Process of flexible type stone cage method for building watercourse ecological system

Abstract

The invention discloses a process of a flexible type stone cage method for building a watercourse ecological system. The process comprises the following steps that cofferdams are built through flexible type stone cages to form an ecological restoration area, the water surface between the cofferdams is provided with a floating floor, and the side, far away from the coast, of the floating floor is provided with a mycoderm hanging curtain; submerged plant pioneer species strong in pollution resistibility are planted in the ecological restoration area, and primary restoration is conducted; a plurality of kinds of submerged plant expansion species are planted in the ecological restoration area; invasive species are eliminated at regular intervals. According to the technical scheme, by means of the process, the water ecological system can be rapidly built in a watercourse where the flowing speed is high, the water depth is high and tide fall is large; as the flexible type stone cages and bagged stone are adopted, and after the ecological system is restored, the stone cages and stone bags can be conveniently recycled and reused. Meanwhile, the process has the advantages of being low in cost and beneficial to being popularized widely.

Description

technical field [0001] The invention relates to a process for constructing a river ecosystem by a soft gabion method, and belongs to the field of river water environment management and ecological restoration. Background technique [0002] The river ecosystem is an important part of the natural ecosystem, and it is of great significance to maintain the diversity of the ecosystem. However, with the continuous acceleration of the urbanization process, human beings continue to invade the natural ecological field, causing huge damage to many original ecological systems. For example, in many places, the waterfront of the river is built into a hard revetment, which has caused huge damage to the original water ecosystem, significantly reduced biodiversity, and caused a decline in water quality, and the landscape value of the river bank has also been greatly affected. [0003] For this reason, people have spent a lot of effort to manage, but the cost is higher and the effect is not ...

AI Technical Summary

Problems solved by technology

On the one hand, it is due to the damage to the water ecosystem caused by the hard revetment, and on the other hand, due to the effect of the river tide, emergent plants and submerged plants cannot survive, while floating plants are difficult to maintain, and finally make the hard revetment channel A water ecosystem with low cost of components is difficult to realize

[0004] When the tidal drop is small and the water flow velocity is low, the water ecosystem can be restored by building cofferdams with hard gabions to establish an ecosystem. In large cases, the method of building cofferdams with gabions to form ecological restoration areas is not suitable

Because the existing methods of building cofferdams with hard gabions are usually blind operations due to the deep water depth, the constructed cofferdams cannot be shaped and cannot be recycled after ecological restoration
