Method for recovering underwater ecosystem of a river

Abstract

A river ecosystem restoration method, including the following stages: the first stage of maintaining the same height between the upstream partition wall and the river bottom in order to make the end face of the river bottom and the upstream partition wall on the same line; The second stage of maintaining the same height between the downstream partition wall and the river bottom in order to make the end face of the river bottom and the downstream partition wall on the same line; between the aforementioned upstream partition wall and the downstream partition wall according to the planned water depth of the river The third stage of the water storage area is to build a certain depth, and then form a water storage area that can release various aquatic organisms that meet the local characteristics. The first to third stages have formed multiple swamp areas; The fourth stage of the rapids zone of action. The present invention can not only restore and maintain the ecological system in the river water, but also prevent river pollution by improving the natural purification ability of the river, thereby making the related natural ecological system of the river ecological system healthier and making it easier to use the hydrophilic space environment.

Description

technical field [0001] The invention relates to a construction method for restoring the ecological system in river water. The invention forms a plurality of upstream and downstream partition walls maintaining the same height as the river bottom, constructs a water storage area with a certain depth between the upstream and downstream partition walls, and then forms A plurality of swamp areas; rapids are formed between these swamp areas to create a basic environment that promotes the restoration of the aquatic ecosystem, and then the river's aquatic ecosystem is restored through the aforementioned basic environment. Background technique [0002] The current water control method is mainly a technology developed to ensure the water resources we need, and it includes various structures such as multi-purpose dams, simple concrete dams belonging to small and medium-sized dams, and rubber dams to cross the river. [0003] By crossing the river, the above structure ensures water reso...

Problems solved by technology

However, the various fishes that are driven by instinct to move towards the best living environment are also unable to move freely due to the interruption of water flow, which in turn forces the fishes to engage in inbreeding, which significantly reduces the variety and number of fishes that feed on these fishes The number of animals is also reduced due to the destruction of the food chain, which eventually leads to an imbalance in the ecosystem

[0004] The isolation and destruction of the ecosystem has brought many environmental problems, especially the dams have blocked the movement of fish and caused great damage to the ecosystem of aquatic organisms
