Compared with water bodies such as lakes, reservoirs and the like, the hydro-fluctuation belt of the inland river has the problems that the water flow speed is higher, the hydro-fluctuation belt is more frequent along with the river water, and the hydro-fluctuation belt is more seriously washed by the water bodies. Once the protection is not good, the falling zone is easy to be damaged, so that the inland river water body directly erodes the bank, the water resource is polluted, and the soil quality on the bank is reduced.
When the hydro-fluctuation belt is damaged, the conventional treatment method adopts hard materials such as masonry, concrete and the like to cast the breakwater, but the method causes the natural environment in the water body to be damaged and is not beneficial to the ecological safety in the river channel. The existing method for treating the side slope by a greening method is also available, but the water flow speed in the inland river is high, so that conventional greening vegetation and soil are easily taken away by running water, and the anti-scouring capability is insufficient, so that the treatment effect is poor; in addition, the water level caused by tidal change changes frequently, the river bank is washed frequently, the same effect cannot be achieved in water bodies such as lakes and reservoirs, construction and transformation are carried out on the bank for a long time, and the problems of high cost and high cost exist when a method of intercepting one section of river channel to control one section of river channel is adopted.
