FIG. 1 is a flow chart of a method for water and soil conservation and re-greening in alpine regions according to the present invention.
Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present application based on the embodiments herein.
Embodiments of the present invention are described in further detail below with reference to the accompanying drawings.
As shown in fig. 1, the application provides a water and soil conservation and greening method in alpine regions, which comprises the following steps:
s1: and collecting and treating the turf and the surface soil before site construction, re-paving the treated surface soil in the site after the site construction is finished, and re-paving the turf on the surface soil after maintenance treatment.
In some alternative embodiments, step S1 comprises:
s11: and stripping the original turf of the field.
Before the site is subjected to engineering construction, the original turf on the site is peeled, and the root system of the turf is ensured to be complete as much as possible during peeling.
S12: the peeled sod is stored in a storage area for storing the sod, and the sod is pressed and maintained by sprinkling water periodically after being covered by a dense mesh net.
It can be understood that the storage of the turf should consider the environmental influence of high and cold in the plateau, and to improve the survival rate of the turf, the turf should be regularly maintained by sprinkling water, and the death of the turf caused by overlong stacking time, improper storage ecological area, improper subgradicular soil, improper root soil protection and the like is avoided.
S13: and cleaning the surface of the field in different areas, stripping and collecting the surface soil, and storing the surface soil and the turf separately.
The surface soil is a storage carrier of a plant seed warehouse, and has high nutrient content, especially for severe cold areas and fragile plant population, so that in the construction surface cleaning process, areas are divided, and surface cleaning construction is performed step by step, so that the problem of larger damage range caused by surface cleaning at one time is solved. And after the surface cleaning is finished, stripping and collecting surface soil in the field, and screening impurities in the surface soil to improve the survival rate of the follow-up grass re-planted on the surface soil and the planting of the seedlings. Soft soil layers, silt, humus soil, cobble, boulder, garbage, tree roots, wet soil of paddy fields, frozen soil and the like which are not suitable for growing turf and seedlings are removed by screening.
In some alternative embodiments, after the site construction is finished, the surface soil collected by the original site is paved in the site again, and the turf on the original site is paved on the surface soil again, when the quantity of the turf is insufficient and the paving effect is poor, a method of combining paving and sowing can be adopted, so that the turf covering effect of the site can be improved.
Especially for the side slope zone, the mode of lattice planting and fiber blanket can be adopted when the turf is planted. The slope anchoring mode of the concrete frame lattice beam is adopted, the soil engineering lattice chamber is embedded in the concrete frame lattice beam, the surface soil is paved in the soil engineering lattice chamber, then the turf, seeds and nutrient substances are mixed to form a plant fiber blanket, and the plant fiber blanket is paved in the soil engineering lattice chamber, so that the water and soil loss can be reduced, and the survival rate of the turf and the planting quality of the turf can be improved.
In some alternative embodiments, when the slope of the field is less than 60 °, a plant bag is laid on the surface soil.
Specifically, the planting soil after manual screening is bagged to form a planting bag, and the planting bag is piled on the surface soil, so that the bottom of the planting bag is tightly contacted with the basal plane of the surface soil, the exposed area of the surface of the planting bag is reduced, and the root rooting depth of grass roots in a side slope zone is increased.
It can be understood that the planting soil has good physical and chemical properties, loose structure, ventilation, strong water and fertilizer retention capability and is suitable for the soil for plant growth. If the planting soil is not used, the raw soil and the organic fertilizer or the compound fertilizer can be used for replacing, and fine sand can be added when the viscosity is too high. The plant-growing bags are mutually overlapped and stacked on the surface soil, and the paving thickness of the surface soil is between 4cm and 6cm at the moment, so that the depth of a root system when the plant-growing bags are pricked into the surface soil is increased, and the water and soil conservation capacity of a site slope is improved. Meanwhile, the function of soil conservation and water seepage of the plant growth bags reduces the hydrostatic pressure of the side slope, ensures the normal communication of water in the soil, provides a medium for vegetation to survive, and ensures that the side slope greening effect of the field is more obvious and more effective.
In some alternative embodiments, the surface soil needs to be treated, including specifically, soil protection and fattening, to enhance the corrosion resistance of the surface soil.
By way of example, the polymer compound fertilizer can be sprayed on the surface soil, and a consolidation protection layer is formed on the surface layer and pores of the surface soil to wrap the surface soil through the self-polymerization of the polymer material, so that the strength of the surface soil is enhanced, and the corrosion resistance of the surface soil is improved. The high molecular compound fertilizer is environment-friendly, nontoxic and biodegradable, uses water as a solvent, has no secondary pollution, is simple to construct, has rapid reaction, does not need additional maintenance, soil fixation and fertilizer enhancement, and has obvious growth promoting effect.
In some alternative embodiments, the treated surface soil can also be mechanically, pneumatically or hydraulically added with continuous fiber filaments or short fiber filaments to a certain extent to form reinforced soil. Due to the effect of the fiber, the reinforced soil body forms a three-dimensional structure, the integrity of the reinforced soil body is enhanced, the strength is increased, the shock resistance is also enhanced, and therefore the water and soil conservation effect can be further optimized.
S2: and connecting the grass layer, the surface soil layer and the basal layer of the field into a whole by adopting ecological concrete so as to form a water and soil conservation layer.
It can be understood that the ecological concrete has higher compressive strength, can meet a certain slope load, has a certain porosity, has good drainage and water permeability, and enables grass planting root systems to penetrate through the ecological concrete and penetrate into the bottom soil so as to improve the integrity and ecology of the slope. The grass layer, the surface soil layer and the basal layer are connected into a whole by using ecological concrete, so that the field has strong anti-scouring performance.
S3: selecting seedlings of a plurality of specific plant varieties, and planting the seedlings on the water and soil conservation layer.
Because of relatively poor species diversity in high-cold and high-altitude areas, artificial cultivation and planting resources are limited, and pasture and economic plant planting are common. The vegetation coverage is improved according to the upper-propagation type herbaceous plants, the root systems of the lower-propagation type herbaceous plants are relatively developed, the slope protection effect is good, the leguminous plants can improve soil matrixes, the root systems of shrubs are developed, and the plants are main slope protection plants in the later period of ecological restoration. Therefore, the plant varieties are selected for configuration planting, and the native species are optimized to adapt to the natural environment of the place, so that the invasion risk of the species is reduced. Such as Tongde short-burst grass, hai Poa pratensis, qinghai Cold-land Poa pratensis, qinghai Chinese fescue, etc. Meanwhile, in order to avoid the damage of the species diversity principle caused by the use of a single species, plant varieties with different growth heights are considered in a vertical structure to be configured, so that the ecological restoration early-stage landscape greening effect can be considered, and meanwhile, the vegetation slope protection function in the later growth stage is ensured. Promote the formation of a forest stand community which takes arbor as a main body, combines arbor and shrub, has reasonable and stable structure and high-efficiency and coordinated functions.
In some alternative embodiments, a plurality of seedlings of specific plant varieties are selected, and after the seedlings are planted in the field, moisture and heat preservation measures are required for the seedlings. The method comprises the following specific steps:
s31: and (5) selecting stone blocks with the diameter of 5-15 cm on site after seedling planting, and covering the stone blocks on the whole hole surface of the pot bottom shape by taking the seedlings as the center.
The stone is covered on the hole surface with the nursery stock as the center, so that rainwater can be carried, and the evaporation of water in soil can be effectively inhibited.
S32: covering the hole surface with colorless transparent film, and punching holes in the film to facilitate rainwater penetration into the hole.
The plastic film is covered by a colorless transparent film, which is covered on a hole surface which takes sapling as the center and is arranged into a pot bottom shape, the periphery is compacted by soil to prevent wind and blow away, and then 5 to 8 holes are drilled on the film in a punctiform manner, so that rainwater can conveniently permeate into the holes, and the plastic film can be covered to improve the ground temperature and maintain the soil moisture content.
S33: covering the periphery of the above-mentioned seedling with weed, wheat straw and leaf, etc.
The grass covering means that weeds, wheat stalks, leaves and the like are covered around the nursery stock, the covering thickness is generally 2-3 cm, and then a layer of soil with the thickness of 2 cm is pressed on the nursery stock to prevent the soil from being blown away by wind, so that the grass covering can increase the organic matters of the soil and improve the soil fertility.
In some alternative embodiments, after step S3, further comprising:
s4: and carrying out in-situ identification on the field, establishing a three-dimensional model, and monitoring the displacement condition of the water and soil conservation layer in real time.
It can be understood that the displacement condition of the soil and water conservation layer is monitored, so that the soil and water conservation condition of the field can be monitored, and measures can be taken in time. For example, a slope anchoring mode of a concrete frame grid beam is added, or the laying area of a plant growth bag is increased, or the thickness of ecological concrete is increased, or vertical piles are arranged in a site, so that the displacement of a water and soil conservation layer is controlled.
In some optional embodiments, monitoring the displacement of the soil and water conservation layer in real time includes arranging surface deformation measuring points in a set area of the field, and observing the displacement of the surface measuring points of the soil and water conservation layer by a corner intersection method.
The corner intersection method is a method of respectively erecting instruments on two or more known points to observe the horizontal angle and the distance of the point to be fixed, and calculating the coordinate of the point to be fixed according to the coordinate of the known points, the observed angle value and the distance.

The form of the flood control drainage works can be determined according to the specific situation of the site, the upstream catchment area and the surrounding terrain geological conditions, including but not limited to the combination of open row and arrangement.
Optionally, the intelligent network management platform for site ecological restoration is integrated with four places through in-situ identification, a muck allocation information platform, unmanned aerial vehicle dynamic supervision and video real-time transmission.

Specifically, in some optional embodiments, monitoring, in real time, the deep deformation condition of the site, the osmotic water pressure condition of the site, and the seepage flow condition of the site includes:
and drilling and burying the inclinometer pipe vertically at the key section of the field so as to monitor the deep deformation condition of the field and the flood control drainage engineering.
And arranging a water-permeable flower pipe at the bottom of the field so as to monitor the change condition of the water pressure of the inside of the field.
