Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of alpine open-pit closed-pit mining area ecological restoration vegetation configuration method and application based on the ecological niche, to solve the problems in the prior art mentioned above, through the screening configuration of herbaceous plants, the planting of shrubs and trees can be significantly improved. The vegetation coverage rate in the mining area has been improved, the difficult problem of plant survival in the alpine mining area has been solved, and a new research idea has been provided for the ecological management of the mining area.

Embodiment 1

[0031] A ecological niche-based vegetation configuration method for ecological restoration in alpine open-pit closed-pit mining area

[0032] Taking the Zhalainuoer closed-pit open-pit coal mine as an example, the vegetation configuration in the restoration area is carried out according to the ecological niche of the plants in the surrounding restoration area, specifically:

[0033] Screening of herbaceous plant varieties sown in the first year: Statistics and calculation of the importance value, niche width and niche overlap value of herbaceous plants in the undisturbed area around the undisturbed area of ​​the Zhalainuoer closed-pit open-pit coal mine, the results are shown in Table 1 ~ Table 3;

[0034] The specific method is: use the ecological niche survey method to set up sample plots in each restoration area, and use the form of extensive survey or direct counting method to obtain the species type, number of species, number of plants, Basic data such as herb coverage, ...

Embodiment 2

[0073] Same as Example 1, the difference is that in step (1), the seed quantity ratios of quinoa quinoa, pigweed, barnyardgrass, Stipa baikal, and Artemisia argyi are 2:1.2:1:0.8:1.5.

Embodiment 3

[0075] With embodiment 1, difference is, the seed of tall fescue, wild mugwort, chrysanthemum chrysanthemum, gray green quinoa, barnyardgrass, pig hairy vegetables, reed, multi-stem vetch, amaranth, Mengshan lettuce in step (2) Quantity ratio 1.5:2:1:1.5:1:1.5:0.8:2:1:0.5.

Abstract

The invention relates to an ecological restoration vegetation configuration method for an open-air closed-pit coal mine in the alpine region and the application of the ecological restoration vegetation configuration method. Pioneer herbaceous plants are sown in the first year, the herbaceous plants are selected according to herbaceous species distributed in a non-interference area adjacent to the edge of a coal mine after stopping mining activity for one year, the importance value of the herbaceous species is greater than 0.05, the ecological niche width is greater than 1, and the ecological niche overlapping value of the herbaceous species and other species is not 0; the site conditions of the plants are preliminarily improved; shrubs and herbaceous plants are planted in the second year, and species with the important value larger than 0.03, the ecological niche width larger than 1 and the ecological niche overlapping value not equal to 0 with other species in the same area in the first year are selected as first supplementary herbaceous plants for replanting; from the third year to the fifth year, arbor is planted. Meanwhile, species with the important value larger than 0.03, the ecological niche width larger than 1 and the ecological niche overlapping value with other species not equal to 0 are selected in the non-interference area to serve as a second complementary herb for replanting, and succession of the ecological system is accelerated.

Description

technical field [0001] The invention relates to the technical field of ecological restoration of open-pit mines, in particular to an ecological niche-based vegetation configuration method and application for ecological restoration of alpine open-pit closed-pit mining areas. Background technique [0002] The mining process destroys the ecological environment and causes environmental pollution. The vegetation in the mining area is destroyed, the topsoil is stripped, the water and soil loss is serious, and open-pit mining, ground subsidence and the accumulation of waste from mineral processing have produced a large number of mining wasteland, which has caused local damage. Serious soil erosion and environmental pollution have affected the development of local economic construction. In order to improve the ecological environment of the mining area and effectively utilize the mining wasteland, it is necessary to carry out ecological restoration of the mining wasteland, and vegeta...
