Ecological Remediation of the Abandoned Area in a Quarry in Northern Guangxi

矿产资源作为一种重要的自然资源，对其开采利用，为国民经济的快速腾飞贡献了有力的物质基础，但在矿山无序、大肆开采过程中也产生了一系列严重的环境问题，如矿山地质灾害频发、地貌景观退化和地下含水层破坏等，严重威胁到人民的生命财产安全，故需迫切解决。文章基于此，对桂北某废弃矿山进行生态修复，修复区总面积16.0221 hm2，秉持“宜农则农，宜水则水，宜建则建”的原则，将1#采空区底盘总面积7.0220 hm2修复成体育用地，可以很好地解决罗锦镇人均体育用地不足的现状，并且能满足“全民健身”号召的用地需求；2#采空区底盘总面积2.8371 hm2复垦成公园与绿地，同样解决罗锦镇人均公园绿地面积低于平均水平的现状，为居民提供一个休闲观光的好去处；将1#采空区边坡总面积4.9480 hm2、2#采空区边坡总面积0.5254 hm2分别复垦成其他林地和其他草地，进行矿山地貌景观的重塑，与周边的自然景观相协调；矿山道路总面积0.9376 hm2，复垦成农村道路，方便大家出行。方案既对矿山破坏严重区进行了植被重建，还将土地进行再利用，很好地缓解了罗锦镇人地紧张的矛盾。As an important natural resource, the exploitation and utilization of mineral resources has contributed a strong material basis for the rapid take-off of the national economy. However, a series of serious environmental problems have also arisen in the process of disorderly and wanton mining in mines, such as frequent geological disasters in mines, degradation of geomorphological landscapes and destruction of underground aquifers, which seriously threaten the safety of people’s lives and property. Therefore, it is urgent to solve them. Based on this, this paper carries out ecological restoration on an abandoned mine in northern Guangxi. The total area of the restoration area is 16.0221 hm2. Adhering to the principle of “agriculture is suitable for agriculture, water is suitable for water, and construction is suitable for construction”, the total area of the 1 # goaf chassis is 7.0220 hm2. Repairing into sports land can well solve the current situation of insufficient per capita sports land in Luojin Town, and can meet the land demand called for by “national fitness”; the total area of 2 # goaf chassis is 2.8371 hm2 reclaimed into parks and green spaces. It also solves the current situation that the per capita park green space area in Luojin Town is lower than the average level, and provides residents with a good place for leisure and sightseeing. The total area of the 1 # goaf slope is 4.9480 hm2, and the total area of the 2 # goaf slope is 0.5254 hm2, which are reclaimed into other woodlands and other grasslands to reshape the mine landscape and coordinate with the surrounding natural landscape. The total area of the mine road is 0.9376 hm2, which is reclaimed into a rural road to facilitate everyone’s travel. This scheme not only carried out vegetation reconstruction in the area with serious mine damage, but also reused the land, which well alleviated the contradiction between people and land in Luojin Town.
