Stripped live plant fence type sand-barrier protection system planting method

Abstract

The invention discloses a stripped live plant fence type sand-barrier protection system planting method, comprising the following steps: determining specific tasks and objectives of living sand-barrier protection; selecting living sand-barrier tree species; planting and designing before planting; firmly building and planting stripped sand; planting seedlings; using a living sand-barrier nursing method; and monitoring, supplementing, and improving functions. The method develops double sand-barrier protection advantages of high standing fences and plant sand-control through applying the technical scheme of living sand-barrier system combined design of specific blowing wind environment prevention regions and planting in real site. The method gives consideration on natural ecological restoration attribute of vegetation evolvement, and provides a novel ecological protective technology mode in which biological and mechanical measures are coordinated with each other. The method can satisfy the following protection functions: maintaining fragile water balance of inter-barrier natural sand, service life is more than 30 years, the sand-barrier protection system promotes quicksand to deposit in the prevention regions and overall sand surface is lifted, quicksand entry of a protected region is lower than 10% of sediment runoff of natural locality.

Description

technical field [0001] The invention relates to the technical field of windbreak and sand fixation, in particular to a method for building strip-shaped living plant fence-type sand barrier protection systems. Background technique [0002] The main characteristics of the sandstorm hazard area are: empty and dry sandy surface, windy and strong winds occur several times during the year, the sand material migrates with the wind, burying farmland, roads, and infrastructure, and encroaching on the normal human activity space. It is a sandstorm. It is also an important source of smog weather and a key area for the prevention and control of ecological and environmental disasters. [0003] The inland areas of northern China are dry and waterless, and the vast sandy wastelands are sparse in natural vegetation and seriously decayed, with poor surface stability. Wind and sand invade oases and towns, and sand and dust are polluted by the wind. These are the main environmental problems in...

AI Technical Summary

Problems solved by technology

[0043] Aiming at the prior art 6) a sand-fixing method that uses a covering plate to guide the formation of plant sand barriers: the cost per unit area of ​​treatment is high, the plants are dense, the water consumption is high, and the control range is limited. Generally, the natural water content of arid sandy land cannot bear the load, and the control effect is limited;

[0044] Aiming at the prior art 7) a compound sand control method: it is only limited to the sandy land with good water conditions and light sandstorm damage, and the sand-blocking effect of herbal plants is poor, and the protection duration is short; it is difficult to popularize and apply in arid sandstorm areas;

[0045] Aiming at prior art 8) Suspended concrete block slab sand-retaining fence: only forcibly intercepting quicksand, and causing a large amount of quicksand to accumulate in front of the fence, which is not conducive to dredging, easy to form new sources of sand damage, and the cost of treatment is high, and the use time is limited. It is difficult to be used for large-scale sandstorm environmental ecological environment governance;

[0046] For the existing technology 9) four similar patent applications: only forcibly intercepting quicksand, and making quicksand accumulate in large quantities in front of and behind the fence, which is easy to form new sources of sand damage; and the cost of treatment is high, the scope of control is limited, and it is difficult to carry out large-scale Ecological Control of Sandy Environment
