Description
Technical field
The present invention relates to a kind of method of Desert Control, more particularly to a kind of desert soil structure and ecological environment of changing
Physico-chemical process.
Background technology
Control of desert is a world-famous puzzle, and China is that desert more than one is national, and the deep country by desert harm
One, at present, the desert area and desertification area in China are increasing, have reached 168.9 ten thousand square kilometres, have accounted for area
17.6%, interior basin between 35 degree to 56 degree of north latitude, plateau are mainly distributed on, forms one west from Tarim Basin,
West of Songnen Plain arrive in east, 4500 kilometers of thing length, the desert belt that wide about 600 kilometers of north and south, and with annual 2460 square kilometres
Speed expanded.
China increases the dynamics to control of desert in recent years, but the extension of desert and desertification still becomes in expansion
Gesture.
Plant or crops are difficult to have three the main reason for desert grows：When the missing of moisture, second, desert soil
Loose structure, necessary crumb structure in soil is lacked, third, movement and the mobility of desert soil subparticle, cause plant
Root system is difficult to take root.
The content of the invention
Technical problem solved by the invention is to be directed to existing desert and desertification ecological environment problem, proposes a kind of change
Existing desert and the physical method of desertification soil texture and ecological environment, this method have that speed is fast, the spy of construction is simple
Point, existing desert area Current Situation of Eco-environment can be improved rapidly.
The technical solution adopted by the present invention is：Change the physico-chemical process of desert soil structure and ecological environment, step
It is as follows：
1. the soil that needs are improved is carried out smooth；
2. compactness, infiltration coefficient and the water content in the soil before measure improvement；
3. the soil improved using dynamic compaction machinery to needs carries out full rammer, change the microcosmic knot of desert soil using strong rammer impact energy
Structure, desert soil can produce certain consolidation after strong rammer, improve compactness, form crumb structure, reduce vertically moving for moisture, make
Hydrone can be conserved in soil, add the humidity and water content of soil, and primary condition is created for the growth of plant；
4. grouting material of being sprayed on the soil after strong rammer, pipeline of the grouting material along desert, which flows down, to be oozed, and is being penetrated into
Under earth's surface during precalculated position, the rapid expansion curing of the grouting material, thus block the pipeline flow structure in desert；
5. compactness, infiltration coefficient and the water content of the soil after detection improvement, it is determined that the plant that can be planted.
The plant of described step 5. can be crops, or herbaceous plant or xylophyta.
The strong rammer step of described step 3. is：
A. dynamic compaction machinery is in place, and full rammer is carried out to whole place；
B. dynamic compaction machinery control system is adjusted, makes the hammer ram movement of falling object；
C. the potential energy of hammer ram is changed into kinetic energy, and its kinetic energy produces destruction to the soil texture in desert, so that desert
The structure of soil is changed.
The method of the water content of soil after the detection improvement of described step 5. is that the soil after improvement is seeped water
Experiment, measure water content simultaneously draw the relation curve of water content and time, before contrast improvement with improve after soil it is stable aqueous
The difference of amount, the plant or crop of suitable growth are selected according to the stable aqueous amount of soil after improvement.
4. described grouting material is high polymer material to step.
Described step 4. after soil surface spray fixative.
Described grouting material includes cement mortar.
According to the ratio of mud that described cement mortar is determined the time required to precalculated position is seeped under grouting material.
The ratio of mud of described cement mortar is 2-5.
The invention has the advantages that desert water and soil flowing water can be prevented effectively, Soil Microstructure is changed, is allowed the water to
Self-restraint is in the structure of soil.And under follow-up natural environment, the soil after natural precipitation can also be modified conserves, and is
Plant growth provides enough moisture, is effectively prevented soil erosion.
