Step 7: according to wetland elevation difference, planting different water plants, manually put zoobenthos in a suitable place to breed.
The working principle of the invention is, has water front or dykes and dams 200 using two sides or three faces, open waters one side or
Two sides builds submerged breakwater 330 and forms half open waters 300.It is characterized in that slowing down half open waters 300 by construction submerged breakwater 330
Hydrodynamic condition, form the environment of sediment siltation, achieve the effect that promote become silted up and reduce silt loss.Based on being acted on runoff
1m or so below bluish yellow line may be selected in river point bar, the submerged breakwater position of upstream face 320, and 330 elevation of submerged breakwater may be configured as bluish yellow
More than line 0.5~1.0m or so；The submerged breakwater position in the river mouth or coastal region of runoff and trend two-way function, upstream face 320 can
Selection 1m or so, 330 elevation of submerged breakwater below mean low-water may be configured as 310 or more 0.5~1.0m of mean tide tlevel or so.It is latent
The structural shapes such as packed whaleback and jackstone dike can be used in dike 330.To half open 300 hydraulic reclamation silty sand of waters or fine sand, nature is formed
The wetland substrate 510 of the gradient.The hydraulic reclamation lowest elevation in river point bar or channel bar region, river mouth or coastal region is controlled in submerged breakwater height
More than journey 0.5~1.0m.Hydraulic reclamation silt 350 can be waterway dredging soil or capital construction spoir etc..By adjusting 400, dredge pipe line
Set, the modes such as anticipated settlement are to control each region elevation in hydraulic reclamation area and the gradient, lift half open 300 Tidal flat of waters uniformly
It rises；By analysis silty sand and fine sand settlement law, certain anticipated settlement, which is arranged, makes beach face reach expected elevation, and is formed certainly
The right gradient.River water front or the side-blown raising journey of dykes and dams 200 can be controlled in the above 1m of flood level, estuary coast region water front or dykes and dams
200 side-blown raising journeys can be controlled in the above 1m of mean high tide, and the side-blown raising journey of submerged breakwater 330 can control reference standard to be controlled
System, the natural gradient of formation take 1:500~1:1000 according to different soil property situations.Carry out hydraulic reclamation using waterborne or land digging machine
Area 340 flattens, and forms artificial wetland substrate 510, solves the problems, such as 340 ground flat degree of hydraulic reclamation area, by forming expected gradient,
Form artificial natural wetland substrate 510.It is laid with one layer of viscous soil horizon 520 in artificial swamp substrate 510, constructs suitable plant
The environment of growth covers the viscous soil horizon 520 of 10cm~20cm or so in artificial swamp substrate, its role is to be retained sand,
Build the habitat for being suitble to plant to grow naturally.Steel wire grid or rope made of hemp grid or concrete cross are laid on viscous soil horizon 520
Block equipressure protection structure 530, prevents the silt loss on artificial swamp.The steel wire of 30cm × 30cm is laid on the viscous soil horizon of formation
Grid or rope made of hemp grid or concrete hydraulic steering gear adopting cross piece equipressure protection structure 530 avoid drawing the silt flow that brush effect causes hydraulic reclamation because of water flow
It loses, plays the role of soil conservation erosion control, provide basis for water plant planting.According to wetland elevation difference, plant different aquatic
Plant.According to the artificial swamp elevation difference of formation, plants the arbor 540 for being suitble to local natural environment, emergent aquactic plant 550 and sink
Water plant 560, such as willow, reed, lotus, Scirpus tabernaemontani, arrowhead, calamus, rhizoma acori graminei, water lily, floating heart, water shield, wild water chestnut, gold and silver lotus flower
It is suitble to the zoobenthos of local aquatic environment Deng, enhancement releasing, builds the habitat for being suitble to aquatic animals and plants growth reproduction, forms life
State landscape increases the area of river point bar or channel bar wetland, river mouth or seashore beach.The present invention uses submerged breakwater by design to subtract
Slow hydrodynamic condition promotes sediment siltation at beach, and by open enclosing area's hydraulic reclamation silty sand or fine sand, auxiliary leveling, covering to half
It viscous soil horizon and is laid with the measures of pressure protection structure etc. and forms artificial swamp substrate, planting aquatic plants and put zoobenthos in a suitable place to breed to be formed
Ecological wetland landscape, to achieve the effect that increase river point bar or channel bar wetland, river mouth or seashore beach.The present invention was both applicable
In the construction of river point bar artificial swamp, and it is applicable to the construction in river mouth or the artificial beach of seashore, and is waterway dredging soil
Effective use provides wide prospect.
A specific embodiment of the invention is illustrated above, but the present invention is not limited thereto, without departing from
Spirit of the invention, the present invention can also have various change.
