Embodiment Construction

[0026] like figure 1 Shown:

[0027] The present invention consists of (willow grove green) plant band 1, emergent plant band 2, submerged plant band 3, floating plant band 4, gabion 5, stone setting 6, spherical water-purifying filler 7, stake 8, riprap 9 and It consists of 10 jasmine bushes.

[0028] The focus of this construction method is to construct a waterfront wetland. For the gabion 5 as the boundary, it is made of galvanized and plastic-sprayed wire mesh, and the mesh adopts a regular polygon. The size of filling material is regulated; In gabion 5, fill gravel, fertilizer and the soil that is suitable for plant growth, can plant corresponding plants on gabion 5 like this; Gabion 5 is with stake 8 (φ 150mm, L =2000mm) is fixed on the river bed, and the distance between the wooden piles 8 is 1m, which can effectively ensure the stability of the gabion 5. Gabion 5 is provided with two rows: plant willows on a row of gabions 5 close to the revetment to form willow gre...

Abstract

The invention relates to a vertical revetment river lake water wet land system and a construction method thereof. In the system, two rows of gabions are arranged on revetment and offshore sides to form a water wet land; willows and emergent aquatic plants are planted on the gabions; spherical fillers are arranged on the upstream side; ripraps are filled on the two sides; submerged plants and floating plants are planted in the water wet land to form a submerged plant zone and a floating plant zone respectively; and stones are placed in the water wet land. The system overcomes the defects of vegetation deterioration, reduced biological diversity, water degradation, reduced landscape aesthetic value and the like of the original river lake water zone caused by the reinforced concrete verticalrevetment in the river lake water zone. The system closures pollutants in the water, settles silt carried by the water, purifies water quality, improves water, reduces difficulty of river treatment, lightens load of water treatment, forms vegetation zones, provides a perched space for fishes, and improves biological diversity.

Description

technical field [0001] The invention relates to a river and lakeside wetland system and a construction method for a vertical revetment, belonging to the field of river water environment management and ecological restoration. Background technique [0002] The river and lake waterfront is a type of ecotone of water and land, and it is one of the most fragile wetland ecosystems on the earth. It acts as a buffer zone of filters and barriers for the logistics, energy flow, information flow and biological flow between water and land ecosystems. It can maintain biodiversity and provide wildlife habitats and other special protection functions. At the same time, it can Play the revetment function of stabilizing the lakeshore and controlling soil erosion. In addition, it can provide rich resources, multi-purpose entertainment venues and comfortable environment, that is, economic and aesthetic value. However, with the continuous growth of population and the development of social econ...
