Problems solved by technology

[0003] At present, the ecological restoration methods for the reservoir-tang type wetland drawdown zone are mostly based on certain terrain transformation, and the method of restoring a single vegetation community is used. However, due to factors such as water level elevation and flooding stress, the growth of vegetation is affected, and the restoration effect has not been achieved. reach the ideal state
Especially for reservoir and pond slopes with large water level changes, the repair effect is not obvious. In addition, there is "A Method for Ecological Restoration and Water Quality Purification Efficiency Improvement of River Fluctuation Zone in Reservoir" in the existing technology. The core of this technical method is It is to use the side slope of the water-fluctuating zone of the reservoir to transform the intercepting weir and create a beach for the growth of aquatic plants. This technical method is suitable for the treatment of the water-fluctuating zone of rivers entering the reservoir with gentle slope terrain.
However, it is not applicable to the sinking zone of other steeper pond wetlands in the reservoir
The related technology "Ecological Restoration and Soil and Water Conservation Method of Wide Gentle Slope Fluctuation Zone of Large-scale Water Conservancy Project" is used in the ecological restoration of wide gentle slope hydrofluctuation zone of large-scale water conservancy project, but it is not applicable to the ecological restoration of general hydrofluctuation zone

Embodiment 1

[0027] refer to Figure 1 to Figure 4 , an ecological restoration structure of reservoir and pond water-fluctuation zone based on bionic micro-cave habitat modification, comprising a water-fluctuation zone 100 and a bionic cave structure arranged on the water-fluctuation zone 100, the slope of the water-fluctuation zone 100 is ≥ 60 °, a seed bank 600 and an arbor 700 are placed in the bionic cave structure. The bionic cave structure retains part of the water-fluctuating zone soil moisture and some nutrients, and intercepts part of the nutrients in the water, providing growth conditions for the seed bank and trees in the hydrofluctuating zone, making the habitat of the bionic cave in the water-fluctuating zone more favorable for plants Survival and biological habitat, for example, some amphibians live in the cave, and some other microorganisms live in the cave, creating a bionic habitat to achieve the effect of ecological restoration.

Embodiment 2

[0031] Embodiment 2: A bionic micro-cavity habitat transformation method for ecological restoration of reservoir and pond water-fluctuation zones. A bionic cave structure is constructed on the upstream surface of the water-fluctuation zone 100 and a seed bank 600 is placed in the bionic cave structure.

[0032] When the soil on the surface of the water-fluctuation zone 100 is hard or sandy, the soil is treated after the bionic cave structure is constructed.

[0033] The treatment is specifically laying the sludge at the bottom of the hydrofluctuation zone on the bionic cave structure.

Embodiment 3

[0034] Example 3: A bionic micro-cavity habitat transformation method for ecological restoration of reservoir and pond water-fluctuation zone, constructing a bionic cave structure on the upstream surface of the water-fluctuation zone 100 and placing a seed bank 600 in the bionic cave structure.

[0035] When the soil on the surface of the water-fluctuation zone 100 is hard or sandy, the soil is treated after the bionic cave structure is constructed.

[0036]The treatment is specifically adding nutrient soil at the bottom of the bionic cave structure, then placing the seed bank 600, and finally spraying a biomass-based liquefied resin containing 3 wt% foaming agent with a viscosity of 7000mPa. The resin can be purchased lignin-based trialdehyde glue, and the foaming agent can be glycine. After the spraying is completed, wait for the foaming to be completed. During the foaming period, a prefabricated frame can be used to fix it. After the foaming is completed, the prefabricated ...

Abstract

The invention discloses a reservoir and pond hydro-fluctuation belt ecological restoration structure based on bionic micro-cave habitat transformation and a restoration method thereof, and relates to the technical field of hydro-fluctuation belt restoration. The restoration structure comprises a hydro-fluctuation belt and a bionic cave structure arranged on the hydro-fluctuation belt, the slope of the upstream face of the hydro-fluctuation belt is larger than or equal to 60 degrees, and a seed bank is placed in the bionic cave structure. According to the restoration structure, a shallow pit type bionic cave habitat is utilized, porous structure shallow surface transformation is carried out on the hydro-fluctuation belt, and a bionic cave environment suitable for plant growth of the reservoir and pond hydro-fluctuation belt is created. The bionic cave structure retains part of soil moisture and part of nutrients of the hydro-fluctuation belt, the nutrients in part of water are intercepted, growth conditions are provided for the seed bank of the hydro-fluctuation belt, the habitat of the bionic cave of the reservoir and pond hydro-fluctuation belt is more beneficial to plant survival and biological habitat, and the bionic habitat is constructed so as to achieve the ecological restoration effect.

Description
