Abstract
Disclosed is a vetiver grass double layer reinforced composite vegetation hydro-fluctuation belt flexible plate protection system. A first layer reinforced net is fixedly installed in a hydro-fluctuation belt slope face where vetiver grass is planted to form a plant stem portion reinforced plate. A second layer reinforced net is laid below hydro-fluctuation belt surface soil. Short water logging resistant ground cover plants are planted. The second layer reinforced net is laid below the soil surface so that a root reinforced plate of a root system of the plants is formed. The water logging resistant ground cover plants are the vetiver grass, Bermuda grass, paspalum natatum and the like. According to the vetiver grass double layer reinforced composite vegetation hydro-fluctuation belt flexible plate protection system, and an effective flexible protection plate is formed on the surface of a hydro-fluctuation belt so that two layers of net-shaped protection systems with high integrity are formed on the ground and under the ground. The two layers of net-shaped protection systems are locked with each other tightly through the biological anchoring function of the root system of the plants so that deformation of the hydro-fluctuation belt slope face can be adapted effectively, and therefore a permanent ecological protection function is achieved to the hydro-fluctuation belt by the water logging resistant plants and the plant reinforced flexible plate.
Description
Technical field
The utility model relates to a kind of ecological protection device, is a kind of flexible plate protection system in vetiver double-layer reinforced composite plant cover falling zone for the falling zone slope ecological recovery.
Background technology
The fluctuation in stage band of reservoir is called again the falling zone, refers to be submerged because seasonal fluctuation in stage makes the reservoir periphery one section special area that the soil surfaces.According to statistics, after the normal operation in reservoir area of Three Gorges, in the two sides, reservoir area of 145 meters to 175 meters of height above sea level, form the fluctuation in stage amplitude up to 30 meters, the reservoir drawdown band wetland of more than 400 square kilometre of area.
Three Gorges Reservoir falling zone environmental engineering; it is one of very important engineering roadblock of Yangtze River waterway water and soil conservation; the bank protecting method that adopts at present has the various ways such as concrete revetment, mortar flag stone and dry-laid rubble bank protection, skeleton bank protection; these methods all can play certain engineering protection effect; but it is high generally to have cost; difficulty of construction is large; be difficult for the defectives such as spread; especially said method is all single engineering protections; there is no the biological protection effect of environmental protection greening, it is the focus of paying close attention to both at home and abroad that the Three Gorges Reservoir wetland is administered always.
Wet land system protection test district, falling zone is set up in the reservoir area of Three Gorges; explore the effective measures that ecological protection is built; this is to Three Gorges Reservoir and middle and lower reach of Yangtze River ecology and Environmental security; tool is of great significance; adopt ecological protection to carry out the improvement of falling zone; can reach the effect of putting things right once and for all, also will fill up simultaneously the particularly blank of falling zone research of China and even world's large-sized artificial wetland.
Summary of the invention
Technical problem to be solved in the utility model is to provide the flexible plate protection system in a kind of vetiver double-layer reinforced composite plant cover falling zone, can solve falling zone ecological protection hard problem, form all-in-one-piece net vertical protective structure, permanent ecological protective functions is finally played in the falling zone.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
The flexible plate protection system in a kind of vetiver double-layer reinforced composite plant cover falling zone, the first floor reinforced bar net be fixedly mounted on the falling zone that kind is implanted with vetiver domatic on, the plantation that keeps at a certain distance away of every strain vetiver, be equipped with second layer reinforced bar net between first floor reinforced bar net and falling zone are domatic, the domatic upper mode kind that adopts machinery to spray or manually disseminate in falling zone is implanted with the short water-fast ground cover plant of flooding.
The first floor reinforced bar net is the plane net of large mesh, by Bower Anchor and auxiliary anchoring Dingan County be contained in kind of the falling zone that is implanted with vetiver domatic on.
The plantation spacing of vetiver is 30～50cm.
It is water-fast that to flood ground cover plant be Bermuda grass and/or paspalum notatum.
Second layer reinforced bar net is the stereo ecological protective screening.
Adopt vetiver container seedling technology, cultivate in advance the vetiver container seedling, trade space for time, allow plant grow in advance, in time plantation after the falling zone water level descends improves the anti-water-fast ability of flooding of plant in limited growth time.
The flexible plate protection system in vetiver double-layer reinforced composite plant cover falling zone that the utility model provides, beneficial effect is as follows:
1, utilize second layer reinforced bar net to be carried out reinforcement by plant root whisker over the ground, ground cover plant is adopted the kinds such as vetiver, Bermuda grass, paspalum notatum, thousands of root system of plant and reinforced bar net mutual linking are together, form the root system plate of falling zone flexible biological protection, play the function of surperficial quick protection, form " root system reinforcement plate "; Simultaneously slope table soil is also played the reinforced action of shallow-layer, strengthened tensile strength and the shear strength of overcoat, limited the expansion of " destroying gradually " phenomenon that causes because of the erosion situation, finally limited the generation that rill erosion and shallow-layer slip appear in the slope table.
2, adopt the first floor reinforced bar net to carry out reinforcement to the stem of plant vetiver with certain altitude, along with the growth of vetiver with tiller, plant stem and reinforced bar net mutual linking are together, form the chain system of reinforcement plant of an integral body on the surface, falling zone, be referred to as " stem's reinforcement plate " biological rivet effect of the long root system of vetiver in addition, the final vetiver double-layer reinforced composite plant cover anchor layer that forms, this reinforcement vetiver composite plant cover falling zone ecological protection system offsets the effect that band plays the deep layer protection.
3, pass through the stem of plant and the reinforced action of root, form effective flexible protective plate on the surface, falling zone, on the ground with the underground extremely strong netted protection plate of twice globality that formed, the extremely strong netted protection plate of this twice globality is combined together to form composite plant cover reinforcement system closely by the root system anchoring effect of plant again, this composite plant cover reinforcement system protected apron piece has improved greatly anti-impact and has rinsed ability, prevent that soil erosion destroys, and finally plays permanent ecological protective functions to the falling zone.
4, easy construction is quick, constructing does not need special-purpose machines and tools, widely applicable, has great promotion prospect in ecological protection field, falling zone.
5, belong to flexible structure, can adapt to deforming of the slope, compare with traditional arched framework, rhombus lattice, globality is stronger, the phenomenons such as sedimentation, fracture can not occur; Gu soil is effective, protection against erosion is respond well.
6, the function of existing engineering protection can be carried out again biology plantation, does not affect the slope greening plantation, can cover after vegetation forms all domatic, safety, natural beauty.Root system of plant and the flexible protection pad final flexible biological protection pad that forms that mutually intertwines, the fluctuation characteristic that adapts to the falling zone fully again can long-living domatic destructions, reach the biological protection function to the falling zone, and the later stage does not need manual maintenance.
