南方“稀土热”过后,原矿区尾砂堆积场黄砂一片,草木不生,成了不毛之地。江西省科学院生物资源研究所在稀土矿区进行土地复垦试验,现在那些矿区已收到当年种植、当年受益的效果,当年的砂丘已被繁茂的乔木、灌木及草本植物所覆盖。当年江西稀土矿区的环保措施仅是筑坝挡土,控制尾砂下泄,或先铺覆一层一定厚度的表土或客土,再种植植物,这样不仅费用高,而且又将破坏另一地表、得不偿失。江西省生物资源研究所在寻乌县选一矿区尾矿堆积场地,采用不 After the “Rare Earth Heat” in the south, the yellow sand of the tailings piled up in the original mining area is not made of raw materials and has become a barren land. The Institute of Biological Resources of Jiangxi Academy of Sciences conducted land reclamation tests in rare earth mines. Now those mines have already benefited from the planting of that year. The mound of that year was covered by lush arbors, shrubs and herbs. In Jiangxi Province, the environmental protection measures of rare earth mines in Jiangxi Province were just earth-embankment dam construction, tailings discharge control or top dressing of a certain thickness of topsoil or soliciting land before planting plants. This would not only be costly but also destroy another surface, Not worth the candle Jiangxi Institute of Biological Resources Xiuwu County selected a mine tailings accumulation site, the use of no
