Description
One, technical field
The present invention relates to a kind of methods that Sand Movement is reduced in desert areas, especially a kind of to utilize photovoltaic panel and plant of keeping out the wind
It is alternately arranged to form the ecological method that windbreak reduces desert flowing.
Two, technical background
Desert Sand Movement is the movement that the grains of sand are carried under one's arms in air motion, is the Dual-Phrase Distribution of Gas olid of a kind of " atmosphere+grains of sand ".
Wind can be simply interpreted as and blow husky mobile phenomenon.The essence of wind-driven sediment is drive of the Terrestrial soil particle by wind energy
It is dynamic, it is detached from original place table and moves, in the process of strange land accumulation.Wind-driven sediment often changes the form of earth's surface.In the work of wind
Under, soil or rock particles near route are blown off by wind as wind erosion phenomenon, the particle swept by wind enter in air-flow with
Wind moves together, and this capacity graduation has earth's surface, building, structures bigger than having bigger kinetic energy without husky air-flow
Wind erosion ability.When the movement of air-flow is affected by other factors, and wind speed and kinetic energy reduce, air-flow and the particle by carrying
Between be easy to separate, fallen by the soil particle of carrying in earth's surface, generate accumulation.The process of this wind erosion and accumulation,
It is constantly changing the form of earth's surface, the generations such as building, structures, plant, train facility wind erosion, abrasion, shock, sand are buried
Phenomena such as.
Desertification is the serious environmental problem faced on our times.The whole world is every 5~70,000 km every year2's
Soil becomes desertification land, there is nearly 100 countries and regions, threat of 8.5 hundred million populations by desertification.China is in the world
Most wide one of the country of desertification distribution area.China desert is mainly distributed on northwest, North of North China and West of The Northeast China, and desert is total
Area is including gobi and desertification land up to 168.9 ten thousand km2, the 17.6% of national total area is accounted for, wherein nefied accounts for
39.8%, gobi accounts for 38.2%, remaining is desertification land.The Takla Makan Desert, ancient capital Xi'an, Badain Jaran
Several big main deserts such as desert, the desert Teng Geli, carex meyeriana obstructed economy between some areas, part provinces and regions,
Cultural exchanges.In order to reduce gap economic between region, the economic construction in allround promotion China.Party and government new China at
After vertical, the concern to desert area desertification status is begun to, has put into a large amount of manpower, object in desert and Gobi Region
Power expands the experimental study work of desertification, achieves certain effect.But these are defended and controlled sand, measure all has one
Fixed shortcoming, some measures only use various sand-prevention engineering materials, place obstacles object or laying bed course, or build dike,
Ditch mechanically carries out interference control to intercept the measures such as drift sand；Some measures are according to the growth characteristics for vegetation of keeping out the wind, manufacture
Vegetation growth condition, a large amount of vegetation of keeping out the wind of plantation comes catch blowing sand erosion and desert flowing, as typical three Norths shelter-forest.It examines
Consider desertification phenomenon get worse, the growing to even greater heights of dust storm sand control demand, the extensive concern of ecological management theory etc., need one
The it is proposed of the new ecological control of desert scheme of kind.
Three, summary of the invention
For existing defend and control sand obvious drawback and deficiency existing for measure, Sand Movement is effectively reduced, with realizing desert
The scientific utilization of domain space is alternately arranged to form gear the object of the present invention is to provide a kind of using power generation photovoltaic panel and vegetation of keeping out the wind
Brattice, effective less Sand Movement, and then realize the pattern of desert and Gobi Region ecological management and ecological protection.
BROAD SUMMARY:

The status that regional dust storm is wreaked havoc and region is wide realizes the scientific utilization of desert regional space to reduce Sand Movement, proposes
Effective windbreak is formed in the way of power generation photovoltaic panel and vegetation alignment placement of keeping out the wind, photovoltaic panel is protected each other with vegetation, is produced
Raw corresponding electric energy and bioenergy, while increasing the vegetation cover degree of desert region, play the role of protecting environment.
2. the method that a kind of photovoltaic panel arrangement windbreak according to claim 1 reduces desert flowing, it is characterized in that:
Vegetation and the photovoltaic panel of keeping out the wind are interleaved alignment placement, in dust storm direction windward, be followed successively by vegetation of keeping out the wind, power generation photovoltaic panel,
Adaptive plant growing area, vegetation of keeping out the wind, electric discharge photovoltaic panel, are so alternately arranged, and form a kind of life for utilizing, protecting each other each other
State windbreak mode.
3. the method that a kind of photovoltaic panel arrangement windbreak according to claim 1 reduces desert flowing, it is characterized in that:
Windbreak spread parameter is determined according to Sand Movement intensity, and in direction windward, first barrier is total with photovoltaic panel for vegetation of keeping out the wind
With composition, width a is typically larger than 5m, wherein the plantation width a for the vegetation that guarantees to keep out the wind0Between 2m to 3m, vegetation of keeping out the wind plantation
Height h requires to be not less than 2m；It is adaptive plant growing area after first of paravent, plants adaptability according to local environmental conditions and plant
Object, wherein it is required that, adaptive plant plantation sector width b must not exceed 30m；Second barrier is laid out according to first barrier parameter,
Until entire desert Regional distribution is completed.
