Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
The utility model embodiment provides a kind of oasis protection system, as shown in Figure 1, comprising: from oasis periphery to green
The drift sand extended on the inside of continent consolidates stopband 2, check winds and fix drifting sand band 3 and protection forest net 4；The drift sand consolidates stopband 2 by wheat straw sand-protecting barrier and PLA
Sand-protecting barrier composition；The band 3 of checking winds and fixing drifting sand is the structure that shrub combines, and the protection forest net 4 is arranged with the interval of farmland 5.This is practical
It is novel to select acid fiber by polylactic (PLA) and wheat straw as main steady husky material, secondary pollution will not be caused to environment, constructed
The integrated protection system netted by two bands one that drift sand consolidates stopband, check winds and fix drifting sand band and protection forest net form, can reach good
The effect of checking the wind and fixing the shifting sand promotes integral protection benefit.
Preferably, as shown in Fig. 2, the drift sand consolidates the wheat straw sand-protecting barrier 21 of stopband 2 and PLA sand-protecting barrier 22 is grid-like staggeredly cloth
It sets, the size of grid-like the wheat straw sand-protecting barrier and PLA sand-protecting barrier is 1.5m*1.5m；The vegetation for checking winds and fixing drifting sand band 3 includes white
Thorn, sand sagebrush (Artemisia filifolia), sacsaoul and Sha meter；The tree species of the protection forest net 4 include Xinjiang poplar, arrow-leaved oleaster and elm.
In a specific embodiment of the utility model, along prevailing wind direction vertical runs oasis protection system, including use
The drift sand of 1.5m*1.5m mixing sand-protecting barrier composition consolidate stopband, and sand-protecting barrier material is wheat straw and acid fiber by polylactic (PLA), and by it is white pierce,
The shrub wind prevention and sand resistance band of sand sagebrush (Artemisia filifolia) composition.Southwester depth 500m sand-protecting barrier area is that oasis periphery drift sand consolidates stopband in northeast.Shrub is anti-
Windage sand combination bandwidth is 300 meters.Wherein, 1.5m*1.5m mixing sand-protecting barrier be made by acid fiber by polylactic (PLA) fabric it is flat
Paving formula grid sand-protecting barrier replaces laying with wheat straw grid sand-protecting barrier.Acid fiber by polylactic (PLA) fabric fills sand, reaches nature saturation shape
State is laid in naked husky upper sandy soil, and the height of flush system sand-protecting barrier is the diameter of long cylinder under nature saturation state at this time, and diameter is about
20cm is laid with according to format collocation method.
The utility model has the following effects that and advantage:
The first, protection effect is obvious.Consolidate stopband compared to individual drift sand, drift sand consolidates stopband and shrub wind prevention and sand resistance junction belt
Wind-break potency significantly improve.As shown in figure 3, as the increase wind-break potency value variation of height becomes in reduction in each buffer zone
Gesture, from the peripheral area Luo Sha into oasis transient process, wind-break potency value at identical survey wind height, shrub wind prevention and sand resistance band > farmland
Shelter-forest > drift sand consolidates stopband, and drift sand consolidates the radix saposhnikoviae effect that stopband near surface 0cm-50cm protection effect is obvious, and shrub junction belt plays
Fruit is best.Sand-protecting barrier drift sand, which consolidates stopband and plays certain oasis periphery, checks winds and fixes drifting sand effect, and near surface 0cm-50cm wind speed weakens bright
It is aobvious, consolidated the Intercepting effects of stopband and shrub wind prevention and sand resistance band by drift sand, protection effect is most obvious, below 1.5 meters of survey wind height
Wind-break potency value 40% or more.Wind profile is the regularity of distribution of the wind speed along elevation.Agricultural protection forest is by arable land toothing
And the influence in forest belt, wind speed reduces by 47% with respect to the area Luo Sha at earth's surface 10cm, and difference surveys wind speed at wind height and is below the area Luo Sha
10%.
The second, wind-break potency improves.From the peripheral area Luo Sha into oasis transient process, wind-break potency at identical survey wind height
Value, shrub wind prevention and sand resistance band > agricultural protection forest > drift sand consolidate stopband, and sand-protecting barrier drift sand, which consolidates stopband and checks winds and fixes drifting sand to oasis periphery, to be had
Protection effect, near surface 0cm-50cm protection effect are obvious；Shrub wind prevention and sand resistance band is by the semifixed white thorn sand hill of fixation-and prevents
The influence of sand sagebrush (Artemisia filifolia) shrubbery in protecting band, protection effect is best, and 180cm is above 15% with wind-break potency value at inner height, and farmland is anti-
Protect a forest interior land surface toothing, shelter-forest height and forest belt configuration structure can have an impact earth's surface wind speed, high in all survey wind
Wind-break potency value is 10% or more at degree.
Third, sedimentary loading reduce.As shown in figs. 4-7, the foundation of protection system has remarkable result, oasis to dust storm is intercepted
The variation of protection system difference buffer zone total discharge of sediment are as follows: the area Luo Sha > drift sand consolidates stopband > shrub wind prevention and sand resistance band > farmland protection
Forest belt, the area Luo Sha total discharge of sediment 1078.03g are higher than drift sand and consolidate stopband 254.4%, and shrub wind prevention and sand resistance band is total with respect to sand-protecting barrier Qu
Sedimentary loading reduces 42.2%, the good shrub-coppice dune of vegetative coverage or the not high semi-mobile dune of vegetation coverage by sand dune and
The obstruction layer by layer of sparse vegetation, external stream or the stream being formed in situ can weaken, to substantially reduce into oasis
The dust storm intensity of flow in portion.
4th, secondary pollution is not generated.It is laid and is built with biodegradable acid fiber by polylactic (PLA) fabric and wheat straw interaction
Vertical drift sand consolidates stopband, and material environmental protection does not generate secondary pollution.
Although the embodiments of the present invention have been shown and described above, it is to be understood that above-described embodiment is
Illustratively, it should not be understood as limiting the present invention, those skilled in the art are in the scope of the utility model
Inside it can make changes, modifications, alterations, and variations to the above described embodiments.
