Abstract
The utility model relates to a screen frame structure for restoring surface soil of degraded grassland in a desert steppe. The screen frame structure is of a tetragonal structure which is surrounded by four identical rectangular reticular parts (1) after the rectangular reticular parts (1) are supported through a support part (2) and is vertical to the ground, the size of the reticular parts (1) is 100cm*30cm, the size of grids of the reticular parts (1) is 14 meshes, and the final size of the screen frame structure is 100cm*100cm*30cm.
Description
Technical field:
The table soil that the utility model relates to the degeneration grassland reproduces and the technology for recovering vegetation field.
Background technology:
Desertification is as a kind of compound land deterioration process, is to cause that natural environment becomes bad, the ecosystem is unbalance, the key factor of restriction mankind's socio-economic development, first of the world today, the row position ten overall situation problems.The existing a lot of researchs of the recovery of deteriorate grassland at present divide two classes substantially, and a class is artificial recovery, such as introduce a fine variety after-culture, the fertilising etc. of reclaiming, another kind of is that nature recovers, such as sealing child care, ecological immigrant etc.These measures or method do not relate to higher cost, and strong artificial disturbance is carried out on the grassland, exactly herdsman's mode of production and life are had very large influence or change fully.Present technique is utilized the characteristics of the original vegetational type of desert steppe, and the characteristics of checking winds and fixing drifting sand of simulation caragana shrubbery are carried out the meadow of induction type and recovered.Combine artificial action and natural force, little to the interference of deteriorate grassland soil, the function of checking winds and fixing drifting sand of reservation artificial sand-break.Help vegetation recovery.
The utility model content
The utility model relates to deteriorate grassland table soil and reproduces and technology for recovering vegetation.
Especially, the purpose of this utility model provides and a kind ofly is used for that deteriorate grassland table soil reproduces and/or the screen frame structure of vegetation recovery, concrete, the tetragonal body structure perpendicular to ground that described screen frame structure surrounds after to be four identical rectangle mesh members 1 by support component 2 support is as the unit of checking winds and fixing drifting sand independently.
Especially, described mesh members 1 is of a size of 100cm x30cm, and the final size of screen frame structure is 100cm x100cm x30cm.
Especially, the size of mesh opening of described mesh members 1 is 14 orders.
Especially, described mesh members 1 is a nylon wire.
Especially, described support component 2 is reinforcing bar or hardwood rod.
Utilize screen frame structure described in the utility model can realize that deteriorate grassland table soil reproduces and vegetation recovery, method is, adopt the screen frame of certain size, press certain density fixed placement on deteriorate grassland, be used to keep out the wind, fix the sand, accumulation table soil is in conjunction with manpower and natural force, induce the pionner growth, thereby recover the grassland.This method is disturbed few, easy to operate to soil, simulate original vegetation characteristics, is beneficial to vegetation recovery.
Concrete method is that on the degeneration grassland of desert steppe, selection will be carried out the zone that recover on the meadow, aspect geographical conditions, must be to select the landform such as gentle slope of Plain and knob to be used as implementing the zone.With reference to the cover degree of the common scrub plant caragana of desert steppe before grassland degeneration, set the number of screen frame.Screen frame all is fixed on the deteriorate grassland, evenly distributes, and is separated by one meter between each screen frame to number Mi Yuan, forms the screen frame group who is made of independent screen frame.
Characteristics of the present utility model are: by described structure,, be fit to desert steppe weather and vegetation characteristics in conjunction with manpower and natural force, and little to the prairie soil interference, be difficult for causing further destruction; The ecological functions of the plant caragana of simulation desert steppe NATURAL DISTRIBUTION can be checked winds and fixed drifting sand, and reproduce deteriorate grassland table soil, help vegetation growth and recovery.
Description of drawings
Fig. 1 has shown a kind of embodiment of screen frame structure described in the utility model.
Fig. 2 has shown and uses screen frame structure described in the utility model to realize that chart reproduces, shows that soil reproduces, the workflow of vegetation recovery.
The specific embodiment
The making of screen frame: utilize nylon wire (14 order), the specification of pressing 100cm x100cm with 4 reinforcing bars or 4 hardwood rods, as support, surrounds square screen frame, and the high 30cm in edge is perpendicular to ground, as the unit of checking winds and fixing drifting sand independently.
Embodiment 2
Screen frame group's setting: on the degeneration grassland of desert steppe, selection will be carried out the zone that recover on the meadow, the cover degree data of caragana in the local vegetation before consulting document and degenerating perhaps by consulting document and field investigation, obtain the do not degenerate caragana cover degree data in area of adjacent meadow.
According to these cover degree data, be unit with per what screen frames of 100 square meters, set the number of screen frame.Concrete grammar is, according to document or survey data, when cover degree 〉=6%, 6 screen frames is set; When cover degree＜6%, be the screen frame number with its cover degree value.(if by related software calculate＜6% cover degree data, fractional part can be rounded up, be the screen frame number with its integer part then)
Screen frame all is fixed in ground, makes every effort to even distribution in set ground sheet, forms by the screen frame group.Screen frame group's size is adjusted with the ground sheet size that will recover.
Grassland research institute, China Agriculture academy of sciences has carried out relevant grassland at Inner Mongolia Autonomous Region Xilinguole League Sunite Right Banner desert steppe deteriorate grassland and has resumed work.Restoration result is used the trial zone biomass of screen frame, and the trial zone biomass than not using the screen frame measure has on average increased by 12.68%.After snowing winter,, use the trial zone of screen frame measure through the effect of wind-force, accumulated snow thickness 25cm, and the trial zone accumulated snow thickness that screen frame is not set is less than 5cm.
Claims (3)
1. the screen frame structure that soil recovers is shown on a desert steppe degeneration grassland, it is characterized in that described screen frame structure is the tetragonal body structure perpendicular to ground that surrounds after four identical rectangle mesh members (1) support by support component (2), described mesh members (1) is of a size of 100cm x30cm, the size of mesh opening of described mesh members (1) is 14 orders, and the final size of screen frame structure is 100cm x100cm x30cm.
2. according to the screen frame structure of claim 1, wherein said mesh members (1) is a nylon wire.
3. according to the screen frame structure of claim 1 or 2, wherein said support component (2) is reinforcing bar or hardwood rod.
