摘　　要：针对矿区废弃地生态修复问题,采用多植物混种、边坡治理及综合绿化等理论方法,对山西太原某矿区进行了为期1年的生态修复技术研究。实验结果显示,植被覆盖率显著提升至85%,重金属Cd含量从2.5 mg/kg降至1.3 mg/kg,土壤pH值逐渐降低,从8.2降至7.4。这表明土壤中的酸性物质在逐渐释放或土壤修复措施对土壤酸碱度有所调节,土壤稳定性及生物多样性指数均得到明显提升。设计的综合性生态修复技术有效改善了矿区的生态环境质量,并显著提升了景观美学效果。该技术不仅为矿区废弃地的生态修复提供了新的解决方案,也为实现矿区可持续发展和生态平衡提供了科学依据。A one-year ecological restoration technology study was conducted on a mining area in Taiyuan,Shanxi Province,using theoretical methods such as plant intercropping,slope treatment,and comprehensive greening to address the issue of ecological restoration of abandoned land in mining areas.The experimental results showed that the vegetation coverage rate significantly increased to 85%,the heavy metal Cd content decreased from 2.5 mg/kg to 1.3 mg/kg,and the soil pH gradually decreased from 8.2 to 7.4.This indicates that acidic substances in the soil are gradually released or soil remediation measures are regulating the soil pH.The soil stability and biodiversity index have been significantly improved.The comprehensive ecological restoration technology designed effectively improved the ecological environment quality of the mining area and significantly enhanced the aesthetic effect of the landscape.This technology not only provides a new solution for the ecological restoration of abandoned land in mining areas,but also provides a scientific basis for achieving sustainable development and ecological balance in mining areas.
