Abstract
The invention discloses a manual restoration method of a hydro-fluctuation belt. A temporary catchwater is arranged at the top of a slope, and the situation that accumulated water is collected to impact on a slope body during rainfall is avoided. Drainage ditches are arranged on the surface of the slope so that the impact of heavy rainfall to the slope body can be reduced. According to the method, the influence of rise and fall of the water level on different vegetational forms is fully considered, and the survival rate of plants is improved. The varieties of wetland plants are enriched, and the biodiversity of wetland and the structural stability of the ecosystem are improved. A degradable plant fiber net is laid in the position, on the upstream batter surface, of the slope body, and therefore the erosion of rainwater to the slope body can be effective buffered. The loss of water, soil and vegetation of the slope body is reduced. When the vegetation grows up to form strong root systems, the plant fiber net can be automatically degraded, no pollution is caused to environment, and organic fertilizer needed in growth of the plants can be further provided. Observation of many years after restoration finds that the vegetation grows well, and the water and soil loss and environmental pollution are effectively controlled.
Description
Technical field
The invention belongs to water protection field, be specifically related to a kind of artificial restorative procedure of falling zone.
Background technology
The quality of falling zone vegetation is that can reservoir the healthy important sign run, and plays an important role in reservoir ecosystem.But, due to reasons such as Reservoir Operation operation and natural conditions, cause reservoir level frequent and fluctuate widely and flooding time long, vegetation easily wrecks at reservoir edge, the particularly anxious and region of soil depletion of, current steep in some gradients, therefore its vegetation may flood disappearance, then mean that Reservoir region loses one ecological protective screen, falling zone there will be the multiple ecological environment problems such as pollution grows worse, soil erosion aggravation, geological disaster be frequent, thus threatens the safety of Reservoir Water Quality and the benign cycle of ecology in reservoir area system.
The problem that current existence is such, the soil of falling zone scope is subject to water body and washes away loss, and the basic condition of plant growth is constantly destroyed, and is difficult to form biocoene.Soil matrix usual gravel concentration in falling zone is higher, grittiness is comparatively strong, and matrix water retaining capacity is very limited, and after water-break, Water deep leaching is serious, causes landform arid to take place frequently, greatly affects plant survival and growth.Wetland plant varieties of plant is relatively single, its planting patterns do not carry out unified standard with efficiently manage, water plant ecology component distribute deficiency rationally, various biology does not form rational in infrastructure, the efficient synthesis of function.
Summary of the invention
The object of the present invention is to provide a kind of artificial restorative procedure of falling zone, effectively can solve the problem of soil erosion, each Plants is made to present obvious change of gradient on falling zone Function of Wetland and landscape effect, make full use of dislocation, differentiation on multiple populations, utilize mutually supplementing of wetland plant populations together to form stable Community composition.
Object of the present invention is achieved by the following technical programs:
An artificial restorative procedure for falling zone, comprising:
(1) when water level is minimum, to falling zone meet water domatic place under repair smooth, cleaning, compacting; Arrange interim catchwater on top, slope after domatic finishing, when preventing rainfall, ponding collects and impacts slope body;
(2) on the outer slope of falling zone, a drain is repaiied every 2 ~ 3m;
(3) outer slope top, falling zone plantation weeping willow, shelter belt is formed;
(4) meet water in falling zone the domatic ecological region planting tuber of dwarf lilyturf of the degree of depth lower than 2.5m of disappearing;
(5) the domatic degree of depth that disappears that meets water in falling zone is ecological region planting vetiver or the Paspalum distichum of 2.5 ~ 5m;
(6) the domatic degree of depth that disappears that meets water in falling zone is greater than the ecological region planting Hemarthria compressa of 5m;
(7) select dry season, select and sow grass seeds by duster or smear the mode broadcast and plant;
(8) before the wet season arrives, when the plant of plantation all emerges, the slope body meeting water domatic lays degradable plant fiber net.
In the artificial restorative procedure of aforementioned falling zone, described interim catchwater communicates with drain, reduces interim the washing away slope body of heavy rain.
In the artificial restorative procedure of aforementioned falling zone, the described planting time will apart from least 35 days wet seasons.
In the artificial restorative procedure of aforementioned falling zone, the wire diameter of described vegetable fibre net is 0.4 ~ 0.6cm, width of mesh be 2 ~ 6cm.
The invention has the beneficial effects as follows:
(1) arrange interim catchwater on top, slope, when preventing rainfall, ponding collects and impacts slope body.Gutter is set on domatic and can reduces the impact of precipitation to slope body.
(2) outer slope top, falling zone plantation weeping willow, while forming shelter belt, also there is stronger ornamental value.
(3) the present invention takes into full account that fluctuation in stage affects different vegetation types, improves plant survival rate.Enrich wetland plant kind, promote Wetland Biodiversity and ecosystem structure stability.
(4) on the slope body meeting water domatic, lay degradable plant fiber net, effectively can cushion rainwater washing away slope body.Reduce slope body water and soil and vegetation loss.After vegetation has grown up and forms stronger root system, vegetable fibre net has been degraded automatically, to environment, can not can also provide required fertilizer, kill two birds with one stone for plant growth.
