Embodiment 1

[0024] Taking Miaodao waters in Shandong Province as an example, the ecological environment and food web composite restoration technology will be implemented in the surrounding waters of Miaodao Islands:

[0025] (1) Determine the key species for the natural restoration of the ecosystem:

[0026] The local dominant species of hexaline hexalis was selected as the key species for the natural restoration of the ecosystem.

[0027] (2) Set up the artificial reef layout scheme to obtain the suitable flow rate for the habitat:

[0028] a. Make a pyramid-shaped fish reef model: the pyramid-shaped fish reef model uses acrylic plexiglass instead of reinforced concrete; the scale ratio of the model is taken as λL=1.9 / the actual thickness of the disc, and the physical reef is reduced into a model reef according to the scale λL ; Install 72 discs on the surface and inside of the model, and polish the discs with acrylic glass, with a specification of 1.9mm;

[0029] b. Set the layout of ...

Abstract

The invention relates to the technical field of ecological restoration, in particular to a cooperative restoration method for reconstruction of a food web of a marine ranch. Comprising the following steps: (1) determining key species for natural restoration of an ecological system; (2) an artificial fish reef layout scheme is set, and the habitat appropriate flow velocity is obtained; and (3) implementing a repairing scheme. According to the method, an artificial culture and proliferation facility arrangement mode with a scientific basis and the number of fishes suitable for releasing are obtained, and scientific reconstruction and collaborative restoration of the food net of the marine ranch are achieved.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a collaborative restoration method for reconfiguration of marine pasture food webs. Background technique [0002] The restoration of coastal waters ecosystem and the conservation of biological resources are mainly the restoration, improvement or reconstruction of single biological resources or ecological environment conditions on a local scale. This technology lacks basic ecosystem components: physical substrates and producers, which can easily cause the loss of released fishery resource populations, greatly reducing the effect of marine ecosystem restoration and fishery resource restoration and conservation. That is to say, it not only ignores the interaction between the structure and process of the ecosystem under the two-way action of multiple stresses and restoration measures at multiple local scales, but also ignores the relationship between different types of...
