Embodiment 1:
The specific embodiment of herein described drought-hit area collection rain flood storage tree planting channel, the drought-hit area collection rain are shown referring to Fig. 1-4 Flood storage tree planting channel includes: charge for remittance slope surface 1, gully erosion 2, retaining dam 3 and water collecting sump 4, wherein
The charge for remittance slope surface 1 is located at 2 two sides of gully erosion, can produce earth's surface in rainfall or when deposite snow melts Runoff, charge for remittance slope surface 1 are used to for the rainwash that rainwater and snow-broth are formed being pooled in the gully erosion 2;
The gully erosion 2 is formed by natural rain drop erosion, positioned at the intermediate zone of two sides charge for remittance slope surface 1, is developed on ground Face is hereinafter, for storing rainwater and snow-broth that the charge for remittance slope surface 1 is collected, and rainwash and snowmelt collects field when being rainfall Institute;The gradient α of the gully erosion 21Greater than 0 °;
It is equipped with a retaining dam 3 every preset distance in the gully erosion 2, for intercepting the gully erosion 2 Water is swum, 3 both ends of retaining dam are engaged togather with gully erosion 2, are higher by 2 bottom of trench a certain distance of gully erosion, can The upland water in gully erosion 2 is sufficiently retained, multiple dispersions of retaining dam 3 are laid in gully erosion 2, cut down gully erosion 2 The impact strength of middle and upper reaches water;
It is equipped with a water collecting sump 4 towards the 2 upland water side of gully erosion in each retaining dam 3, for depositing 2 upland water of the gully erosion that the retaining dam 3 intercepts is stored, upland water is stored in the soil in water collecting sump 4;Often 3 quantity of retaining dam in a gully erosion 2 is specifically set as the case may be, is not especially limited here;
Kind is implanted with multiple saplings 5 in each water collecting sump 4, and the quantity of sapling 5 is only schematic in figure, specific sapling 5 quantity are specifically set according to the actual situation, are planted in the soil in water collecting sump 4.It, will by collecting natural precipitation and snowmelt The rainwater harvested is stored in the soil in water collecting sump 4, guarantees surviving for the sapling of plantation.It does not need artificially to irrigate sapling, it is more A retaining dam 3 can sufficiently retain the runoff in channel, reduce the risk of rain flood and soil erosion.
Drought-hit area collection rain flood storage tree planting channel in the present embodiment retains heavy rain using the channel of low-lying natural rain erosion When the rainwash that generates, rainwash is largely retained in channel using retaining dam 3, weakens channel downstream flood calamity The risk that evil occurs.The runoff gathering that rainfall generates is retained in water collecting sump 4 simultaneously, grows utilization for the sapling of plantation, both The ground biomass of drought-hit area is increased, and realizes the greening in deserted mountain gully.The drought-hit area collection rain flood storage tree planting channel of the present embodiment Flood control kind tree is carried out using the gully erosion 2 formed by natural rain drop erosion, the gully erosion 2 naturally occurred has been carried out sufficiently Utilization, solve the problems, such as in the prior art can not resource utilization rain flood and drought-hit area plant trees and survived due to water shortage difficulty Problem, not only environmentally friendly cost but also low.
Embodiment 2:
On the basis of embodiment 1, with continued reference to Fig. 1-Fig. 4 and Fig. 5, the application provides the drought-hit area collection rain again Another embodiment of flood storage tree planting channel.
The gradient α of the charge for remittance slope surface 12It is 9 ° to 45 °, the length of grade a of the charge for remittance slope surface 1 is to protect more than or equal to 10m There is the rainwater of certain volume to be pooled in erosion groove 2 in the form of rainwash when demonstrate,proving aggressivity heavy rainfall.
The width b of the gully erosion 2 is 0.5m to 10m, the depth h of the gully erosion 21It is described for 0.2m to 10m The length c of gully erosion 2 is more than or equal to 10m;It is often referred to shallow ridges and dissected valley, water flow is gradually accumulated by piece stream on the slope Tiny plume forms substantially parallel rill, i.e. shallow ridges (0.5 meter wide, deep 0.1m to 0.4m, long number rice) in earth's surface, by thin The further incision intensification of ditch forms dissected valley.
The retaining dam 3 is earth dam, when for earth dam, can cover wire netting on 3 surface of retaining dam and (not show in figure Out), it prevents retaining dam 3 from being destroyed by rush of water by heavy rain, extends the service life of retaining dam 3.
The cross section of the retaining dam 3 be it is trapezoidal, be arranged to the trapezoidal impact strength for increasing retaining dam 3, the ladder The length d at bottom is 0.3m to 0.5m in shape, and the length e of bottom is 1m to 2m, height h2Equal to the 2 depth h of gully erosion1's 50%-70% not only can guarantee and play the role of intercepting water flow, but also part water flow can be made to flow there through next storage from retaining dam 3 Puddle 4.
Groove 6 (shown in Figure 5) is equipped in the middle part of bottom on the retaining dam 3, can be further ensured that extra water flow can be with Retaining dam 3 is flowed through to next water collecting sump 4, without causing to waste from outflow gully erosion 2;It can guarantee retaining dam again Safety.
The width f of the water collecting sump 4 is 0.1m to 9m, and the length g of the water collecting sump 4 is less than described in adjacent thereto two The distance between retaining dam 3 k.The depth h of the water collecting sump 43For 0.1m to 0.2m, that is, it is lower than 2 bottom 0.1m of gully erosion extremely 0.2m.Soil water-retaining performance in water collecting sump 4 within downward 1 meter is preferable, and the content of the gravel greater than 2 centimetres is below 10%.
The sapling 5 is drought-enduring sapling, and only relying on the moisture stored in water collecting sump soil can survive and grow naturally, such as The drought-enduring tree species such as torch tree, American elm, plant height is between 1 meter to 2 meters, the age of tree is 2 years to 3 years, kind of tree planting in each water collecting sump 5 plants to 10 plants of seedling.
As can be seen from the above embodiments beneficial effect existing for the application is:
The first, drought-hit area collection rain flood storage tree planting channel of the invention retains heavy rain using the channel of low-lying natural rain erosion When the rainwash that generates, rainwash is largely retained in channel using retaining dam, weakens channel downstream flood calamity The risk that evil occurs.
The second, drought-hit area collection rain flood storage tree planting channel of the invention retains the runoff gathering that rainfall generates in water collecting sump, Utilization is grown for the sapling of plantation, had not only increased the ground biomass of drought-hit area, but also realize the greening in deserted mountain gully.
Third, drought-hit area collection rain flood storage tree planting channel of the invention are carried out using the gully erosion formed by natural rain drop erosion Flood control kind tree, has carried out sufficient utilization to the gully erosion naturally occurred, solving in the prior art can not resource utilization The problem of rain flood and drought-hit area are planted trees the problem of being survived due to water shortage difficulty, not only environmentally friendly cost but also low.
Above by drawings and examples, example is passed through to of the invention one although doing to technical solution of the present invention A little specific embodiments are described in detail, but it should be appreciated by those skilled in the art example above is merely to carry out Illustrate, the range being not intended to be limiting of the invention.Although the present invention is described in detail referring to the foregoing embodiments, right For those skilled in the art, it can still modify to technical solution documented by previous embodiment or right Part of technical characteristic is equivalently replaced.All within the spirits and principles of the present invention, it is made it is any modification, equally replace It changes, improve, should all be included in the protection scope of the present invention.The scope of the present invention is defined by the appended claims.
