Description
Technical Field
The invention belongs to the technical field of ecological restoration, in particular to a hard shore ecological current-inhibiting system.
Background
As an open water body, a lake is often high in wind and high in wave, the water body is turbid, and floating plants and submerged plants in a beach lake are difficult to survive. In addition, the strong development of the aquaculture industry leads to poor development of the aquatic plant community in the lakeside, which is unfavorable for the self-cleaning function of the lake. Thus, it is necessary to create appropriate habitat conditions.
The stormy waves cause the sediment to suspend, so that a large amount of pollutants in the sediment are released. Under the action of wind waves, pollutants deposited at the river bottom or the lake bottom enter the water body, so that the pollutant load of the water body is further increased. The content of suspended matters in the water body is increased, the transparency is reduced, and therefore, the aquatic higher plants are difficult to obtain the energy required by photosynthesis, so that the endogenous load of the water body is reduced, and the method has important significance for inhibiting the flow of the hard shore and eliminating the water body waves.
The coastal zone is part of the lakeside wetland ecosystem and has the ecological functions of intercepting runoff pollutants, maintaining lake biodiversity and providing wildlife habitat and controlling soil erosion. The research shows that the shoreline shape of the coast zone can influence the effect of wind on the wave and water flow intensity, emergent aquatic plants, submerged plants and the like can reduce the influence of hydrodynamic disturbance on bottom mud, and the effect is more obvious as the plant density is higher. The local micro-habitat difference of the coastline, the depth of the water body, the vegetation coverage and the like is larger.
The existing hard shore current-inhibiting systems at home and abroad belong to artificial rigid structures, such as stone revetments and concrete embankments, and although the problem of erosion along the coastal zone is temporarily solved to a certain extent, the cost is high, and the construction is complex. In addition, the rigid structure also blocks the organic connection between the soil and the external environment, so that the ecological function of the coastal zone soil is seriously damaged. The biological-engineering measures are adopted to inhibit the flow and fix soil, so that the method can be widely applied to the fields of vegetation recovery and the like of river and lake hydro-fluctuation belts, has important practical and long-term significance for ecological environment improvement and water and soil conservation work, and has remarkable social and ecological benefits.
