Description
First, technical field
The present invention relates to river environment field, particularly a kind of river microhabitat improves system and method.
2nd, background technology
Groynes（spur）, it is the river regulating structure that or oblique orthogonal with riverbank is stretched into river also known as " deflecting flow dam ".The dam
End connect with embankment in T-shaped.Groynes can divide submerged breakwater or non-submerged breakwater, and in design, diving dam crest can cross water, non-
Diving dam crest cannot cross water.The permeable title permeable spur of dam body, it is fluid-tight to claim waterproof groynes.Waterproof groynes controls flow
Effect is stronger, is paved and formed by building stones, earth material, concrete prefabricated element or mattress sinking.Permeable spur a part of flow can be chosen from
Riverbank starts to control and leads flow action, and another part flow flows to dam field through groynes, slows down flow velocity, makes sedimentation, and unhurried current falls silt
Effect is preferable.
The groynes group of riverbank setting, the waters between two groynes substantially belong to hydrostatic region, then this region
For water oxygen content with regard to extremely low, the oxygen content of water is the necessary living environment of some aquatiles again, oxygen content is low may result in it is aquatic
Biology cannot well survive, then the water quality in this region can be worse and worse so that existing river habitat is relatively single.Therefore,
The problem of improvement in river habitat is current urgent need to resolve.
3rd, invention content
For the above situation, to solve the defect of the prior art, the purpose of the present invention, which is just to provide a kind of river microhabitat, to be improved
System and method can effectively solve the problems, such as that existing river habitat is single.
The technical solution that the present invention solves is that improving system and water flowing including water plant improves system, water plant
Improvement system is made of the water plant planting area of the planting aquatic plants above, the water plant photosynthesis release oxygen of plantation
Gas and water cycle is made to get up to improve the dissolved oxygen content in waters between groynes group, it is each that water plant planting area is arranged on groynes group
Hydrostatic region between groynes and on the slope of each groynes, expands cultivated area, makes the water body in the waters around this molten
Oxygen amount improve, improve water quality, solves the problems, such as that river microhabitat is monistic, water flowing improve system including shoal, Gravels and
Deep trouth, shoal are arranged on the hydrostatic region between each groynes of groynes group, and water plant planting area is arranged on the shallow of hydrostatic region
Wriggle the deep trouth for opening up and stretching into and be pierced by between the oriented each groynes of groynes group on beach, on shoal, and deep trouth is flowed convenient for flow, carried
The mobility of Gao Shui, shoal are equipped with the first Gravels, and the first Gravels are surrounded by the deep trouth between each groynes of groynes group, the
One Gravels, which can improve, to purify water.
River microhabitat ameliorative way is to improve system using river microhabitat, is then carried out according to the following steps：
1）Shoal below groynes group is obliquely installed along water (flow) direction, ensure water can proper flow, opened on shoal
If hydrostatic region extension of the deep trouth between each groynes of groynes group, then through out so that flowing water can be from groynes
It is flowed through in the intermediate inner lead of group, improves water cycle, inner lead is made also to move up, improve dissolved oxygen amount；
2）First Gravels, the slope of single groynes are set on the shoal of the deep trouth enclosing region between each groynes of groynes group
The second Gravels of upper setting；
3）Planting aquatic plants on the first Gravels and the second Gravels in water plant planting area, the water plant of plantation
Photosynthesis discharges oxygen and water cycle is made to get up to improve the dissolved oxygen amount in waters between groynes group.
The present invention makes inner lead also move up, and improves water cycle, improves the mobility of water, improves dissolved oxygen amount, the water of plantation
Plant photosynthesis discharges oxygen and water cycle is made to get up to improve the oxygen content in waters between groynes group, therefore improve water
Matter efficiently solves the problems, such as that river microhabitat is monistic, is the innovation on river microhabitat improvement system and method.

Water cycle is made to get up to improve the dissolved oxygen content in waters between groynes group, water plant planting area 3 is arranged on 1 each fourth of groynes group
Hydrostatic region between dam and on the slope of each groynes, expands cultivated area, makes the water body dissolved oxygen in the waters around this
Amount improves, and improves water quality, solves the problems, such as that river microhabitat is monistic, and water flowing improves system and includes shoal 2, Gravels and depth
Slot 5, shoal 2 are arranged on the hydrostatic region between 1 each groynes of groynes group, and water plant planting area 3 is arranged on hydrostatic region
Wriggle the deep trouth 5 for opening up and stretching into and be pierced by between oriented 1 each groynes of groynes group on shoal 2, on shoal 2, and deep trouth 5 is convenient for flow
Flowing, improves the mobility of water, and shoal 2 is equipped with the first Gravels 4a, the first Gravels 4a by between 1 each groynes of groynes group
Deep trouth 5 surround, the first Gravels 4a, which can improve, to purify water.
In order to ensure using effect, the single groynes of the groynes group 1 is arranged to trapezium structure, the slope of single groynes
Water quality can be improved by being equipped with the second Gravels 4b, the second Gravels 4b.
The height at the top in the shoal 2 is continuously decreased along water (flow) direction, it is ensured that the flow on shoal 2 can
Water (flow) direction along river flows, and improves the mobility of the water in 1 hydrostatic region of groynes group, can also increase the dissolved oxygen amount of water,
Improve water quality, solve the problems, such as that river microhabitat is monistic.
The outward opening of deep trouth 5 between each groynes of groynes group opens wide and opposite water (flow) direction.
First Gravels 4a, the second Gravels 4b may be contained in water plant planting area 3.
River microhabitat ameliorative way is to improve system using river microhabitat, is then carried out according to the following steps：
1）Shoal 2 below groynes group 1 is obliquely installed along water (flow) direction, ensure water can proper flow, on shoal 2
Hydrostatic region extension of the deep trouth 5 between 1 each groynes of groynes group is opened up, then through out so that flowing water can be from
It is flowed through in inner lead among groynes group 1, improves water cycle, inner lead is made also to move up, improve dissolved oxygen amount；
2）First Gravels 4a, single groynes are set on the shoal 2 of 5 enclosing region of deep trouth between 1 each groynes of groynes group
Slope on the second Gravels 4b is set；
3）Planting aquatic plants on the first Gravels 4a and the second Gravels 4b in water plant planting area 3, the water of plantation
Plant photosynthesis discharges oxygen and water cycle is made to get up to improve the dissolved oxygen amount in waters between groynes group.
