Embodiment 1

[0028] A method for ecological restoration of northern arid mining areas provided by an embodiment of the present invention, specifically, includes the following process steps:

[0029] (1) Determination of the construction plan for flat plate and slope ecological restoration

[0030] Determine the ecological restoration plan according to the data collection and analysis results of the original covering soil thickness, soil quality, and the survival of the original planting plants in the mining area, slope slope, slope length, soil quality, covering soil thickness, and the survival of the original planting plants;

[0031] (4) Flat Disk Repair

[0032] The flat plate is divided into three grades, the first grade: good soil quality (high organic matter content, perfect particle size gradation, good aggregate structure), the thickness of the original covering soil is more than 300mm, and the survival rate of the original planting plants is 20%-40%; the second grade : Poor soil ...

Abstract

The invention discloses an ecological restoration method for a northern arid mining area. The ecological restoration method for the northern arid mining area is used for ecological restoration of mining areas with northern annual rainfall less than 300mm. Ecological big data is utilized to fully analyze soil texture conditions of a flat plate and a side slope of a mining area, and in combination with investigated related data about water, soil, gas and the like and conditions of vegetation, soil and the like, different remediation schemes are applied according to different soil layer structures, soil improvement is carried out, drought-resistant plants are selected for planting, and new work maintenance is carried out according to climate environment. According to the ecological restoration method for the northern arid mining area, in the later-stage maintenance, in order to enable the plants to survive better, local indigenous plants are introduced, growth of the flat plate and slope vegetation is induced and managed, the damaged ecological environment is wholly restored or close to the natural ecological style and appearance.

Description

technical field [0001] The invention relates to an ecological restoration method, in particular to an ecological restoration method for mining areas in northern arid regions. Background technique [0002] In recent years, with my country's economic development and increasing demand for mineral resources, the development and utilization of coal resources has caused a series of ecological and environmental problems. The loss of biodiversity in plant communities, the decline of groundwater levels, changes in the composition of soil and vegetation structures, soil erosion and frequent sandstorms have led to ecological deterioration and seriously affected the normal functioning of ecosystem services. Therefore, vegetation reconstruction and ecological restoration in mining areas are urgent problems to be solved. Especially the arid areas in the north are seriously affected, with drought and little rain, and vegetation restoration work is even more difficult. [0003] In view of...
