Abstract

A system for preventing and treating desertification features that the artificial trees are arranged in desert and sand source of sand-dust squall, at both sides of railway or highway passing through desert, or in the isolating band between desert and oasis.

Description

System prevents and controls desertification

Patent of the present invention belongs to environmental science.

Because people are to the felling of forest, the variation of weather, the population of sharp increase and overfarming and herd cause my the northern area deterioration of the ecological environment, and the desertification of land degree is serious.From the sixties every year on average with 1560 square kilometres speed, develop into the nineties of 2460 square kilometres desertification speed expanded every year on average.Country is annual to cause direct economic loss up to 54,000,000,000 yuans because of desertification endangers.

The method that prevents and controls desertification at present is exactly the existing wildwood of protection energetically, builds artificial forest, transforms grass seeds protection grassland, concedes the land to forestry, and builds farming, woods, herds the ecological engineering of three combinations, though obtain significant results.But the speed of desertification expansion is faster than building anti-expansion woods, and its situation is very severe.Therefore, we should adopt more initiatively and more efficient methods, go to prevent and treat desertification expansion and sandstorm harm, the effect that " system prevents and controls desertification " that I invent just has this function.Its method is the areas such as sand plain ground in desert area and sandstorm, and a kind of engineering system with shelter-forest function and shape is installed.It has the wind speed of reduction, catch blowing sand, keeps the sun off to reduce the function (not comprising light and effect) of ground surface moisture content evaporation, regulates the ecological environment of this area.Make this area's ecological environment adapt to the plant growth gradually, create conditions for reproducing natural forests.

The purpose of the system that prevents and controls desertification: be the prevent and control desertification exhibition of protecting and sandstorm harm.We produce good ecological environment with " system prevents and controls desertification ", use again: the ecological environment of " well " changes the Desert Area ecological environment, vicious circle is become benign cycle, for plant is created favourable life condition.

The system of preventing and controling desertification is function and the shape with shelter-forest, subjects such as utilization bionics, mechanics, civil engineering, the engineering system of selecting for use material manufacturings such as chemical industry, civil engineering to form.It arranges " false tree " in length and breadth by several, and with the engineering system that cross base four ends of " connecting rod " connection " false tree " are formed, we claim the system of preventing and controling desertification.It mainly is made up of three parts, that is: false tree, connecting rod, shaft coupling etc.False tree: the shape and the made tree of function that are the imitation tree.It is by a cross base, trunk of base support, the Zhi Gan that evenly distributes of 2/3rds places on the trunk, Zhi Gan last even branch branch and leaf.Connecting rod: be the bar that connects cross base four ends of false tree, an end of bar is a circular port, and the other end is a slot, and it plays a part stable this " system ".Shaft coupling: be cross base four ends of false tree and the tie point of connecting rod end points.Be the angle and distance of regulating false cross base of tree and connecting rod, guarantee that the distance between the false perpendicular to the ground and false tree of trunk of setting equates.As figure 4

The benefit of the system that prevents and controls desertification is that it can be installed in very short time and form, and plays the effect of wind prevention and sand resistance, needs the time in 8 years at least and plant shelter-forest.It can all play a part wind prevention and sand resistance at all seasons, and the trees of shelter-forest are not because winter-spring season has leaf, so the effect of anti-dust storm is very little.It can regulate ecological environment at desert area, the husky source area of sandstorm.Because the effect that branches and leaves shelter from sunshine can reduce the evaporation of ground surface moisture content, for plant life creates conditions.It can prevent and control desertification and expand and sandstorm harm, reduces economic loss can for country.

Patent of the present invention is described further figure 1 below in conjunction with figure: be the partial structurtes intention of " preventing and treating the desertification system ", figure 2: be the schematic diagram of " false tree ", figure 3: the schematic diagram that is " connecting rod ".Figure 4: the schematic diagram that is " shaft coupling ".

The mode of the realization of patent of the present invention " system prevents and controls desertification ": exactly critical piece is created, critical piece has cross base, trunk, Zhi Gan, tree and leaf, connecting rod, shaft coupling.Make cross base, trunk, connecting rod mould, build and form.The material of selecting for use is that concrete of steel wire adds wood chip, makes limb, branch and leaf is built with mould and compacting forms, and the material of selecting for use is steel wire, plastics, nylon taffeta.The manufacturing of shaft coupling also is that die casting forms, and the material of selecting for use is a cast steel.We assemble the parts that these apparatus manufacture, and have just realized our needed new product.I.e. " system prevents and controls desertification ".

Claims

Patent name of the present invention: system prevents and controls desertification

Theme is prevent desertification expansion and sandstorm harm, administers the ecological environment of Desert Area, with method, viewpoint change this area ecological environment of environmental science.Its feature: it has function and the shape of shelter-forest, subjects such as utilization bionics, mechanics, civil engineering, the engineering system of selecting for use material manufacturings such as chemical industry, civil engineering to form.The system that prevents and controls desertification arranges " false tree " in length and breadth by several and forms, and with cross base four ends of " connecting rod " connection " false tree ", is being fixed " connecting rod " and cross base four ends, the engineering system of being formed by " shaft coupling ".Promptly " system prevents and controls desertification." (Fig. 1)

1, false tree: be function (except light and the effect) and the shape of imitation tree, by a cross base, trunk of surface bearing on the base, trunk face 2/3rds parts Zhi Gan that evenly distributes, branch and leaf evenly distribute above the Zhi Gan.Leaf Poplar leaves, the willow leaf etc. of imitating.(Fig. 2)
2, connecting rod: it is the bar that connects " false tree " cross base four ends, and an end of bar is circular hole, and the other end is the hole of elongated, works to regulate adjacent two " false tree " distances.(Fig. 3)
3, shaft coupling: be circular sheet, there is a circular hole at the center, and one side wherein has straight-tooth, and another side is the rectangle of projection, and rectangular center is a center with the thick length of circle.Can regulate the angle of adjacent two " false trees " and play fixation.(Fig. 4)
