A kind of restoration of the ecosystem device that improves water surrounding
The utility model relates to water surrounding ecological reestablishment field, is specifically related to a kind of for improving the restoration of the ecosystem device of water surrounding.
The main Ecological Measures of water surrounding reparation is structure and the reparation of aquatic ecosystem, and its core is the biocenological structure of water body.At present conventionally biological floating bedly make part waterplant obtain nature to recover.Biological floating bedly by the waterplant of planting in floating bed, nutritive substance excessive in water body is absorbed, reduce the loads of nutrition of water surrounding, simultaneously the root system of waterplant, for plankton and microorganism provide the carrier that adheres to existence in water body, builds significant for water environment biological group.But the method has the limitation of following several respects:
1. cannot carry out three-dimensional improvement to water surrounding.Biological floating bed main plantation emergent at present, relies on the emergent root system being present in water body and carries out water surrounding improvement.And most of research shows, have good submerged vegetation and be only a healthy aquatic ecosystem.Also there is at present the outstanding bed that recovers design for submerged vegetation, similar with traditional floating bed, often attend to one thing and lose sight of another, cannot accomplish that very water vegetation and submerged vegetation recover simultaneously, cannot improve reparation to water surrounding from upper strata water body and lower floor's water body two aspects simultaneously.
2. ignore the improvement effect of bottom-dwelling to water surrounding.At present biological floating bed main utilization be the improvement effect of waterplant to water body.But the ecosystem not only only needs the green plants as the producer, also needs human consumer and decomposer, just can complete material cycle and flow of energy, become complete food chain, make the operation that the ecosystem can be good.Otherwise the producer accumulates excessive power and material also can cause secondary pollution to water body.The zoobenthos of holding human consumer and decomposer role can reasonably utilize the producer, and purification of water quality is also had to good result.
Summary of the invention
What order of the present utility model was to provide is to overcome the deficiencies in the prior art, a kind of restoration of the ecosystem device that improves water surrounding is provided, can realize at target water body and building from the water surface to water-bed stereo ecological system, comprise complete food chain, be conducive to structure and the reparation of water surrounding ecology.
For achieving the above object, the utility model is by the following technical solutions:
A kind of restoration of the ecosystem device that improves water surrounding, comprise buoyancy aid framework, described buoyancy aid framework is made up of with the right cylinder that is positioned at these housing central authorities the housing of a bowl type, the upper limb of housing is provided with buoyancy aid, right cylinder upper surface is provided with emergent bed, on emergent bed, has emergent, is provided with submerged plant bed on the inwall of housing, on submerged plant bed, there is submerged plant, in buoyancy aid framework, also have zoobenthos.
Further, described submerged plant bed is made up of multilayer fishing net, and submerged plant planting is on the fishing net of inner side.
Further, described submerged plant bed is made up of the corrosion-resistant fishing net of 4-5 layer, is fixed on housing inwall by band.
Further, described emergent bed is reticulated structure, and emergent is planted in grid.
Further, the grid aperture of described emergent bed is 2-8cm.
Further, the material of described emergent bed is PE or similar environment-friendly materials with it.
Further, the upper surface of described buoyancy aid framework is coated with fishing net.
Further, the sidewall of described housing and the angle of cylindrical vertical surface between 45 ° ~ 75 °, preferably 60 °.
Further, seal by fishing net the bottom of described buoyancy aid framework.
Further, described emergent is indigenous species plant or the stronger plant of patience, as iris, calamus, arrowhead, hay grass, reed etc.; Described submerged plant is the common submerged plants such as watermifoil, hornwort, bitter algae, black algae, water caltrop; Described zoobenthos is mollusk, as river warship, ring rib spiral shell, lamnaeid, China circle river snail etc.
The beneficial effects of the utility model:
The utility model, compared with existing ecological reestablishment, has following advantage:
1. pair water surrounding is carried out solid reparation.The emergent on water body top layer, and the ecological structure of the submerged plant simulating nature water surrounding of lower floor in water body, upper, middle and lower is taken into account, comprehensive reparation water surrounding.
2. zoobenthos, wetland plant are introduced to ecological reestablishment, zooplankton also can see through in fishing net access to plant simultaneously, carry out growth and breeding, introduce in restoration of the ecosystem by complete food chain, emphasize the circulation of material and flowing of energy, complete food chain is conducive to the reduction of water surrounding ecological recovery and pollution load.
3. device enters the water body initial stage and can take food submerged plant and zoobenthos by anti-water-stop body Mesichthyes, animals and plants recovery effects in assurance device.
4. landscape effect is good, lookes far into the distance emergent, closely sees submerged plant, and the water surface all has beautiful scenery up and down.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of buoyancy aid framework;
Fig. 3 is the frontview of buoyancy aid framework.
In figure, 1-buoyancy aid framework, 101-housing, 102-right cylinder, 2-emergent bed, 3-emergent, 4-submerged plant bed, 5-submerged plant, 6-zoobenthos, 7-buoyancy aid, 8-fishing net.
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in drawings, improve the restoration of the ecosystem device of water surrounding, comprise buoyancy aid framework 1, buoyancy aid framework 1 is made up of the housing 101 of a bowl type (up big and down small horn-like) and the right cylinder 102 that is positioned at these housing central authorities, the upper limb of housing 101 is provided with buoyancy aid 7, right cylinder 102 upper surfaces are provided with emergent bed 2, on emergent bed 2, there is emergent 3, on the inwall of housing 101, be provided with submerged plant bed 4, on submerged plant bed 4, there is submerged plant 5, in buoyancy aid framework 1, also has zoobenthos 6, the coexist region under water of buoyancy aid framework 1 of zoobenthos 6 and submerged plant 5.
Submerged plant bed 4 is made up of multilayer fishing net 8, and 5 kinds of submerged plants are planted on the fishing net of inner side.
Submerged plant bed 4 is made up of the corrosion-resistant fishing net of 4-5 layer, is fixed on housing 101 inwalls by band.
Emergent bed 2 is reticulated structure, and 3 kinds of emergents are planted in grid.
The grid aperture of emergent bed 2 is 2-8cm.
The material of emergent bed 2 is PE or similar environment-friendly materials with it, also can be bundled into fenestral fabric as bamboo clappers with natural materials.。
The upper surface of buoyancy aid framework 1 is coated with fishing net, prevents from that zoobenthos flight and extraneous fish from entering to take food submerged plant 5.
The angle of the vertical surface of the sidewall of housing 101 and right cylinder 102, between 45 ° ~ 75 °, is preferably 60 °.
Seal by fishing net the bottom of buoyancy aid framework 1.
Emergent 3 can be selected indigenous species plant or the stronger plant of patience, as iris, calamus, arrowhead, hay grass, reed etc.; Submerged plant 5 can be selected the common submerged plants such as watermifoil, hornwort, bitter algae, black algae, water caltrop; Zoobenthos 6 can select mollusk as river warship, ring rib spiral shell, lamnaeid, China circle river snail etc., is eaten and scraped food effect to reduce plant plankton and plant residue amount in water body by the filter of zoobenthos, reaches the effect that alleviates water body load.
