Embodiment 1

[0025] Such as figure 1 As shown, the overall recovery model structure is divided into the following parts:

[0026] The slope along the river will be cleaned according to local conditions to remove metals, weeds, stones, garbage and other foreign objects that hinder the construction. If any snails are found, they are also picked up and burned. Aquatic plant purification zone 7 is set up below the high water level of the river bank, aquatic floating leaf plants 8 are planted below the normal water level, and high stem emergent plants 2 are planted above the normal water level and below the high water level. The planting methods are all natural scattered and close planting, with a density of 60-80 Plants / square meter.

[0027] Above the high water level, there is a water bank soil fixation and anti-corrosion area 1, which is paved with ecological permeable bricks leaning on the slope, with a width of 1 to 2 meters.

[0028] The water forest restoration area 6 is set up on th...

Abstract

The invention discloses a Binjiang touring type wetland revegetation mode structure. The Binjiang touring type wetland revegetation mode structure is characterized in that in a river bank, an aquatic plant purifying region is arranged below a high water level, a water edge soil fixation and erosion preventing region is arranged above the high water level, and an overwater forest recovery region is arranged on one far-water side outside the erosion preventing region. In the aquatic plant purifying region, aquatic floating-leaved plants are planted below a normal water level in a naturally scattered growth and close planting mode, and high-stalk emerged plants are planted above the normal water level and below the high water level in a naturally scattered growth and close planting mode. The water edge soil fixation and erosion preventing region is paved with slope protection bricks and the width of the water edge soil fixation and erosion preventing region ranges from 2m to 3m. The overwater forest recovery region is of an ecological simulation community structure formed by natural mixing of wetland trees and shrubs to achieve height matching, color combination, advantage and disadvantage complementation and calobiosis. Touring footpaths and seats for rest are naturally arranged in the river direction in communities. Through meticulous engineering design and scientific plant matching, the Binjiang touring type wetland revegetation mode structure achieves perfect combination of Binjiang hydraulic engineering and wetland revegetation, is important for river bank wetland soil fixation and erosion preventing and environment improvement, and has the advantages of being ecological, beautiful and multifunctional and increasing effect.

Description

technical field [0001] The invention relates to a riverside sightseeing type wetland restoration model structure, which belongs to the technical field of wetland ecological restoration and urban gardening. Background technique [0002] Wetlands are unique ecosystems formed by the interaction of land and water on the earth. Wetlands have economic, social and ecological benefits. Wetlands can maintain a water storage capacity that is 3 to 9 times or even higher than the weight of the soil itself, so it can prevent and delay floods and regulate river runoff; wetlands contain a large amount of peat, and when water flows through wetlands, the pollutants contained in them will be eliminated. It is degraded by adsorption or biochemical reaction, which is beneficial to keep the water clean. In addition, wetlands contain rich animal and plant resources and play an important role in maintaining biodiversity in the waterfront zone. [0003] There is a considerable area of ​​riverban...
