Abstract

The invention discloses a desertification control method by soil, which belongs to the field of ecological environment protection. The invention solves the technical problem of restoring vegetation in a plateau cold area with the elevation of 4,000m or so. Particularly, the road yarn technology removes the restriction bottleneck that a rubber tyre wheel car can not convey soil on sand so that the problem of mechanical and scale construction of a desertification area is easily solved. The method can restore the ecology in the upper reaches of the Yellow River, and specially, the grassland desertification of a Maqu region and a Ruo region which are called a Yellow River reservoir is expected to be thoroughly controlled. The method comprises the following construction steps of: 1. knitting road yarn; 2. flattening a desert area; 3. preparing soil; 4. conveying the soil; 5. paving the road yarn; 6. unloading the soil; 7. spreading the soil; 8. coiling the road yarn; 9. sealing by a fence; and 10. sowing grass seeds.

Description

Soil covering desertification control method

The present invention relates to the ecological environmental protection field.If it is to administer Maqu County, Gansu Province, Ruoergai country, Sichuan Province＜hereinafter to be referred as the agate area in research〉Grassland Desertification in, go through the desertification control method of summing up after the repeatedly failure out.

People defended tenaciously the mindset of " three Norths " regional sand control in the past, if the regional sand damage of agate is administered in the measure of kind of a grass, tree planting, water caltrop lattice of indiscriminately imitating.Practice proves atrociously: if these measures are at all unworkable in the agate area! Must change thinking, look for another way.If the regional rainfall of agate is more abundant, loess resource is abundant near the sand damage district.Purpose of the present invention is exactly for the special natural conditions in this area, with the husky method of earthing lid, thoroughly shuts drift sand, then fence-enclosing, Second Year earthing after the sunization, are sowed good grass seed naturally, from the 3rd year, recover successively vegetation, the final radical cure sand damage that realizes.

Implement the present invention, operating procedure is as follows:

1. make the road yarn: be woven into widely 4.5 meters with finer wire, long 100 meters road yarn twists in and is equipped with on the axle that steel ball can freely rotate, and then axle is installed on the crawler type volume charka;

2. smooth sand damage district: substantially push away husky slope, the dell of " horse spine " formula flat with bulldozer;

3. standby soil: select soil layer abundant, without sandstone and the mixed Tu Yuan that gives birth to of rock (peel off deposit until rear recovery surface vegetation), then with the excavator pine, pulverize, in heaps, in order to loading and transporting;

4. muck haulage: the soil that will dig with loading machine is packed in the side turn over dump truck, transports the sand control district to;

5. lay the road yarn: during sand control, crawler type volume charka drives the sand damage district into, and the road yarn is spread out, and is current for the glue tire wheel automobile of muck haulage as " track ";

6. unload soil: the road yarn of muck haulage car by completing, soil is discharged at a side successively, then the road yarn is withdrawed from reversing;

7. the stand is native: manually soil is spread out (design thickness is 4-6 centimetre);

8. roll up the road yarn: when unloading soil to the road yarn end, crawler type volume charka is rolled the road yarn, from the beginning sets up another one time;

9. fence-enclosing: after the ground earthing that desertifies is complete, with the chain link fence sealing, damage in case livestock enters rear trample at once;

10. sow grass seeds: the native First Year of covering does not grow grass, and Second Year is through nature sunization, resists cold by manually sowing preferably, the grass seeds of well developed root system, recovers successively vegetation from the 3rd year.

The present invention compared with prior art has the following advantages:

1. if soil can be resisted the regional severe cold of agate.Existing sand control technology is directly to plant grass, tree planting etc. at sand, these technology are feasible in " three Norths " area, and if own through repeatedly proving failure in the practice of agate area.Because height above sea level is up to 3500-3800 rice here, high height above sea level has determined low temperature, and " belong to continental high and cold humid region, obvious plateau here, high and cold and rainy (snow) without dividing of the four seasons, only has changes in temperature not.Cold season reaches 314 days, and is very long and cold.Warm season 51 days, of short duration and gentle "." without absolute frost-free season, average temperature of the whole year 1.2 degree, growing season of grass 190 days " (seeing " Maqu County overview " www.xinhuanet.com Gansu channel).Husky earth because of particle is thick, inviscid, the gap large, easily ventilative, be not incubated, cause plant unablely to resist severe cold and die young in the growth of seedling phase of taking root.Soil is then opposite, because its particle is small, is rich in viscosity, and gas permeability is poor, and good heat preservation performance is suitable for plant to resist severe cold in the seedling phase of taking root.

2. soil can provide sufficient nutrient for plant growth.As previously mentioned, husky earth is unsuitable for water moisture self restraint because of the characteristics that its particle is thick, inviscid, the gap is large, is not suitable for microorganism existence, causes in the sand nutrition barren, and moisture evaporation is fast, and plant was died young because of the nutrition inadequate natural endowment in the seedling phase of taking root.Soil is then opposite, because its particle is small, is rich in viscosity, is suitable for water moisture self restraint, and suitable microorganism existence can provide sufficient nutrient for plant.

3. soil can be resisted the erosion of wind.Maqu County government once copied the method in " three Norths " area for administering sand damage, organized local herdsman at the ground water caltrop lattice that desertify, but winter in the past not also, not only husky incurable live, and careless lattice are buried changed beyond recognitionly by sand on the contrary, have no the sand control effect.Not that the careless lattice pricked of herdsman are defective, if but the result that the constant dry monsoon in agate area is wreaked havoc.Although dry monsoon only has about the 4-5 level, people and animals are not constituted direct threat, but be enough to make sand drift moving indefinite, towards Dong Xixi, cause the fixedly shaping of sand ground top layer, make plant can not get a stable living environment, even if the root that the plant that survives also often is etched is exposed, freeze hungry body dead.By contrast, soil then can be resisted the erosion of wind, and the plant that takes root the phase for seedling provides a stable living environment, avoids the evil of exposing.In a word, soil is the natural paradise of plant growth, has soil just grass can be arranged, and just energy vegetationization of grass is arranged.This is the masterpiece of the Nature, is objective law independent of man's will.Soil covering desertification control method has been complied with this rule.

4. soil covering desertification control can make " yellow-evil " thoroughly disappearance, and the district that realizes desertifying is by the green mankind's dream of xanthochromia.Up to now, other desertification control methods can only accomplish that the people advances sand and moves back, and move back and without cease, and soil covering desertification control can make the yellow-evil disappearance.As long as accomplish permanent fence-enclosing after covering the sand damage district, the Nature will make the earth's surface of administering the district green by xanthochromia.

5. economically feasible.If regional to herd as owner's agate, tree planting must be shipped seeds from the other places, the water caltrop lattice must ship hay from the other places, and cost is very high.And soil covering desertification control method is gathered materials on the spot, and is inexhaustible, and cost is low, economically feasible.

6. technical feasible.Earthing has solved the problem of natural vegetation restoration, and road yarn technology is that track has been laid in the muck haulage on sand of glue tire wheel automobile, makes sand control engineering be able to mechanization, appropriate scale of operation, can make improvement speed high-speed cruising.
