Abstract
The invention discloses a method for substrate improving in ecological restoration of water bodies.The method is characterized by including following steps: a), excavating longitudinal filling grooves in transverse spaced arrangement on substrates of riverways and lakes according to design, and reserving positions for fixing intercepting plates; b), placing the intercepting plates in the longitudinal filling grooves, back-filling original substrates, compacting, and fixing the intercepting plates, wherein extended portions and buried portions of the intercepting plates are equal in size, and an interval between each two adjacent intercepting plates is determined according to water flowing speed; c), paving a planting soil layer on the substrate of the riverways and the lakes between each two adjacent intercepting plates, slightly pressing, and reserving enough upper-portion space to prevent water loss and soil erosion, wherein thickness of the planting soil layer is inversely proportional to the water flowing speed; d), growing submerged plants on the planting soil layer paved on the substrate of the riverways and the lakes between each two adjacent intercepting plates.The method is suitable for being used in ecological restoration projects of rivers, lakes and landscape water bodies.
Description
Technical field
The present invention relates to a kind of water ecology reparation, particularly relate to a kind of for the method for substrate improvement in water ecology reparation.
Background technology
Along with expanding economy, at present for the repair mode of the water body such as river course, lake gradually chemically, the administration way of physics changes to ecological administration way.The core of ecological management is to realize the reduction of nutrient salt in water by building the complete ecosystem being made up of water plant, aquatic animal, microorganism in water body, thus reaching the purpose of purification of water quality.From ecological angle, submerged plant is the Producer in water body, it not only makes the main force of purification of water quality in water body, habitat and food source can also be provided for aquatic animal simultaneously, and it is favorably improved the dissolved oxygen etc. in water body, as can be seen here, the recovery of submerged plant is the core procedure that water ecology is repaired.
But in actual restoration of the ecosystem, more river course, lake even landscape water body are subject to many-sided impacts such as current are relatively big, the substrate of sandy soil, hard, are unfavorable for growth and the recovery of submerged plant, therefore produce little effect in water ecology reparation.
Summary of the invention
The invention aims to provide a kind of for the method for substrate improvement in water ecology reparation, it not only can be effectively realized the cultivation of submerged plant, and it is smooth that water ecology can also be made to repair.
The present invention is realized in achieve the above object: a kind of of the present invention comprises the following steps for the method for substrate improvement in water ecology reparation:
A) according to design first river course, lake substrate on dig the longitudinal direction landfill mortise with lateral separation arrangement, for the fixing reserved location of intercepter plate；
B) placing intercepter plate in longitudinally landfill mortise, backfill former substrate compacting, fixing intercepter plate, the extension of described intercepter plate is equal with inlet part size, and the spacing between two adjacent intercepter plates is depending on water velocity；
C) substrate in river course between two adjacent intercepter plates, lake lays planting soil layer, light pressure, described plantation the thickness of the layer is that the more little laying depth of water velocity is more big, water velocity is more big, laying depth is more little, reserved enough upper spaces are for anti-current-rush, it is prevented that soil erosion；
D) river course between two adjacent intercepter plates, cultivation submerged plant on the plantation soil layer laid on lake surface sediments.
The extension of described intercepter plate and inlet part size are 200mm, and the spacing between two adjacent intercepter plates is 200-1000mm, and described intercepter plate is mainly made with straw or bamboo plate.
Described river course between two adjacent intercepter plates, lake substrate on to lay the thickness of planting soil layer be 50-200mm.
Described submerged plant is Herba vallisneriae Spiralis, waterweed, p.malaianus and hornwort.
The a kind of of the present invention has the advantage that in actual use for the method for substrate improvement in water ecology reparation
1, a kind of of the present invention fills mortise for the method for substrate improvement in water ecology reparation and the longitudinal direction to dig the fixing intercepter plate of lateral separation arrangement, river course between two adjacent fixing intercepter plates, lake surface sediments are laid planting soil, and cultivate submerged plant thereon, so solve some natural water when being hard (stone substrate, building waste, sandy soil etc.) substrate, submerged plant can not be cultivated, cause the difficult problem that cannot adopt ecological reestablishment purifying water body.
2, a kind of of the present invention have employed fixing intercepter plate for the method for substrate improvement in water ecology reparation, thus overcomes part water body because of water velocity comparatively fast, and makes the submerged plant of new cultivation cannot take root the situation of growth.The planting soil thickness simultaneously laid on the substrate in river course between two adjacent intercepter plates, lake, the more little laying depth of water velocity is more big, water velocity is more big, laying depth is more little, for making top reserve enough spaces, to tackle water impact, avoid soil erosion, in recovering submerged plant process, rotting of the intercepter plate that the later stage is made up of straw or bamboo plate along with main material, also can provide the nutritional labeling needed for growth for submerged plant.
Generally speaking, a kind of method improved for substrate in water ecology reparation of the present invention makes full use of environment friendly biological material and substrate is improved, reaching the cultivation demand of submerged plant, thus completing the restoration of the ecosystem work of water body, and then playing the purpose of water correction.
The a kind of of the present invention is suitable in the Ecological Restoration Project of river, lake, landscape water body to apply for the method for substrate improvement in water ecology reparation.
Accompanying drawing explanation
The concrete structure of the present invention is provided by below example and accompanying drawing thereof.
Fig. 1 is a kind of for the cross-sectional schematic of the method for substrate improvement in water ecology reparation of the present invention.
Detailed description of the invention
Below with reference to accompanying drawing, a kind of of the present invention is described in further detail for the method for substrate improvement in water ecology reparation.
Referring to Fig. 1, during this invention a kind of repairs for water ecology, the method operating procedure of substrate improvement is as follows:
A) according to design first river course, lake substrate 1 on dig the longitudinal direction landfill mortise 2 with lateral separation arrangement, for the fixing reserved location of intercepter plate；
B) in described longitudinally landfill mortise 2, intercepter plate 3 is placed, backfill former substrate compacting, fixing intercepter plate 3, the extension of described intercepter plate 3 is all equal with inlet part size, and respectively 200mm, spacing between two adjacent intercepter plates is depending on water velocity, and the spacing between two adjacent intercepter plates is 200-1000mm, and described intercepter plate 3 is mainly made with straw or bamboo plate；
C) substrate 1 in river course between two adjacent intercepter plates, lake lays planting soil layer 4, light pressure, the thickness of described plantation soil layer 4 is that the more little laying depth of water velocity is more big, water velocity is more big, laying depth is more little, reserved enough upper spaces 5 are for anti-current-rush, it is prevented that soil erosion, the thickness of described plantation soil layer 4 is 50-200mm；
