Embodiment 1

[0043] The repaired mine of this embodiment is the mine slope of a certain iron mine in the eastern part of Liaoning Province. On the basis of slope shaping, according to the technical process of the present invention ( figure 1 ), carry out mine ecological restoration, the restoration area is 3 hectares, and the restoration time is 3 years.

[0044] Step 1. According to the investigation of regional biogeographic climate and local mine natural environment, the local mine plant community spectrum (Table 1) and the mine soil formation process spectrum (Table 2) are obtained. The local soil type is mainly loam.

[0045] The local mine plant community spectrum (Table 1) is based on the constraints of the local biogeographical climate and the local mine natural environment, through the quadrat survey of the top plant communities that grow stably in the local mines, and the advantages of the main plant species are obtained. Spend.

[0046]The spectrogram of the soil-forming proces...

Abstract

The invention is applicable to the technical field of ecological restoration, in particular to a mine ecological restoration method based on induced succession of plant communities. Based on the response relationship between plant community succession and soil formation process (soil nutrition) in the mine to be restored, the suitable plant species were screened and combined in the soil microenvironment of the mine to be restored to induce the rapid succession of plant community, which accelerated the soil formation process of the mine to be restored and realized the rapid and accurate ecological restoration of the mine. The method of the invention can realize the quick and accurate ecological restoration of the mine and the self-restoration of the sustainability of the mine.

Description

technical field [0001] The invention is applicable to the technical field of ecological restoration, and specifically relates to a mine ecological restoration method based on plant community induced succession. Background technique [0002] my country's mine land reclamation work started earlier, around the 1950s, but it was not until the early 1990s that my country's research on ecological restoration began, and at the same time some feasible ecological restoration technologies were developed. [0003] Existing mine ecological restoration technologies are mainly divided into three categories. The first category is to improve the physical and chemical properties of the soil in response to the problem of poor soil at the start-up stage of mine ecological restoration. By adding water-retaining agents and nutrients to the soil (ZL201410074186.5, 201610670324.5, 201610363256.8, 201710020819.8), it can promote plant growth. Growth, accelerate the vegetation restoration of mines ...
