A mobile sand dune control method

Abstract

The invention discloses a travelling dune control method which is characterized by comprising the following steps that an underground reservoir is established according to design; dunes are flattened with a bulldozer; the flattened dunes are compacted by a slab type rammer compactor and then act as sites; the sites are flattened by a road pressing machine; the flattened sites are covered; and various factories are constructed on the covered sites, and roads and green forest belts are constructed according to planning. The cover sites are covered with reinforced concrete precast slabs, the adjacent reinforced concrete precast slabs are hinged mutually, rainwater perforated strainers are arranged at hinged parts, and the covered sites comprise road project sites, green planting project sites and enterprise construction project sites. The travelling dune control method has the benefits that a clean power generation device is mounted, the construction site area of urban factories is reduced effectively, the agricultural cultivation area is increased, enterprises having water, air or noise pollution are migrated, the influences to urban residents are reduced, the living quality of people is improved, and by using grid afforestation or plant cultivation, wind sand is obstructed, air is purified and the possibility of haze is reduced.

Description

technical field [0001] The invention belongs to the technical field of desert control and relates to a mobile sand dune control method. Background technique [0002] China is one of the countries that are severely endangered by desertification. The desert area is 1.308 million square kilometers, accounting for 13.6% of the country's land area. The main reason for its harm lies in the desertification effect of moving sand dunes on the land. At present, the area of ​​mobile sand dunes in my country reaches 370,000 square kilometers, accounting for 28.3% of the total desert area, and it is expanding year by year. According to 2011 data from the Desertification Prevention and Control Management Center of the State Forestry Administration, the rate of desertification in China is expanding by 2,460 square kilometers per year, which is equivalent to the area of ​​a county. The number of people affected by desertification in the country is 170 million, and desertification has seri...

Problems solved by technology

Although China has vigorously carried out desertification prevention and control work, it still presents a situation of "partial governance, overall deterioration, and the speed of governance cannot keep up with the speed of deterioration", and the phenomenon of "sand ingress and human retreat" has not yet been curbed
