Mine restoration ecological planning method based on geographic information system

Abstract

The invention discloses a mine restoration ecological planning method based on a geographic information system. The mine restoration ecological planning method comprises the following steps: S1, geological investigation: a step of collecting and arranging related data of a mining wasteland, carrying out visual management on the mining wasteland in combination with GIS, and reconstructing a green natural landscape. According to the invention, the steps of geological investigation, establishment of a water storage system, soil reclamation, soil remediation, livestock and poultry breeding, dredging of a water flow channel, vegetation recovery and the like are successively carried out on a mine, so the soil quality of degraded mine soil is effectively improved; meanwhile, weeds are sowed in the degraded mine, so the fertility of the soil is increased, and the nutrient and fertilizer environment required by vegetation coverage in a later period is facilitated; through livestock and poultrybreeding, income increasing can be achieved, and the ecological environment of the mine can be greatly improved; and compared with a mine repairing method in the prior art, the method provided by theinvention is more complete, more reasonable, higher in economic benefit and worthy of application and popularization.

Description

technical field [0001] The invention relates to the technical field of mine restoration, in particular to an ecological planning method for mine restoration based on a geographic information system. Background technique [0002] After the stone or metal mine is mined, the abandoned stone or associated stone is often backfilled to the mining area. If no measures are taken to deal with it, it will not only be unfavorable to the restoration of the landscape environment, but also under the effect of long-term weathering and rain impact, it will induce The main cause of mudslides is a serious safety hazard. [0003] In the prior art, there are mainly three methods for repairing finished mines. First, equipment solidification, that is, using mesh equipment to solidify finished mines. This method is not conducive to the restoration of the mine landscape environment. Second, foreign soil landfill, that is, use foreign soil to fill mines and then plant green plants. This method requ...

Problems solved by technology

[0002] After the stone or metal mine is mined, the abandoned stone or associated stone is often backfilled to the mining area. If no measures are taken to deal with it, it is not only not conducive to the restoration of the landscape environment, but also under the effect of long-term weathering and rain impact, it will induce The main cause of mudslides, there are serious safety hazards

[0003] In the prior art, there are mainly three methods for repairing the finished mining mine. First, the equipment is solidified, that is, the netted equipment is used to solidify the finished mine. This method is not conducive to the restoration of the mine landscape environment.

Second, foreign soil landfill, that is, use foreign soil to fill mines and then plant green plants. This method requires a relatively high price, and in dry and early areas, foreign soil is deserted, causing new ecological problems. Restoration General effect

Third, aerial sowing of grass or tree species is simple and cheap, but in Northwest China, in the environment of perennial sandstorms and drought, after the seeds are sown, the enzyme activity decreases, resulting in the survival rate and survival rate of aerially sown grass or tree species. The rate is generally low, and repeated replanting is required every year, and the continuity of restoration is poor
