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.
