Description
Technical field
The present invention relates to ecological restoration technical field, and in particular to a kind of Channel slope Ecosystem restoration system.
Background technology
At present, China's rivers, lake and reservoir are generally contaminated, and are still being developed rapidly.Water pollution exacerbates water money
Source shortage, directly threatens the safety of drinking water and the health of the people, influences industrial and agricultural production and Crop securify.According to preliminary
Estimation, economic loss caused by water pollution is about the 1.5%~3% of gross national product.Water pollution become no less than big flood,
Drought even more serious disaster.Water prevention and cure of pollution have become the critical support of national economy sustainable development.
Particularly, urban river is a flowing in urban landscape, is closely connected with life of urban resident environment, and phase
To open Complex Ecological Systems.River to external source pollution with self certain purification recovery capability, but urban river by
Large number of in littoral resident, the production and living of resident cause tremendous influence to urban river, cause urban river ecological functions
Degenerate and lose continuous, black smelly, mosquito occur and grow, the function as urban landscape is not only lost, on the contrary as city
Burden, disturbs the normal production and living of resident, influences city reputation.
In the past few years, many beneficial explorations have been carried out in terms of the protection and reparation of river ecosystem.Pass through river
The measures such as the water and soil conservation in source, water transfer, wetland reparation, make some regional ecosystems be improved significantly.
Chinese patent 201610286970.1 discloses a kind of slope ecological repair system and method, slope ecological reparation system
System includes fill-type ecological blanket and the Seed Layer in the fill-type ecological blanket, the laying that the fill-type ecological blanket is fixed
In in slope surface, and the fill-type ecological blanket includes multiple filling bags being arranged side by side, filling casting resin in the filling bag.Base
Include S1 in the ecological restoring method of the slope ecological repair system, fill-type ecological blanket is laid with slope surface, and use anchor pole
It is fixed；S2, casting resin is filled into fill-type ecological blanket；S3, Seed Layer is set in the fill-type ecological blanket for completing filling, should
Slope ecological repair system and method construction technology are relatively simple, greatly reduce the cost of construction, are beneficial on large area slope
Promoted and applied in the restoration of the ecosystem work in face.But the repair system for repair Channel slope effect be not very significantly, it is right
Sewage disposal in river is acted on than relatively limited.
The content of the invention
The purpose of the present invention is exactly to solve the above-mentioned problems and provides a kind of Channel slope Ecosystem restoration system.
The purpose of the present invention is achieved through the following technical solutions：
A kind of Channel slope Ecosystem restoration system, including it is successively set on clay layer, sand stone layer, the soil on Channel slope surface
Matter layer, organic horizon and vegetation plantation layer, vegetation plantation layer include multiple trapezoidal concrete segments, and described is trapezoidal
Building block hole is equipped with concrete segment, the compost containing organic matter is loaded in the building block hole and plants vegetation, the plant
Drought-enduring plant layer, flooded plant layer, watercress layer and water plant layer are sequentially arranged by plantation layer from top to bottom.
Further, the trapezoidal concrete segment is made by stone and concrete, the stone and concrete
Mass ratio is 1：0.8, gap is very big, maintains preferable permeability and water penetration.
Further, the long side of the trapezoidal concrete segment upwardly, downwards, advise short side by trapezoidal concrete segment
Organic surface is then arranged in, a building block in irregular shape is reserved in each plane of trapezoidal concrete segment
Hole, plant grow out from the cap blocks hole of trapezoidal concrete segment.
Further, hole is formed between the trapezoidal concrete segment, on the one hand the effect of hole is that creation is aerobic
Environment, necessary oxygen is provided for the root system of plant；On the other hand flood current and rainwash are slowed down to Channel slope
Souring, plays the protective effect to Channel slope.
Further, the top of the clay layer, sand stone layer, soil layer and organic horizon covers a layer thickness and is
The overburden layer of 20-30cm, the overburden layer is concordant with the top of Channel slope, the component of overburden layer and the soil property of Channel slope
Component is identical, is effectively covered clay layer, sand stone layer, soil layer, organic horizon and concrete segment layer by overburden layer,
During rainy season, rainwater can enter clay layer, sand stone layer, soil layer, organic horizon and the concrete segment of lower section through overburden layer
Layer；During dry season, overburden layer can also prevent to store water in clay layer, sand stone layer, soil layer, organic horizon and concrete segment layer
The evaporation divided, moisture necessary to preserving growth for plant.
Further, the thickness of the clay layer is 20-30cm, and clay layer act as holding river water, prevents
The a large amount of seepage flow of streamflow.
Further, the thickness of the sand stone layer is 40-50cm, is made of the sandstone that average grain diameter is 3-5cm, sandstone
The main function of layer is preserves moisture, moisture necessary to providing growth for the plant in trapezoidal concrete segment.
Further, the thickness of the soil layer is 40-50cm, and the main component of soil layer is required for plant growth
Normal soil property, for plant root growth provide soil property basis.
Further, the thickness of the organic horizon is 10-20cm, organic horizon according to plant growth characteristics choose with
The best organic matter of plant growth, the main function of organic horizon is, to fertilizer, to be attracted trapezoidal mixed using root system of plant
The root system of plant is grown to Channel slope direction in solidifying earth building blocks, while provides nutrition foundation for the fast-growth of plant.
Further, pedestal is set between the river bed and last trapezoidal concrete segment of row of Channel slope bottom,
The pedestal is made of concrete or stone, and the main function of pedestal is to prevent current scour river bed from causing shadow to concrete segment layer
Ring.
Difference of the invention according to drought and waterlogging season river water level line height, in the trapezoidal concrete segment of Channel slope,
Different plants is planted, in the trapezoidal concrete segment of bottom close to river bed, due to being flooded by current throughout the year, mainly plants water
Plant；In the top of water plant, according to drought and waterlogging season river water level line altitudes, plantation happiness water is planted successively from bottom to top
Thing, flooded plant and drought-enduring plant.During the rainy day, it is not only able to play the souring for slowing down flood current and rainwash, and
And can the rainwash higher to pollutional load play a role in filtering.
Compared with prior art, the present invention is recovering river according to " back to nature " and the river harnessing ideas of " people-oriented "
Meet that resident's activity need carries out control and plan and design to river while original natural functions, form a kind of Channel slope life
State repair system, the system use hierarchical design thinking, are arranged in parallel clay layer, sand along Channel slope successively according to soil function
Rock layers, soil layer and organic horizon, plant layer longitudinal design variety classes plant along vegetation according to plant characteristic, reach and repair river
The purpose of road slope ecological, significant effect, and system structure is simple, cost is low, is easy to be widely applied.
