Abstract
The invention relates to a vegetation protection and recovery technology for a plateau high-cold steppe area, which comprises a turf and grass seed selecting technology and a planting technology. The invention is characterized in that the planting technology adopts superior grass for vegetation recovery in an off-line project, adopts grass that livestock dislike to graze for roadbed protection and vegetation recovery, and adopts two construction technologies of turf transplantation and grass seed planting as frozen soil protecting measures. In the invention, species and planting technologies can be selected for different road area environments, the survival rate of plants at the early stage is improved, the capacities of living through the summer and winter are enhanced, the species diversity is increased, the recovery progress of vegetation at the early stage is accelerated, the operation is simple, and the working efficiency is high. The invention has the beneficial effects that a temporary steel protecting cylinder pulling technology with a steel pipe column ensures accurate positioning of a middle column, and the cost is reduced by turnover and reuse of the steel protecting cylinder.
Description
Technical field
The invention belongs to field of civil engineering, particularly relate in highland and severe cold grassland area road and rail engineering project vegetative protection and recovery construction technology.
Background technology
At present countries such as Russia, the U.S., Canada, Norway, Denmark are only at high and cold area, take to transplant, plant, cultivate, broadcast and plant and spray such as plants at technology at environmental engineering aspects such as newly-built atural object vegetative protection and recoveries.Surviving the winter in area, China highland and severe cold grassland, vegetation cover degree promotes slowly after the summer, and recovery effects is poor.Two small highways and bavin wood railway engineering are located in area, highland and severe cold grassland; still do not have both at home and abroad under the condition of area, highland and severe cold grassland; the form a complete and comprehensive system for collecting real estate fees precedent of construction technology of highway, railway engineering vegetative protection and recovery, still aspects such as the selection of unmatchful species, build and plant technology, soil protection and Monitoring and Controlling are systematically discussed.
Summary of the invention
The problem that the present invention need solve is: a kind of highland and severe cold local highway and railway engineering revegetation and construction of prevention work technology are provided, can guarantee road structure safety, reduce Rail Highway maintenance cost, ensure the herbage quality, improve grass yield.
Technical solution of the present invention is: highland and severe cold grassland area vegetative protection and recovering technology; comprise and select turf, grass-seed and build and plant technology; it is characterized in that: described build and plant technology adopts: good forage is as the grass seeds of the revegetation of the outer engineering of line; livestock is not liked the grass seeds of edible herbage as subgrade protection and revegetation; turf is transplanted and two kinds of construction technologies of grass-seed plantation, the measure of protection frozen soil.There is different suitable build and plant technologies the different regions of highland and severe cold grassland region, by test and analyze, can effectively improve the technology of revegetation cover degree after the summer of selecting to survive the winter.By soil protection technology such as effective vegetation soil safeguard structure design, soil soverlay technique, soil maintenance technologies; can not only improve vegetation cover degree, species diversity; ensure basin water safety; safeguard Characteristics and Water Conservation Function; and can effectively protect frozen soil environment; protection agent structure operation security reaches the minimum influence degree that vegetation is survived simultaneously, improves the revegetation process greatly.
Embodiment
1, technology is selected in option of species technology and planting
At semiarid, moistening and half moistening highland and severe cold grassland region, topsoil has been subjected to serious interference, though have in the surrounding environment many other plants seed can by carry such as anemophily, entomophila, animal, rainwater carries and mankind's activity arrives the territory, road, but generally can not germinate smoothly and grow, the natural vegetation restoration process is slow.Must be from selecting suitable plant society, improving plant growth environment (being mainly soil environment) two aspect developing build and plant technologies.The plant society technology that the present invention adopts draft, woody plant to combine is transplanted and two kinds of vegetation plantings recoveries of grass-seed plantation construction technology by turf, and two kinds of technology are used in highland and severe cold grassland region vegetative protection and ecological recovery construction, and effect is obvious.
2, protection frozen soil technology
At highland and severe cold area vegetative protection and recover at first will protect frozen soil in the construction, the vegetation after the planting to make as far as possible with face of land frozen soil upper limit in season with destroy before substantially at same elevation, for plant growing provide and destroy before identical freeze thawing environment.
3, protection soil technology
Main feature is in the vegetation construction of highland and severe cold area: be necessary for the matter and energy that vegetation provides rational underground ecological position, surface vegetation and the dead leaf layer that falls supplies nutrients for subterranean microorganisms, and natural heating power barrier is provided for the frozen soil that underlies, influence face of land solar radiation, ground temperature and amplitude thereof are had filtration and attenuation, can also reduce the seasonally thaw layer water evaporates.
The present invention is applicable to the typical grassland and the sylvosteppe of the loess growth landforms band that height above sea level 2800m is following, as grassland plantation, cultivation and the drilling technology in Qinghai-Tibet the Huangshui River water river valley, basin, Guide; Be applicable to the typical grassland that height above sea level 2800m～5200m is above, as encircle grassland, southern foot, the Qilian mountains, grassland, the foot of a hill or mountain, Sun-Moon Mountain north and south and the sources of three rivers head grassland in Qinghai Lake basin, no matter being wetland landforms, high mountain landforms or grassy marshland landforms, generally is that main additional transplanting, additional planting technology are auxilliary with the implantation technique.
