Problems solved by technology

[0037] The main purpose of the present invention is to overcome the lack of turf protection and utilization planning in the existing engineering practice, the allocation and utilization of turf areas is relatively random, the lack of scientific and reasonable planning for turf planting utilization and sowing and building lawns, and insufficient consideration of the benefits of water and soil conservation The technical problem to be solved is to make the process control more scientific and reasonable, with the best ecological benefits, which is very suitable for practical use.
[0038] Another object of the present invention is to overcome the improper design of turf storage methods in existing engineering practice, the inability of turf storage technology to adapt to the schedule and requirements of road construction, the difficulty of maintenance and management during turf storage, and the prominent death phenomenon of turf piles, etc. Disadvantages, the technical problem to be solved is to make the storage of turf comprehensively consider the impact of the storage process on the survival rate and survival time, and to take into account the construction process and time requirements of road engineering

Embodiment 1

[0191] A highway is located in the alpine region of the Qinghai-Tibet Plateau, and the vegetation types along the way are mainly alpine grassland, alpine meadow, desert grassland, etc. During the construction of the highway, in order to realize the scientific planning, efficient protection and utilization of vegetation along the whole line, the inventor proposed method, as follows:

[0192] (1) Designate the protection level of turf

[0193] 1) Collect remote sensing data for basic analysis

[0194] Collect the vegetation types along the highway project and the vegetation coverage data measured by NDVI, and perform grid processing, use GIS analysis tools to extract highway vector data, and use the vector analysis tool "buffer" in GIS to extract 5km buffers on both sides of the highway area, as an assessment area for turf protection on both sides of the road;

[0195] 2) Delineate the level of turf protection

[0196] Determine the turf protection level according to the extr...

Embodiment 2

[0270] For the turf protection of this road, according to the rainfall conditions, wind and sand conditions, management methods for road surface runoff and turf propagation requirements, different forms of turf planting and sowing are used to build lawns. The specific layout is as follows:

[0271] For slopes dominated by wind erosion and weaker in water erosion, checkerboard arrangement is adopted, see Figure 12 , among the figure 9 is the road surface, 10 is the road shoulder, 11 is the groove line, 12 is the planting soil, and 13 is the turf block. The slope ratio of these slopes is 1:2, and the slope height is less than 3m. Backfill the soil between the turf blocks 13 and sow grass seeds, that is, use the turf blocks 13 to carry out checkerboard planting on the slope, that is, the upper shoulder position of the road side and the lower slope foot. Position, left side, right side each pave and plant a piece of grass band, and in the enclosed grid frame of enclosing synthesi...

Embodiment 3

[0276] Similarly, for this road, this embodiment adopts another method when evaluating vegetation recovery. This method not only extracts the data of three environmental factors: annual precipitation, annual average temperature, and soil type, but also extracts the data of growth factors. Seasonal and monthly average temperature, growing season precipitation, growing season soil moisture value, altitude, slope environmental factor data, and vegetation type and vegetation coverage factor data are used as evaluation indicators for vegetation restorability to construct vegetation restorability evaluation model, the specific method is as follows:

[0277] Collect vegetation, soil spatial distribution data, remote sensing data, digital elevation model and meteorological data along the highway, and generate raster data of the same size unit after digital processing and spatial correction. Apply spatial pattern analysis, multi-factor superposition analysis, qualitative and quantitativ...

Abstract

A turf protection utilization method is provided for turf protection utilization programming and planning, and comprises the following steps: delimiting a turf protection level according to nature vegetation types and coverage; delimiting a vegetation retrieval level according to rainfall, temperature and soil factors; carrying out field investigation to check two said levels; superposing and delimiting a plurality of ecology control sections; determining the turf excavating technology according to the vegetation types and coverage in each ecology control section; selecting three protection technologies according to road engineering construction progress and turf utilization time intervals, wherein the three technologies include piled stacking, layered stacking, and skeleton layered temporary planting; determining three planting modes according to wind erosion and water erosion characteristics and propagation coefficients, wherein the three planting modes include a chessboard type, a tic-tac-toe mode and a bar stripped mode. The method can scientifically unify turf protection and utilization planning, storage and utilization, thus providing best ecology benefits; the turf protection utilization method is practical in applications.

Description

technical field [0001] The invention relates to a method for protecting topsoil vegetation in the field of ecological environment, in particular to a method for protecting and utilizing turf. Background technique [0002] In the Qinghai-Tibet Plateau and the alpine permafrost region in Northeast my country, due to the high altitude and severe cold climate, the plant growth is extremely slow, and due to the harsh growth environment conditions, the plant species are extremely single and the ecological environment is extremely fragile. In the construction of infrastructure such as roads and railways, it is inevitable to cause damage to the vegetation along the line, and once it is damaged, it is very difficult to restore. Not only are there few types of plants that can be restored, but the restoration effect is not ideal. In the alpine and high-altitude areas such as the Qinghai-Tibet Plateau, a large number of experiments on seed building have been carried out, but the results...
