Abstract
An ecological restoration method of waste dump vegetation is provided, comprising the steps of leveling waste dump and sowing vegetation, wherein the specific steps are as follows: using tailings sands to fill gaps of crushed stones on the slope and plane of the waste dump; using mountain surface soil to cover the crushed stones till that the crushed stones are covered completely; irrigating the waste dump till that the mountain surface soil on surface of the waste dump is wet completely; sowing herbs on the slope of the waste dump; planting seabuckthorn in the middle of the slope; planting Robinia pseudoacacia seedlings on the lower part of the slope; planting cotton climbing plants at the root of the slope; planting Robinia pseudoacacia on the plane; and normally managing the vegetation on the other positions. The invention solves the problem that lots of the tailings are stacked, reduce usage amount of the soil and reduce engineering cost; different plants are planted on different positions of the slope of the waste dump; due to the optimal distribution method, the germination rate of the vegetation and survival rate of the seedlings are improved; the restoration effect of the waste dump vegetation is improved effectively and the ecological environment in the mine area is improved.
Description
Technical field
The present invention relates to the ecological recovery method of a kind of refuse dump vegetation, belong to the mine ecological restoration field.
Background technology
The refuse dump is that the discarded object that To Mining Development stays is stacked the place, be made of matrix such as hard, the stone that hardens, the grains of sand, general waste-rock yard Slope is than 1:1.3, mesa width 2.0m left and right, highly generally can be divided into 3-4 ladder according to the refuse dump stacking, about each stepped vertical height 20m.The refuse dump has not only taken a large amount of soils and farmland, has also destroyed simultaneously plant and ecoscape.Some mining areas have tied up a large amount of soils and farmland for a long time because of mining activity, cause the farmland underproduction or total crop failure, and part mining area water and soil loss, desertification are seriously.
China's main Mine Abandoned Land Reclamation Technique at present relates generally to the following aspects:
⑴ reclaim with the improvement of plant.Mainly the resistance of reclaiming with plant is improved, as carrying out Mycorrhizal by ectomycorrhizal fungi-inoculated or to seedling, perhaps inoculated with VA mycorrhizal fungi and azotobacter are simultaneously perhaps adopted the measures such as biobag that special-purpose planting given birth to glass or bank protection is used;
⑵ the base material improvement of abandoned mine land Subsided Reclamation Region.Comprise the physicochemical environment of improving matrix, need use a large amount of soil moved in to improve the originals to cover as the soil moved in to improve the original improved method; After utilizing rubbish and coal to burn, the ashes of (after generating) add NaOH as soil-repairing agent, are used for the technology of stabilizing heavy metal; Improve the methods such as mine tailing nutrient, moisture by adding the materials such as wormcast, water-loss reducer; Carry out base material improvement with red mud+CHARACTERISTICS OF TAILINGS SAND+excess sludge or phosphogypsum powder+activated sludge powder+paper pulp+water-loss reducer+Cosan+gummi arabicum pulveratum etc. as cladding material.
Yet, how can prior art or method spread is most important, this not only relates to the source of modifying agent, also will consider the difficulty of technology field conduct, the height of Financial cost, the ecological effect that will improve from the angle of sustainable development consideration of environment simultaneously.
Summary of the invention
The present invention be directed to existing mining area ecological environment and destroy problem serious and that be difficult to recover, provide a kind of and save soil, reduce the ecological recovery method of the refuse dump vegetation of ecological recovery cost.This method is to choose specific plant according to preferred arrangement, the diverse location of refuse dump to be carried out the vegetation plantation.
Realize that above-mentioned purpose is by the following technical solutions: the ecological recovery method of a kind of refuse dump vegetation, described method comprise sowing two aspects of the smooth and vegetation of refuse dump, and its concrete steps are,
(1) place is smooth:
A, adopt CHARACTERISTICS OF TAILINGS SAND to fill rubble space on domatic and plane, refuse dump, the height that is filled to the rubble exposed part is 5-15cm;
B, with the mountain skin soil of peeling off in mining process, rubble is covered, covered fully to rubble, thickness of earth covering is 20-30cm;
(2) plantation of vegetation:
A, the pouring place to surface, place mountain skin soil fully drenched;
B, plant different vegetation in the venue: the domatic top sowing in refuse dump herbaceous plant alfalfa, butch clover and eight treasures (choice ingredients of certain special dishes) red-spotted stonecrop, the domatic middle part sea-buckthorn of planting, the lower slope Seedlings of Black Locust of planting, the cotton class Climbing Plant of toe planting site, platform plantation locust tree;
Water every other day before the alfalfa on c, domatic top and butch clover emerge, and irrigate, the rear Routine Management of emerging; The vegetation Routine Management of other positions gets final product.
The implantation methods of diverse location vegetation is as follows:
A, domatic top: alfalfa and butch clover are adopted to fall apart and execute mode, and alfalfa is every 667m
2Sowing 1.2Kg seed covers mountain skin soil 3-4cm, and butch clover is every 667m
2Sowing 0.8Kg seed covers mountain skin soil 2-3cm; Eight treasures (choice ingredients of certain special dishes) red-spotted stonecrop root band Tu Tuo transplants, and the soil diameter that sticks together is 8-10cm, and spacing in the rows and line-spacing are respectively 0.3cm, and plum blossom-shaped is arranged, seedling age 2-3, and implantation depth is more than or equal to 0.3m;
B, domatic middle part and lower slope: sea-buckthorn and locust tree are bunch planting, and plum blossom-shaped is arranged, 2 strains of every cave, and the cave distance is 0.5m, seedling age 2-3, implantation depth is more than or equal to 0.3m; The long 10-15cm of nursery stock root;
C, toe: the spacing in the rows of the cotton class Climbing Plant in ground is 0.6m;
D, platform: locust tree is bunch planting, 2 strains of every cave, and the plum blossom-shaped layout, the cave distance is 0.5m, seedling age 2-3, the long 10-15cm of nursery stock root, implantation depth is more than or equal to 0.3m.
Mountain skin soil is the massif topsoil of peeling off in the outdoors iron ore recovery process.
CHARACTERISTICS OF TAILINGS SAND is that particle diameter is less than 300 purpose iron tailings.
Compare with existing situation, the invention solves the problem of iron tailings bulk deposition, reduced the usage amount of soil moved in to improve the original, reduce engineering cost; Domatic diverse location is planted different sections purpose plant in the refuse dump, adopt preferred arrangement, improve the emergence rate of vegetation and the survival rate of nursery stock, have obvious society, ecology and economic benefit, effectively improve the revegetation effect of refuse dump, improved mining area ecological environment.
Embodiment
The present invention will be further described below in conjunction with embodiment.
The ecological recovery method of this refuse dump provided by the present invention vegetation comprises sowing two aspects of the smooth and vegetation of refuse dump, and its concrete steps are,
(1) place is smooth:
A, adopt CHARACTERISTICS OF TAILINGS SAND to fill rubble space on domatic and plane, refuse dump, the height that is filled to the rubble exposed part is 5-15cm;
B, with the mountain skin soil of peeling off in mining process, rubble is covered, covered fully to rubble, thickness of earth covering is 20-30cm, and its best thickness of earth covering is 25cm;
