Embodiment 1～5

[0023] A method for configuring multi-stage antifouling plants and microorganisms in shallow lakes, comprising the following steps:

[0024] (1) Building infrastructure: use the river network connected to the shallow lake near the shallow lake to build a gradient water level ecological unit: set up sand washing gates at the shallow lake and the entrance of each river connected to it, Near the water bottom and water surface at a distance of 2-5m from each side, set up reoxygenation aeration devices and water push-flow facilities; excavate and transform the concave areas of the river network above 60° bends to build hierarchical floodplains, and the hierarchical floodplains It connects the upstream and downstream of the river and the height decreases successively, and along the direction of water flow, it includes wet surface areas, wet areas under subsurface flow, and purification areas in sequence, among which water flow gates are set at the entrances and exits connecting the w...

Abstract

The invention discloses a method for preparing multi-level pollution-resistant plants and microorganisms in shallow lakes, wherein the method includes the steps: (1) construction of an infrastructure:constructing a gradient water level ecological unit by utilizing river networks located near the shallow lakes and connected with the shallow lakes; (2) preparation before configuration: adding a filler in a purification area; arranging embankments at lake coasts, river coasts and layered overbank coasts, and burying a soil hardener loaded in a mesh bag in soil near the embankments; (3) microbialpreparation: laying fiber nets on lakes and rivers, and sowing decontamination microbial agents near the fiber nets; and sowing large filamentous green algae to a purification area; (4) plant preparation: arranging submerged plants, floating plants and emergent plants to various areas reasonably; and (5) dynamic regulation: dynamically replenishing seeds or salvaging plants or microorganisms. Thesteps are convenient and simple, the dynamic evolution of an ecosystem is promoted, a multi-level anti-pollution hierarchical structure of a wetland is formed, and the method has high practicality and wide application.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a method for configuring multi-stage pollution-resistant plants and microorganisms in shallow lakes. Background technique [0002] Wetlands are located in the transition zone between terrestrial ecosystems and aquatic ecosystems. They are important ecosystems with many wild animal and plant resources. They have a strong ecological purification effect and have the reputation of "the kidney of the earth". With the development of human society, ecological deterioration is becoming more and more serious, threatening the basis of the existence of the vast biosphere including human beings. Wetland pollution and wetland environment deterioration are one of its manifestations. [0003] The ecological circle of wetlands is relatively rich in biodiversity and has high self-purification ability, especially for light pollution. If the pollution is curbed in time, it can recove...
