Abstract
The present invention provides a kind of administering methods of Rocky Desertification.On the one hand the present invention is used directly for Rocky Desertification Region water and soil conservation in such a way that geotextile and geotechnical grid are used in combination, create conditions for large area afforestation, vegetation is on the other hand planted in geotechnical grid, rebuild the ecosystem；Consolidate stone water conservation from root, prevents the extension of stony desertification.The present invention, which implements once administer Rocky Desertification Region, plays effect well, can effectively accomplish water and soil conservation, be effectively improved the condition needed for vegetation and shelter-forest growth, efficiently use the wide stony desert resource in China, saved stony desertification land cost.
Description
Technical field
The present invention relates to Rocky Desertification Control and stony desertification ecosystem rehancement field of engineering technology, especially a kind of soil stone
The administering method of desertization.
Background technology
Stony desertification（Stony Desertification）Refer in the torrid zone, subtropical zone moistening, grassland climate condition and rock
Under the molten natural background extremely developed, is interfered by human activity, surface vegetation is made to wreck, soil is caused seriously to be lost in, base
Rock large area is exposed or the land deterioration phenomenon of gravel buildup and the extreme form of karst area land deterioration.To last century
End, in 740,000 sq-km enumeration district of Southwestern China Karst Areass, stony desertification area accounts for investigation up to 10.5 ten thousand sq-kms
The 14.2% of area's area, wherein slight stony desertification area is 4.0 ten thousand sq-kms, and moderate stony desertification area is 3.9 ten thousand square thousand
Rice, severe stony desertification area are 2.6 ten thousand sq-kms.Stony desertification occurs mainly in three provinces and regions of Yunnan, Guizhou and Guangxi, the gross area
For 8.8 ten thousand sq-kms, wherein the stony desertification area in Guizhou Province is 3.3 ten thousand sq-kms, and the stony desertification area in Yunnan Province is
The stony desertification area of 2.8 ten thousand sq-kms, Guangxi Zhuang Autonomous Region is 2.7 ten thousand sq-kms.Karst area Southwest China stony desertification face
Increase by 1650 sq-kms, annual growth 2% for many years.
Stony desertification is the ecological problem of China karst area most serious, is referred to as " cancer of the earth ".Stony desertification is mainly sent out
It is raw that in karst area, its origin cause of formation is extremely complex, existing natural cause, including：The batholith of karst area is that carbonate is easily made
At soil erosion, karst area precipitation is concentrated and intensity greatly soil erosion provides condition etc..More there are social factor, including mistake
Degree firewood gathering firewood material overgrazes, unordered industrial and mineral Development control area etc..The harm of stony desertification is very big, is mainly manifested in it directly
Cause land carrying capacity to be greatly lowered or even lose, aggravated natural calamity, seriously affected ecological safety, leads to stony desertification
Regional poor aggravation influences the sustainable development of economic society, stony desertification can cause vegetation structure to simplify, the ecosystem is simple
Change, bio-diversity is caused to fall sharply.Therefore the improvement of stony desertification is extremely urgent.
Invention content
The purpose of the present invention is：A kind of administering method of Rocky Desertification is provided, it is used directly for Rocky Desertification Region
Water and soil conservation creates conditions for large area afforestation, and rebuilds the ecosystem, prevents the extension of stony desertification.
The invention is realized in this way：The administering method of Rocky Desertification, pre-fill last layer is containing guarantor on stony desertification basal plane
The bottom soil horizon of aqua spreads geotextile on the bottom soil horizon, filled out on geotextile layer overlay contain water-retaining agent and
The soil of nutritional agents after overcompaction, then spreads geotechnical grid on the soil, the plant containing drought resisting is sprayed in geotechnical grid
The soil or transplanting rock vegetation of species.
The geotextile is that one or more of polypropylene fibre, terylene, polyamide fibre, polyethylene fibre or biodegradable fiber are former
Synthetic staple fibers needling nonwoven geotextiles, filament spunbond needling non-woven geotextiles, fabric hot rolled nonwoven fabrics or the degradable soil that material makes
Work cloth.
The water-retaining agent includes polyacrylamide, Sodium Polyacrylate, polyacrylic acid potassium, ammonium polyacrylate, starch-grafted
Acrylates crosslinking copolymerization object one of which or several.
The geotechnical grid is welding geotechnical grid, Grafting type earth lattice or riveting geogrid.
The geotechnical grid is perforation or non-porous geotechnical grid.
The height of the geotechnical grid is 5-50cm.
It is 1-50cm that the soil containing water-retaining agent and nutritional agents, which fills out paving thickness,；The wherein degree of water-retaining agent
For 0.1-20%；The degree of nutritional agents is 0.01-10%.
The filled slope of the bottom soil horizon is 1-50cm, and wherein the degree of water-retaining agent is 0.1-20%.
As a result of above technical scheme, the present invention in such a way that geotextile and geotechnical grid are used in combination,
On the one hand it is used directly for Rocky Desertification Region water and soil conservation, created conditions for large area afforestation, on the other hand in geotechnique
Vegetation is planted in cell compartment, rebuilds the ecosystem；Consolidate stone water conservation from root, prevents the extension of stony desertification.The present invention is implemented once i.e.
Rocky Desertification Region can be administered and play effect well, can effectively accomplish water and soil conservation, be effectively improved vegetation and shelter-forest life
Long required condition, efficiently uses the wide stony desert resource in China, has saved stony desert land cost.The present invention is simply easy
Row, of low cost, using effect is good.
Specific implementation mode
The embodiment of the present invention：The administering method of Rocky Desertification, in the Area of Southeast Guizhou of 2 months Guizhou in 2014 Experimental Base
It is upper to be tested as follows：
1）Stony desertification gravel basal plane is smooth, bottom soil horizon of the pre-fill last layer containing water-retaining agent, bottom on stony desertification basal plane
The filled slope of soil horizon is 20cm, and wherein the degree of water-retaining agent is 5%；
2）Geotextile is spread on the bottom soil horizon, the short fine needle that the geotextile used is made using terylene as raw material
Non-woven geotextiles；
3）The soil that layer overlay contains water-retaining agent and nutritional agents is filled out on geotextile, containing water-retaining agent and nutritional agents
It is 20cm that soil, which fills out paving thickness,；Wherein the degree of water-retaining agent is 3 %；The degree of nutritional agents is 0.1 %；And
It is compacted into；
4）Geotechnical grid is spread on the soil again, the soil of the vegetable seeds containing drought resisting is sprayed in geotechnical grid simultaneously
Carry out spray water；Used geotechnical grid is the riveting geogrid of perforation, height 30cm.
It is observed after in October, 2014, this area plant grows fine, and does not occur leading to Plant death because water shortage lacks nutrition
And the phenomenon that plant accumulated growth, this method administer stony desertification, root system of plant is more flourishing, can be secured entirely in soil.
The embodiment of the present invention being not limited to described in specific implementation mode, those skilled in the art are according to the present invention
Technical solution obtain other embodiments, also belong to the scope of the technical innovation of the present invention.Obvious those skilled in the art
Various changes and modifications can be made to the invention by member without departing from the spirit and scope of the present invention.If in this way, the present invention
These modifications and variations belong within the scope of the claims in the present invention and its equivalent technologies, then the present invention is also intended to comprising these changes
Including modification.
