Description
Technical Field
The invention relates to the technical field of ecological restoration, in particular to a wetland plant matrix for an ecological grid hydro-fluctuation belt and application thereof.
Background
The hydro-fluctuation belt is a staggered belt of aquatic ecosystems such as rivers, lakes and ditches and land ecosystems, is a special area for periodically fluctuating water level, is an ecological barrier for maintaining the health of the biogas environment in rivers, lakes and reservoirs, can effectively absorb land source pollutants, effectively blocks the diffusion of runoff pollutants to water bodies, and has important ecological functions. The wetland vegetation of the hydro-fluctuation belt can effectively intercept and adsorb nitrogen and phosphorus nutrition and toxic and harmful pollutants carried by the surface runoff, and prevent water pollution. Meanwhile, the plant root system can form a crosslinking effect with soil microorganisms, so that the nitrification and denitrification of the microorganisms and the phosphorus metabolism are promoted, the nitrogen and phosphorus nutrition is reduced, and the toxicity of toxic pollutants is passivated. In addition, the plant root system and the soil matrix form a firm biophysical embedded structure, so that on one hand, water flow scouring is resisted, water and soil conservation is promoted, on the other hand, the flow speed of river water is slowed down, suspended particles of the water body are promoted to settle, and the soil fertility is enhanced, so that the plant growth is promoted. Therefore, the construction, recovery or maintenance of the wetland vegetation of the hydro-fluctuation belt has important significance for maintaining the health of the aquatic ecosystem and the ecological service function.
However, artificial activities such as reclamation and farmland making, sand and stone excavation, land hardening and the like seriously destroy natural hydro-fluctuation belt habitat, the vegetation coverage of the wetland is obviously reduced, and the water continuously washes, so that the soil of the hydro-fluctuation belt losing the vegetation coverage is gradually barren, the natural wetland ecological environment of the hydro-fluctuation belt is seriously degraded, and the ecological service function is thoroughly lost. The wetland vegetation of the hydro-fluctuation belt is constructed by ecologically restoring the hydro-fluctuation belt, so that the ecological service function of the hydro-fluctuation belt can be restored, and the water environment health of rivers, lakes and reservoirs is maintained.
Because the hydro-fluctuation belt tends to have a large gradient, is influenced by water level fluctuation and is impacted by stormy waves for a long time, and the degraded hydro-fluctuation belt is barren in soil quality and is seriously hardened, if a traditional turf laying or slurry spraying method is adopted, plants cannot be effectively bonded with the slope of the hydro-fluctuation belt, the plants cannot be planted and bred, and vegetation recovery cannot be realized.
The prior art mainly uses a mountain side slope vegetation restoration method, firstly, a layer of wire netting is covered for fixation after turf is paved or grass seeds are sprayed, and secondly, porous bricks are paved to form an ecological grid structure, and then wetland plants are transplanted. The two methods can solve the mountain side slope environment mainly affected by rain fall, and have limited effect on solving the vegetation restoration problem of the hydro-fluctuation belt corroded by water flow and wind waves for a long time.
The existing repair technology has the defects, but the ecological environment protection is not sustained, and a new process technology is urgently needed to be put forward to solve the problems.
In summary, how to provide a wetland plant matrix for an ecological grid hydro-fluctuation belt and application thereof is a problem to be solved by those skilled in the art.
