摘要
为改善露天矿山开采地区基材条件,促进生态环境修复,以某露天矿山为例,开展对其开采活动作业区的生态环境修复研究。在明确该露天矿山概况条件后,文章提出一种通过基质改良、植被与微生物修复以及辅助修复措施实施的修复技术。通过对修复后研究区域的基材容重、孔隙度、酸碱度以及有机物质养分含量测定得出,各项指标均与修复前相比得到改善,并且均在标准要求范围内,实现了对该研究区的生态环境修复。
In order to improve the substrate conditions in the open-pit mine mining area and promote the restoration of the ecological environment,taking an open-pit mine as an example,the research on the restoration of the ecological environment in the mining operation area was carried out.After clarifying the general conditions of the open-pit mine,a remediation technology is proposed through matrix improvement,vegetation and microbial restoration,and auxiliary restoration measures.By measuring the bulk density,porosity,pH and organic matter nutrient content of the substrate in the study area after repair,it is found that all indicators have been improved compared with those before repair,and are all within the standard requirements,and the ecological environment restoration inthestudyareatheis realized.
