Problems solved by technology

[0003] However, there are differences in mine dumps, tailings ponds, and stopes, but the ecological restoration lacks quantitative design, and the restoration is designed and constructed relying on engineering experience

Embodiment 1

[0046] The repaired mine of this embodiment is the dump site 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 ), to carry out the quantitative design of mine ecological restoration measures, with a total area of ​​60ha, and the restoration design and test verification time is 2 years.

[0047] Step 1: Obtain data and build a model;

[0048] 1) Collect sub-watershed division data

[0049] DEM data, covering the mining area to be repaired, the accuracy is 5m, see figure 2 ;

[0050] 2) Collect soil erosion assessment data

[0051] Hydrological data, surface runoff, monthly average data, statistical results are shown in Table 1;

[0052] Meteorological data, rainfall at the nearest weather station, daily average data, statistical results are shown in Table 1;

[0053] Land data, collect the land use map of the mining area to be repaired, the accuracy is 5m, ...

Embodiment 2

[0076] The difference between this embodiment and embodiment 1 is that the mine to be repaired is an iron ore mining field in the eastern part of Liaoning Province. The slope is larger than that of the dump site, and soil erosion is more likely to occur in the bare land, with a total area of ​​98ha.

[0077] Step 1: Obtain data and build a model;

[0078] 1) Collect sub-watershed division data

[0079] DEM data, covering the mining area to be repaired, the accuracy is 5m, see Figure 5 ;

[0080] 2) Collect soil erosion assessment data

[0081] Hydrological data, surface runoff, monthly average data, statistical results are shown in Table 5;

[0082] Meteorological data, the nearest weather station rainfall, is identical with embodiment 1;

[0083] Land data, collect the land use map of the mining area to be repaired, the accuracy is 5m, and the statistical results are shown in Table 6;

[0084] For the vegetation data, establish the vegetation types corresponding to the ...

Abstract

The invention is applicable to the technical field of ecological restoration, in particular to a mine ecological restoration method based on ecological zoning. The method comprises the steps of obtaining the basic data of the mine to be restored and establishing the SWAT model of soil and water loss evaluation; according to the SWAT model, performing ecological zoning and obtaining the soil and water loss of each ecological zone; adopting a scene analysis-test correction method to determine the repair measures. The invention starts from two major factors of soil and vegetation that affect mineecological restoration, and, through data collection, carries out ecological zoning and soil and water loss evaluation on the mine to be restored, so that soil improvement and ecological restorationmeasures of vegetation cover can be quantitatively determined simply and at low cost.

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 ecological divisions. Background technique [0002] my country's mine land reclamation work began in the 1950s, but the research work on ecological restoration in my country did not start until the early 1990s. Existing mine ecological restoration technologies are mainly based on soil improvement and plant species selection, which can be divided into two categories. The first category is the improvement of soil physical and chemical properties, such as adding water retaining agents, nutrients, etc. (ZL 201410074186.5, 201610670324.5, 201610363256.8, 201710020819.8) to the soil to promote plant growth. The second category, the selection of plant species for ecological restoration, usually selects barren-tolerant or pioneer plant species (ZL201110381203.6), and optimizes the layout of restoration plants ...
