Construction method of vegetation-form ecological shallow

Abstract

The invention discloses a construction method of a vegetation-form ecological shallow, and provides the construction method of the multifunctional vegetation-form ecological shallow capable of improving the river flow regime, promoting the restoration of aquatic plants and enhancing water purification. The construction method comprises the following steps: (1) mixing the aggregates with uniform gradation with a binding material and making into hemispherical hollow shallow member units in a mold; (2) filling the hollow parts with aquatic plant cultivation capsules; (3) covering each hemispherical shallow member unit in which the aquatic plant cultivation capsule is placed with another hemispherical shallow member unit to form a spherical unit through adhesion or binding using steel wires; (4) placing a plurality of spherical units in which the aquatic plant cultivation capsules are embedded on the river bed, wherein the bottommost layer of the spherical units are fixed on the river bed by using connecting rods inserted into the river bed; adjacent spherical units on or above the bottom layer are connected with each other through connecting rods. The construction method provided by the invention comprehensively improves the biological habitat conditions in the river channel and facilitates the promotion of integrated improvement of water quality in the river channel and the biological diversity conditions.

Description

technical field [0001] The invention relates to the technical field of resources and environment, in particular to a method for constructing vegetation-type ecological shoals suitable for the field of ecological restoration of rivers and lakes. Background technique [0002] Diversified substrate morphology and hydrodynamic conditions are important factors affecting the habitat conditions of river organisms, which have a strong impact on the structure of biological communities and ecological processes. Under natural conditions, the hydraulic movement of the river has caused the staggered changes of pools and shoals, and correspondingly formed complex flow conditions with rapid and slow changes, which is conducive to the formation of rich and diverse river biomes. However, under the conditions of human disturbance, such as channelization and simplification of river sections, complex section conditions such as river pools and shoals are lost, and river flow regimes are simplifi...

Problems solved by technology

In practical application, there have also been methods such as using film hanging and fillers to improve water quality. The method is characterized by a single function, and it needs to be implemented with auxiliary facilities such as brackets and floating islands, which reduces reliability.
