Description
Technical Field

Background
The natural ecosystem can be seen as being composed of three subsystems of water (water body), soil (soil) and gas (atmosphere). According to the theory of system ecology: driven by solar energy, energy and matter circulate between these subsystems through the effects of physical, chemical, and vital activities. Has stable and unobstructed energy and material flow process, and is a basic condition of a healthy ecosystem. Due to the interference of human activities, the flow process of energy and materials of the original ecological system changes, which causes the disturbance of energy and material communication between systems and finally leads to the ecological collapse of the whole ecological system. The flow of energy and materials in water, soil, and gas systems requires the crossing of interfaces (interfaces). Organisms (plants, animals, microorganisms) and their activities are important carriers and driving forces for driving the flow of energy and substances at the interface. The discipline of studying the material and energy exchange, information transfer and their interaction with media between organisms and environments, at the interface between organisms and environments, can be called interface ecology. On the damaged 'interface', the artificial forward intervention (ecological restoration) is applied to restore the ecological function of the interface, open the flow of energy and substances and accelerate the realization of the self-restoration capability of the system.
The surface of the ground with serious desertification and water and soil loss, the surface layer of the mined mine and the like are typically damaged soil-air interfaces, and the restoration of surface vegetation is the key for restoring the ecological system of the type, but the plants are difficult to be re-planted and grow on the surface layer of the soil with hardened soil, sand (sand) quality, water retention failure, lack of nitrogen and phosphorus nutrition, lack of organic matters (carbon sources) and trace minerals.
The silty bottom of a polluted river or water body, the river bank affected by the sailing waves, and the like are water-soil 'interfaces' which need to be repaired. The release of nitrogen and phosphorus nutrients for preventing the sludge of the polluted river or water body from being released into the water body is an important way for treating the endogenous pollution of the water body; compared with the revetment of cement or wood piles, the ecological revetment not only prevents the erosion of the river bank influenced by the waves of the sailing ship, but also improves the biological diversity and the landscape function, and is the development trend of modern water engineering and ecological restoration technology. How to reduce the release of nitrogen and phosphorus nutrients of the sludge of the polluted river or water body to the water body, provide an aerobic microbial habitat at the bottom sludge and water interface, and economically and rapidly recover submerged plant or emergent plant communities in the water body is a key point of attention.

All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Example 1
The present embodiment provides a base material, which is composed of at least one fiber material, and the fiber material is distributed in a shingled manner, so that the base material is in a 3D structure and has a first porosity and a first thickness.
Specifically, referring to the schematic structural diagram of the substrate shown in fig. 1, the substrate is preferably composed of a scaffold fiber 1, a plant fiber and an environmentally friendly bonding fiber 2, wherein the scaffold fiber 1 is composed of a high modulus coarse fiber for supporting a 3D framework of the substrate; the animal fiber is wool, etc.; the plant fiber is composed of one or more of hemp, coconut, bamboo and reed, and the environment-friendly bonding fiber is preferably polypropylene.
The support fiber 1, the animal-plant fiber and the environment-friendly bonding fiber 2 are mutually interwoven together like a tile in a stacking manner to be distributed in a tile-shaped manner, so that a 3D structure similar to a bird nest is formed, a 3D framework of the base material is ensured, certain gaps are formed in the base material, and the improvement of the internal circulation of the base material is facilitated.
The substrate of the present embodiment is required to have a first porosity, which is used to ensure a certain gap inside the substrate and a certain stability, so as to facilitate material circulation, species fixation and environmental adaptation.
In one embodiment, when the substrate is laid at the bottom of the water, that is, when the substrate is located at the interface between water and soil, the first looseness can satisfy that the root system of the aquatic plant is stable in the substrate, the substrate cannot be dispersed and deformed under the action of the buoyancy of the water body, and the water can circulate in the substrate. In another embodiment, when the substrate is laid on the ground surface, that is, when the substrate is located at the interface between the atmosphere and the soil, the first porosity can satisfy the requirement that the plant root system is stabilized in the substrate, and the inside of the substrate has certain water storage property, moisture retention property and air circulation property, for example, the first porosity can be embodied by the apparent density of each fiber material constituting the substrate in the substrate, and for example, the apparent density of the scaffold fiber, the animal and plant fiber and the environment-friendly fiber in the substrate is respectively: 5 to 15kg/m3,15～25kg/m3,25～35kg/m3. More specifically, the apparent density of the scaffold fiber was 10kg/m3The apparent density of the animal and plant fibers is 20kg/m3Apparent density of 30kg/m for environmentally friendly fibers such as hot melt adhesive fibers3. Of course, it is understood that the first porosity may be expressed by other means, such as by the porosity of the substrate or the apparent density of the substrate as a whole, and the invention is not limited thereto.
The substrate of the present embodiment also needs to have a first thickness, which is used to make the substrate have enough space inside, so as to satisfy the other requirements of species development and the like.

Since the bulk apparent density is a variation of the porosity, in this embodiment, the porosity of the middle portion of the substrate corresponding to the second portion h2 is less than the porosity of the upper portion and the lower portion of the substrate, respectively, i.e., the upper and lower portions of the substrate in fig. 1 are more porous than the middle portion of the substrate, and are more conducive to fluid communication, while the middle portion of the substrate is more dense than the upper and lower portions of the substrate, and is conducive to the fixation of species and substances placed therein.

2) preparing a matrix: dispersing a functional regulating material in the void space of the base material in the step 1) to prepare a matrix with ecological function; the functional adjusting material is one or a mixture of more of vermiculite, perlite, bentonite, weathered coal, humic acid and water retention material;
3) implantation into a plant species: implanting plant species into the matrix prepared in the step 2) to obtain the ecological interface restoration system.
