Abstract
This invention provides a control sand method which uses sand fence. This method is to bury the wheat grass or the branch in the desert to form many rectangle cavities, then use the sand to bury the wheat grass or the branch to form the sand fence which is above the desert surface at least 10 cm. After that use the chemical sand-binding substance to form the solidification layer which is at least 5 mm high on inner, outer or bottom of the sand fence, it will form the sand fence and plant psammophyte in the center of rectangle cavities. This method defends sand and cures sand over a long period.
Description
Technical field:
The present invention and suitable desert particularly annual precipitation are lower than the sand fence sand governing method that engineering sand control, chemical sand control, controlling sediment by plant method dexterously combined of 300mm in the desert of drought.
Background technology:
China is subjected to one of the most serious country of desertification harm in the world.267.4 ten thousand square kilometres in existing desertification soil accounts for 27.3% of territory total area, and with annual 30000 square kilometres speed increase.The annual economic loss that causes because of desertification is up to 54,000,000,000 RMB.For a long time, the Party Central Committee, State Council attach great importance to the protection and the construction of China's ecological environment.Advocate down in government, through people from all walks of life's joint efforts, China's control of desert work obtains certain progress, but effect is obvious inadequately, still is in the state of " local improvement, the whole deterioration " at present.Its reason is that China has a large amount of drought deserts, because precipitation very little, is difficult to large tracts of land utilization vegetative sand control.The improvement in these deserts is still continued to use the classical way of the embedding straw checkerboard barrier of the scientist of Russia Dinko Petrov invention in 1845.Owing in the abominable natural environment in desert, rise and reduce wind speed, stop the wheat straw life-span of flowing in the desert to have only 2～3 years, if untimely renewal, straw checkerboard barrier has also just lost sand prevention, sand fixation.Area with embedding straw checkerboard barrier sand control is bigger like this, the annual area that needs to upgrade is also healed big, in case newly-increased straw checkerboard barrier fixes the sand area and is lower than and needs regeneration area, will produce the situation of " local administer, whole worsen ", that is to say that colored great amount of manpower and material resources and financial resources can not receive the effect of basic improvement.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, a kind of long-term sand prevention, the effective sand fence sand governing method of sand control are provided.
The object of the present invention is achieved like this:
Sand fence sand governing method of the present invention; this method is that wheat straw and/or branch are embedded in a large amount of rectangular cavity of formation in the desert; again with husky wheat straw and/or branch are buried to form exceed the desert floor husky fence body of 10cm at least; then with chemical sand-fixing materials with in the husky fence body; external surface and bottom periphery solidify to form the cured layer that thickness is at least 5mm; thereby form husky fence; rectangular cavity center plantation psammophytes; the chemical sand-fixing materials buyable is that also can to adopt the applicant be 200410022520.9 chemical sand-fixing materials in the application number of application in 2004 to the chemical sand-fixing materials of Main Ingredients and Appearance with silicate; wheat straw and/or branch play in husky fence and stop sand drift moving and be convenient to form husky fence and the husky fence rupture strength of increase; increase of the effect of husky fence to the resist ability of wind-force; be engineering sand control; the chemosetting layer has played the protection wheat straw and/or branch is not influenced by heavy weather; make its without putrefaction and increase the resist ability of husky fence, be chemical sand-fixing the wind erosion.The rectangular cavity center can form permanent vegetative sand control layer owing to there is the protection of husky fence to help the growth of artificial or spontaneous growth plant, is vegetative sand control.
The height of above-mentioned husky fence is 10～20cm, and width is 20～40cm.
Cured layer thickness on the above-mentioned husky fence is 5～10mm.
The cross sectional shape of above-mentioned rectangular cavity is square, and the length of side is 1～2m.
Adopt wheat straw and/or branch in the husky fence can reduce wind speed, stop sand drift moving in the inventive method; because husky fence center has wheat straw and/or branch to resist wind-force as skeleton; there is chemosetting layer protection center framework not to be subjected to the influence of harsh weather and the eolian erosion of wind outward; again because the husky fence integral rigidity after solidifying is good; can also reduce the stressed of skeleton, therefore the life-span of husky fence is more much longer than the wheat straw life-span of the careless fence in the prior art.Because the protection of husky fence is arranged, the center of rectangular cavity more helps the growth of artificial or natural plants.Under the long-term protection of husky fence, the permanent vegetative sand control layer of the very easy formation in the center of rectangular cavity, so when husky fence lost efficacy, the effect that the vegetative sand control layer has played control again, fixed the sand, the purpose of can reach long-term sand prevention, fixing the sand.
The inventive method integrates that engineering is fixed the sand, chemical sand-fixing and vegetative sand control, so long-term sand prevention, sand-fixing effect are good.
Description of drawings:
Fig. 1 is the husky fence floor map of rectangular cavity.
Fig. 2 is husky Fence structure schematic diagram.
The specific embodiment:
Embodiment 1:
Fig. 1, Fig. 2 have provided present embodiment 1 husky Fence structure schematic diagram.Present embodiment 1 method is wheat straw and/or branch 1 to be embedded in a large amount of length of side of formation is the rectangular cavity 2 of 2m in the desert.With sand wheat straw and/or branch are buried the husky fence body 3 that forms 10cm above ground level, use the chemical sand-fixing materials (the also chemical sand-fixing materials that can adopt the applicant to apply for) of outsourcing then to solidify to form thickness be thus that the chemosetting layer 4 of 5mm forms highly is that 10.5cm, width are the husky fence 5 of 30cm with the inside and outside surface of husky fence body and bottom periphery.Husky fence rectangular cavity center plantation psammophytes 6.
The foregoing description is that foregoing of the present invention is further described, but this should be interpreted as that the scope of the above-mentioned theme of the present invention only limits to the foregoing description.All technology that realizes based on foregoing all belong to scope of the present invention.
Claims (5)
