Abstract
The invention relates to a screen frame structure and a method for desert steppe degradation grassland surface soil recovery. The screen frame structure is a tetragonal structure vertical to the ground, the tetragonal structure is formed by surrounding four identical rectangular reticular components (1) after the four identical rectangular reticular components (1) are supported through support components (2). The method belongs to a method capable of realizing the surface soil reconstruction and/or vegetation recovery through combining the screen frame structure with local caragana coverage data.
Description
Technical field:
The table soil on grassland of the present invention relates to degenerate 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.
Summary of the invention
The present invention relates to deteriorate grassland table soil reproduces and technology for recovering vegetation.
Especially, first purpose of the present invention 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.
Second purpose of the present invention has been to provide a kind of and utilized the deteriorate grassland table soil that is used for of the present invention to reproduce with the screen frame structure of vegetation recovery and realize that deteriorate grassland table soil reproduces the method with vegetation recovery, particularly, 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.
More specifically, 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 invention are: in conjunction with manpower and natural force, be fit to desert steppe weather and vegetation characteristics, 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.
The accompanying drawing summary description
Accompanying drawing 1 has shown a kind of embodiment of screen frame structure of the present invention.
Accompanying drawing 2 has shown and uses screen frame structure of the present invention to realize that chart reproduces, shows that soil reproduces, the workflow of vegetation recovery.
The specific embodiment
Embodiment 1
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.
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 (6)
