生态环境与保护, 2020 矿山在关闭过后,会遗留大面积矿山废弃地,这些废弃地不仅会受到不同程度的损坏,甚至如果不能得到有效管理与修复还会影响生态环境,较为严重的甚至会危害人们的生命安全。因此必须要通过修复、重建、复垦等方式来改善矿山生态环境,避免因矿山环境受到破坏而造成严重生态问题。本文主要对矿山生态修复工程以及技术措施进行分析研究。

建筑技术研究, 2020 在当前社会经济的推动下,社会各个领域对矿产资源的需求量在不断提升,而且矿山开采的强度也在日益提升。然而,由于矿山能源开采完成后,会产生大量矿山废弃地,影响当地的生态系统,较为严重的甚至还会危害人类的身体健康,需要得到社会各界的广泛重视。因此,文章针对废弃矿山的露天采坑、破损山体、土地占损等地质环境问题,提出了废弃矿山地质环境保护与生态修复的对策,以期为有关部门制定水土保持规划提供参考。

Shuitu Baochi Xuebao, 2017 为探讨不同植物种植模式对矿山废弃地土壤肥力快速改良的效果，选取8种典型的植物种植模式（黑麦草、草木樨、沙打旺、小冠花、紫穗槐、紫穗槐+小冠花、紫穗槐+黑麦草和草木樨+黑麦草）。通过野外土壤采样与室内养分测定并结合主成分分析方法，对不同植物及种植模式下的土壤肥力进行了相关分析。结果表明：不同种植模式均能较好改善土壤水分状况，土壤含水率平均值比对照高8.7%；不同种植模式下土壤含水率随着土层深度的增加，总体呈增加—减少—增加—稳定发展趋势；植物对土壤蓄水保水效果的改良主要体现在0—40 cm的土层中 ...
