The method is that first fixed sand or half-flowing sand area whose length is 5-6 kilometer and width is 5-6 kilometer is selected to be used as a square or a rectangle prevention area, the flowing main direction of blown sand is rightly selected according to natural law of each area, a blown sand resistance wall whose length is 5-6 kilometer and is made through a cement pile and a cement wall plate is horizontally intercepted and fixedly arranged on the flowing main direction of the blown sand, the distance between the cement piles is 3-4 meter, the height of exposed sand surface of the cement pile is 2.0-2.5meter, a cement pile is fixed on the 50mm of buried sandy land, the cement piles are connected by wire ropes, the cement wall plate is hung on the wire ropes between the cement piles, and other three surfaces use the cement pile and a wire netting to make a link fence whose length is 5-6 kilometer. Referring to the method, the area of the sand prevention, the sand fixation and the planting biology are further enlarged based on an original sand fixation boundary. The method has the effects that the method for sand prevention, sand fixation and planting biology in a desert area is capable of effectively preventing fixing sand, the method is suitable to popularize in large area, the cost is low, and the effect is lasting.
Description
Technical field
The invention belongs to the sand-prevention, sand-fixation and planting in desert area field of engineering technology, be specifically related to a kind of method of sand-prevention, sand-fixation and planting in desert area.
Background technology
Desertification is a great ecological environment problem.Desert of China and desertification land area are about 160.7 ten thousand square kilometres, account for 16.7% of area.Current China desertification land area is just with annual 2460 square kilometres speed expanded, and also has the trend that enlarges quickened.The measure that China takes aspect preventing and treating in desertification is a lot, can reduce following three aspects: sand consolidation with biologic, chemical sand-fixing, engineering is fixed the sand, various sand fixing technologies can effectively stop the expansion in desert in short-term, but As time goes on, have the influence of the various human factors and the natural law to cause new desertification, defending and controlling sand is a complicated system engineering, relates to ecology, fixes the sand many-sided problems such as structure design, economy, society.Therefore, defend and control sand and will obtain long effect, must at first formulate reasonably to defend and control sand and plant living structure design on above-mentioned basis of fixing the sand measure, integral layout, subregion are administered, and promote comprehensively long-term plan; Must take into account economic benefit, ecological benefits and social benefit, give birth under the prerequisite of structure design, give top priority to what is the most important at correct sand-prevention, sand-fixation and planting; Prevent, control, use combination, planning of science activities, suit measures to local conditions, easy first and difficult later, earlier big, the key breakthrough in little back, focus on actual effects, carry out the work of defending and controlling sand.
Summary of the invention
The present invention can effectively stop the expansion in desert in order to solve various sand fixing technologies in short-term, but As time goes on, there is the influence of the various human factors and the natural law to cause new desertification problem, defend and control sand and to obtain long effect, must formulation reasonably defend and control sand and plant living structure design; The comprehensive each side factor of the present invention, and proposed a kind of method of sand-prevention, sand-fixation and planting in desert area, can be permanently effective defend and control sand and large scale application.
Technical scheme of the present invention is: the method for sand-prevention, sand-fixation and planting in desert area of the present invention, this method is at first to select a block length 5-6 kilometer, the moving husky district of the fixedly sand of wide 5-6 kilometer or semi-fluid is square or rectangular control district, correctly select the mobile principal direction of dust storm according to the natural law of each department, laterally tackle the husky wall of choke that utilizes concrete stake and the long 5-6 kilometer of cement wall plate manufacturing with Dingan County's dress one side in the moving principal direction of the sand drift that facings the wind, between the concrete stake apart from 3-4 rice, concrete stake reveals the high 2.0-2.5 rice of Shamian Island, bury fixedly concrete stake of 50 centimetres of sand grounds, connect with wire rope between the concrete stake, cement wall plate is suspended on the wire rope between the concrete stake, all the other 3 netting fences that utilize concrete stake and the long 5-6 kilometer of wire gauze manufacturing stop humans and animals to destroy in going into to fix the sand structure.
Netting fence be by between the concrete stake apart from 3-4 rice, concrete stake reveals the high 2.0-2.5 rice of Shamian Island, buries fixedly concrete stake of 50 centimetres of sand grounds, connects with wire gauze between the concrete stake.
Secondly, in the sand prevention district, pile 40-50 centimetre wide with sand, high 30-40 centimetre semicircular body Leng bank forms long 2.0-2.5 rice, the grid of wide 2.0-2.5 rice, 4 suitable little saplings of 4 angles of grid top plantation, to make with the Leng bank and at first spray suitable grass seeds and nutrient in the grid,, guarantee that grass seeds germinates at last with the Leng bank with spilt grass seeds and sprayed chemical sand-fixing materials that water mixes above the nutrient layer again and form sky more than 0.8-1.5 centimetre and fix the sand layer, absorb moisture, fixedly sand flows.
Method according to above-mentioned sand-prevention, sand-fixation and planting in desert area forms 25-36 square kilometre of zone,. after treating that the growth of trees and grass seeds survives, give birth at the original large tracts of land sand-prevention, sand-fixation and planting that fixes the sand on the basis, border further with reference to same method, year after year, day by day, will form large-area oasis band, society brings benefit to the mankind.
Advantage of the present invention and effect: the method for a kind of sand-prevention, sand-fixation and planting in desert area of the present invention, effectively sand-prevention, sand-fixation and planting is given birth to, and is applicable to the large tracts of land popularization, and the low effect of cost is lasting.
