Embodiment 1

[0027] An ecological restoration method for a steep slope in an abandoned mining area. The construction steps are as follows: Step 1, site preparation: firstly remove the slope base, slope surface weathering, and loose soft soil and rocks; to prevent potential safety hazards.

[0028] Step 2, making the planting base plate: the material is made of light steel material, slightly U-shaped, and the size is 50×30cm.

[0029] Step 3, laying out the planting base plate: anchor the planting base plate on the slope, with an interval of 1×1m, and inject into the slope at an angle of 70°.

[0030] Step 4, Proportioning the planting substrate: a. Collect the undisturbed soil around the treatment area, mainly to restore herbaceous plants, and the thickness of the covering soil is 5cm; b. Supplement the seeds of native plants around the treatment area, and select species from the native vegetation around the treatment area, which has strong stress resistance 1. Climbing plants are the bes...

Abstract

The invention relates to the technical field of ecological restoration, in particular to an ecological restoration method for steep slopes in abandoned mining zones. A large number of high cutting slopes are present in the abandoned mining zones, and hard rock formations, steep slopes and poor soil texture in the zones are difficult points for ecological restoration. According to the ecological restoration method, in order to realize three-dimensional greening of the steep slopes, and solve the ecological restoration problems of slope surfaces different in drop height and poor in stability, after a series of operations of soil preparation, planting base plate making, planting base plate laying, planting substrate proportioning, planting substrate laying, water supplement and final-period management, soil in each planting base plate is stable; plant seeds can drop down, and provenances are sufficient; moreover, supplemented species are all local native plants, and adapt to the ecological environment of the local zone, so that water and soil erosion is reduced, the survival rate is high, and the restoration effect in the aspects of vegetation coverage and species diversity is remarkable; geological disaster and hidden dangers including water and soil losses, damage and the like are completely eradicated, and after several years, the supplemented species are gradually fused with the natural ecology.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to an ecological restoration method for steep slopes in abandoned mining areas. Background technique [0002] Relevant studies have shown that the slag on the slope of the abandoned gold mining area is alkaline, with a pH value of 8.0 to 9.5, and the main body is a variety of mineralized and oxidized medium and fine-grained granite. The slag structure is loose, low in strength, contains a lot of sand and gravel, very little soil, poor soil, strong water holding capacity, and strong water permeability, so the stability of the slope is poor. In the natural state, mudslides and gullies are likely to form on the slag slope after rain, causing large-scale landslides, which are extremely destructive; in dry seasons, sandstorms and dust are easily formed, causing harm to people, livestock and the environment. [0003] In order to realize the ecological safety of slopes in a...
