Afforestation is greatly developed in the attention of environmental problem, adaptation to local conditions is protected farmland, increase and decrease is linked up with, withdraws to land reclamation utilizes
Construction.
It withdraws to soil and refers to house site and its attached land used after removing discarded house, especially in some High aititudes
Area, mountainous region is more, and the house of resident is mostly built in greatly on the level land of hillside half way up the mountain, not only dangerous, but also destroys vegetation, present state
Family establishes centralized residential district, after resident moves down the unified inhabitation in mountain, a large amount of soils needs of withdrawing to is left on hillside and are cultivated and utilized again,
Plant revegetation ecology.
It is all slope above and below house, slopes are not since the house on hillside is mostly on the level land for be located at half way up the mountain
Surely, water loss is serious, along with the growth of the higher script plant of height above sea level is just more not easy, ultraviolet light is strong, day and night temperature is big,
Dry and wind-force is powerful, and become the to be covered with vegetation forest difficulty with withdrawing to that these are left is quite big, relies solely on
If the recovery capability of its own, long period, recovery effects are poor.
Summary of the invention
Present invention aims at solve existing method in the prior art to withdraw to land not for high altitude localities
Applicable problem provides high altitude localities and withdraws to soil vegetation repair method, passes through leguminous plant and pinus sylvestris var. mongolica and/or thorn
The plantation of Chinese scholartree, component one has certain ecological complexity composite ecological group, so that the speed for withdrawing to Land Succession is aobvious
It writes and accelerates, the trend for forming forest is more obvious, and the distribution density of the quickening of succession speed, root system persistently increases, and is conducive to
The reinforcement of slope stability in finite time shortens the time cycle for withdrawing to that land evolution is vegetation.
The present invention is achieved through the following technical solutions: land vegetation recovery method is withdrawn in high altitude localities, including walks as follows
It is rapid:
Constitute platform Step 1: withdrawing to soil surface and carrying out grading, gutter be set in platform two sides, on platform setting and
The setting pot that gutter is connected, reservoir is arranged in slope and platform junction above；
Step 2: covering the soil moved in improve the original of 30~50cm in platform surface；
Step 3: preparing several ecology bags, soil moved in improve the original is filled in ecology bag；
Step 4: the ecology bag is carried out the arrangement of " product " font along platform by anchor pole, in the region that ecology bag surrounds
It is interior to fill the concrete mix being mixed by soil moved in improve the original, low alkalinity cement, water-retaining agent, seeds of leguminous plant and water；It is wherein each
The weight ratio of component is soil moved in improve the original: low alkalinity cement: water-retaining agent: seeds of leguminous plant: water=50:3:2:1:40；
Step 5: excavating planting groove on the platform, and the filling planting matrix in planting groove；
Step 6: planting pinus sylvestris var. mongolica and/or locust tree in the planting groove.
Inventor devises this method for recovering vegetation by analysis, puts down first to the soil progress grading composition of withdrawing to left
The protrusions such as the house sidings left on these soils are bulldozed by platform, are on the one hand conducive to the growth of later period plant, are on the other hand
Weaken its destructive power of appearance landslide also greatly；Due to the soil serious water shortage in these areas, but the growth of vegetation
It is be unable to do without moisture, so need to carry out artificial rainmaking, but for the waste of water resource, so again the two of platform in this method
Side is provided with gutter, carries out water conservancy diversion to moisture extra during artificial rainmaking；It is found by the on-the-spot investigation of inventor, this
For the soil in a little areas due to the influence of weather conditions and soil erosion, the soil in these areas is mostly sandy soil, and viscous stickiness is low, manually
A large amount of silt can be adulterated after rainfall in extra moisture, so inventor is provided with settling pit on platform, to from row again
Silt in ditch is precipitated, to prevent the capacity of reservoir from becoming smaller；Since the soil in these places is mostly barrenr,
It carries out planting this directly on primary soil being very unpractical, so covering with new soil has been carried out to platform in step 2,
But since the soil moved in improve the original in covering in a short period of time cannot well and ontology soil is compatible, and these areas and frequent
High wind is had, in order to guarantee that the soil moved in improve the original of covering is not blown away, so inventor has prepared several ecology bags again in this method, and
It is also filled with soil moved in improve the original in ecology bag, is covered by soil moved in improve the original of the ecology bag to ramped surfaces, in the vpg connection of ecology bag,
By constructing model, last inventor has selected " product " font, will one monolith of script because passing through the arrangement mode of " product " font
Platform be divided into several junior units surrounded by ecology bag four sides, when encountering strong wind weather, this each junior unit week
The ecology bag enclosed just provides paravent for these junior units；The displacement of ecology bag in order to prevent simultaneously, solid in this method
Determine to be fixed when ecology bag using anchor pole, to improve the stability of ecology bag in use；In order to which component is suitable
Phytobiocoenose, selecting which kind of plant as the exploiting species of revegetation in this method is a very careful problem, is needed
It is considered in conjunction with the soil environment of discarded ground side slope, so inventor carries out the soil of withdrawing to that the multiple High aititudes in China are left
Soil sample, and soil is analyzed, it is compared with normal soil, inventor thinks that these Soils In The Regions are planted
The important restriction factor being resumed first is that soil nutrient is insufficient, and the extreme deficiency of N element is that core in nutrient deficiency is asked
Topic, so inventor has finally chosen the leguminous plant for capableing of fixed nitrogen as exploiting species, reason is specific as follows: because for first
The growth of cutting edge of a knife or a sword kind, it is mainly grown on soil moved in improve the original first, so the planting soil condition of leguminous plant substantially can satisfy
's；Exploiting species grow the initial stage for belonging to revegetation, and relevant staff can carry out human attendance to it, so it is given birth to
Length is that there is no problem, and again, the growth of exploiting species has to that soil nutrient structure can be improved, and supplements the N element in soil,
Which woods window invasive species last exploiting species will be suitable for；Based on above-mentioned several aspects, inventor has selected leguminous plant: the first,
Leguminous plant belongs to nitrogen-fixing plants, and some researches show that leguminous plant every 1hm every year2It can 50~150kg of fixed nitrogen；The second, perennial
The entire withered plant of the dry branches and fallen leaves of leguminous plant and annual leguminous plant after the season of growth can be to mention discardedly
For a large amount of organic substance, and the C/N content in this kind of organic substance is higher, to can effectively increase soil after disassembly
In N element accumulation；Third, leguminous plant can provide additional N element during the growth process for the growth of other plant, in addition
Leguminous plant can also promote the growth of the pinus sylvestris var. mongolica and locust tree in step 6 during the growth process, to keep these pioneer trees preferable
Construction one so-called " forest land environment ", make it more appropriate to those woods window invasive species.In the plantation means side of leguminous plant
Face, the destruction of leguminous plant soil for growth is used soil moved in improve the original, low alkalinity cement, water-retaining agent, beans by strong wind in order to prevent in this method
The concrete mix that plant seeds and water are mixed ensure that the viscous stickiness between leguminous plant growth soil, improve
The wind resistance of growing environment；In order to construct the phytobiocoenose with certain ecological diversity in this method, so inventor exists again
Excavated planting groove, while the filling planting matrix in planting groove on platform, planting matrix include Nutrition Soil, organic microbial,
Natural soil etc.；On the one hand the filling of planting matrix provides suitable growing environment, another party for the growth of pinus sylvestris var. mongolica and locust tree
The roach around diffusion couple that face passes through organic microbial carries out soil improvement；In terms of the selection of plant, it is contemplated that height above sea level and
The influence of weather, so different arbors is infeasible, so inventor has selected pinus sylvestris var. mongolica and locust tree herein, they are all
With good cold resistance and heat resistance, and due to high altitude localities sunlight on daytime irradiation time length and infrared ray and ultraviolet light
It is all relatively strong, and precipitation is less, so if if big blade arbor is planted in this place, it is easy to occur burning leaf phenomenon, and
The blade of pinus sylvestris var. mongolica and locust tree is all smaller, on the one hand prevents the generation for burning leaf phenomenon, on the other hand also helps reduction blade
Rising dehydration.By the plantation of leguminous plant and pinus sylvestris var. mongolica and/or locust tree, component one has certain ecological complexity multiple
Mould assembly ecological community, so that the speed for withdrawing to Land Succession is dramatically speeded up, the trend for forming forest is more obvious, succession speed
Quickening, the distribution density of root system persistently increases in platform, shortens the time cycle for withdrawing to that land evolution is vegetation.
Further, in the step 4 after fill concrete mixture, in concrete surface overlay film again.Due to high sea
Rise sheer from level ground area day and night temperature it is very big, daytime, surface temperature was higher, so the moisture in concrete mix is easily caused to be steamed
Hair falls, but the sprouting of seeds of leguminous plant has certain requirement to moisture again, if so in initial planting moisture supply
Seeds of leguminous plant is easily caused to break down if deficiency, so seeds of leguminous plant necrosis in order to prevent, surfaceman need
It is repeatedly watered within one day, this provides for improved the human costs of recovering plant cover of mine；And night temperatures are lower, and be easy to cause
Seeds of leguminous plant activity reduces, and embryonic speed is slow；It is inventor contemplated regarding to the issue above in concrete mix
Surface coating, because heat on daytime mainly reaches ground in the form of radiation, the moisture in concrete mix is evaporated, and is become
Rise at vapor, but most vapor will liquefy to form small water droplet after encountering the film that its surface is covered, without
It is directly evaporated in air, these small water droplets can be flow back into again in mixed mud mixture again when to the dusk, be guaranteed
Moisture too fast will not be evaporated, in addition after overlay film, daytime visible light and black light can pass through membrane body, make to mix
The temperature of solidifying soil mixture, which rises, accumulates certain heat, and nocturnal temperature low one of the major reasons in high altitude localities are to be exactly
Because blow caused forced-convection heat transfer, and due in surrounding ground moisture content it is few, so whole specific heat capacity is smaller, lead to
It is a degree of to prevent forced-convection heat transfer after crossing overlay film, while again because the moisture of mixed mud mixture has obtained sufficiently
Report barrier, so its specific heat capacity is also big compared with the original soil in surrounding mine, so also having obtained to a certain degree in night heat losses
Control, ensure that the activity of seeds of leguminous plant.
Further, further include following steps between step 1 and step 2:
Step A, the first injected hole that several depth are 1.5m~4m is opened up on the slope；
Step B, the calcium oxide aqueous solution that concentration is 12%~20% is squeezed into the first injected hole by grouting pump.
Because this kind of soil of withdrawing to belongs to acid discarded ground mostly, to restore it into and conducive to vegetation growth just have to
The pH value of soil is adjusted, so having been opened up on the slope several before carrying out covering with new soil to platform in this method
A depth is the first injected hole of 1.5m~4m, and the calcium oxide aqueous solution that concentration is 12%~20% is squeezed into the by grouting pump
In one injected hole；The main component of the aqueous solution of calcium oxide is calcium hydroxide, can be neutralized to acid soil.
Further, further include furfural dregs in addition to soil moved in improve the original in the ecology bag in the step 3, mushroom residue, water-retaining agent, glue
Mixture and organic fertilizer, wherein the weight ratio of each component is soil moved in improve the original: furfural dregs: mushroom residue: water-retaining agent: adhesive: organic fertilizer=
50:8:7:1:6:1.Because the intensity of sunshine of high altitude localities is big, the moisture of soil moved in improve the original is easy to be evaporated in ecology bag,
The generation of the phenomenon is so inventor joined water-retaining agent and adhesive, again by soil moved in improve the original entirety while water conservation again in order to prevent
Change, reduces the gas porosity of soil moved in improve the original in ecology bag, further reduce the evaporation of moisture, the microorganism in furfural dregs and mushroom residue
Rich content can create favorable conditions for the growth of subsequent bio.
Further, the step 5 further includes palm fibre and tossa in addition to planting matrix, and wherein palm fibre Zhan is total
The 0.4%~0.9% of weight, tossa account for the 0.7%~1.2% of total weight.In order to improve the freeze proof of concrete batching system
Durability, inventor recognized by inspection information when the content of palm fibre and tossa is respectively 0.6% and 0.9%,
Has the effect of increasing significantly to the endurance of concrete mix, in addition to this plant fiber can also improve under one's name concrete and mix
With the retentiveness, water-retaining property, drying shrinkage of object etc..
Further, further include following steps between step 1 and step 2:
Step C, the second injected hole is opened up on the slope, the depth of second injected hole is 2m~6m；And institute
