Abstract
The present invention relates to net frame structure and the method for the recovery of a kind of desert steppe Degraded Pastures table soil, described net frame structure is four the identical tetragonal body structures perpendicular to ground of rectangle mesh members (1) by surrounding after support component (2) support.To be net frame structure realize showing soil in conjunction with the cover degree data of local caragana to described method reproduces and/or the method for vegetation recovery.
Description
Technical field:
The table soil that the present invention relates to Degraded Grasslands reproduces and technology for recovering vegetation field.
Background technology:
Desertification as a kind of compound land deterioration process, be cause natural environment become bad, the ecosystem is unbalance, restriction mankind's socio-economic development key factor, first of the Lie Wei world today ten overall situation problem.The recovery of current deteriorate grassland has a lot of research, basic point two classes, and a class is artificial recovery, and such as introduce a fine variety after-culture, reclaim and apply fertilizer, another kind of is clear-cutting forestland, such as seals child care, Ecological Immigration etc.These measures or method, do not relate to higher cost, and carry out strong artificial disturbance to grassland, has very large impact exactly or change completely herdsman's mode of production and life.This technology utilizes the feature of the original vegetational type of desert steppe, and the feature of checking winds and fixing drifting sand of simulation peashrub shrubland, carries out the range restoration of induction type.Combine artificial action and natural force, little to the interference of deteriorate grassland soil, retain the function of checking winds and fixing drifting sand of artificial sand-break.Be conducive to vegetation recovery.
Summary of the invention
The present invention relates to Degenerated ground surface soil to reproduce and technology for recovering vegetation.
Especially, first object of the present invention is to provide a kind of reproducing for Degenerated ground surface soil and/or the net frame structure of vegetation recovery, concrete, described net frame structure is four the identical tetragonal body structures perpendicular to ground of rectangle mesh members 1 by surrounding after support component 2 support, as the unit that independently checks winds and fixes drifting sand.
Especially, described mesh members 1 is of a size of 100cmx30cm, and the final size of net frame structure is 100cmx100cmx30cm.
Especially, the size of mesh opening of described mesh members 1 is 14 orders.
Especially, described mesh members 1 is nylon wire.
Especially, described support component 2 is reinforcing bar or hardwood rod.
Second object of the present invention there are provided and a kind ofly utilize of the present invention reproducing for Degenerated ground surface soil to realize Degenerated ground surface soil with the net frame structure of vegetation recovery and reproduce the method with vegetation recovery, particularly, adopt the screen frame of certain size, by certain density fixed placement on deteriorate grassland, for keeping out the wind, fixing the sand, accumulation table soil, in conjunction with manpower and natural force, the growth of induction pionner, thus recover grassland.This method is few, easy to operate to soil interference, simulates original vegetation characteristics, is beneficial to vegetation recovery.
More specifically, on the Degraded Pastures of desert steppe, selecting the region will carrying out range restoration, in geographical conditions, must be select the landform such as the gentle slope of Plain and knob to be used as implementing region.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 is all fixed on deteriorate grassland, is uniformly distributed, and is separated by one meter to number meter Yuan, forms the screen frame group be made up of independent screen frame between each screen frame.
Feature of the present invention is: in conjunction with manpower and natural force, is applicable to desert steppe weather and vegetation character, little to prairie soil interference, not easily causes further destruction; The ecological functions of the plant caragana of simulation desert steppe NATURAL DISTRIBUTION, can check winds and fix drifting sand, reproduce Degenerated ground surface soil, be conducive to vegetation growth and recovery.
Accompanying drawing summary description
Figure 1 shows a kind of embodiment of net frame structure of the present invention.
Figure 2 shows and use net frame structure of the present invention to realize chart to reproduce, show that soil reproduces, the workflow of vegetation recovery.
Detailed description of the invention
Embodiment 1
The making of screen frame: utilize nylon wire (14 order), by the specification of 100cmx100cm, with 4 reinforcing bars or 4 hardwood rods, as support, surrounds square screen frame, edge height 30cm, perpendicular to ground, as the unit that independently checks winds and fixes drifting sand.
Embodiment 2
The setting of screen frame group: on the Degraded Pastures of desert steppe, selection will carry out the region of range restoration, cover degree data of caragana in local vegetation before By consulting literatures obtains and degenerates, or by By consulting literatures and field investigation, obtain adjacent meadow and not to degenerate the caragana cover degree data in area.
According to these cover degree data, in units of every 100 square meters how many screen frames, the number of setting screen frame.Concrete grammar is, according to document or survey data, when cover degree >=6%, arranges 6 screen frames; As cover degree < 6%, with its cover degree value for screen frame number.(if the cover degree data of the < 6% calculated by related software, fractional part can be rounded up, then with its integer part for screen frame number)
Screen frame is all fixed on ground, makes every effort to be uniformly distributed, formed by screen frame group in set ground sheet.The size of screen frame group, adjusts with the ground sheet size that will recover.
The grassland instauration work that grassland research institute, China Agriculture academy of sciences is correlated with at Inner Mongolia Autonomous Region Xilinguole League Sunite Right Banner desert steppe deteriorate grassland.Restoration result, uses the trial zone biomass of screen frame, than the trial zone biomass not using screen frame measure, on average adds 12.68%.After snowing winter, through the effect of wind-force, use the trial zone of screen frame measure, Snow Thickness 25cm, and the trial zone Snow Thickness not arranging screen frame is less than 5cm.
Claims (5)
