摘　　要：针对酸性矿山生态修复中,土壤基质改良材料精准添加量的问题。以广东某金属矿山废弃地为研究对象,基于土壤产酸潜力的分析,采用“原位土壤基质改良+直接植被”技术对其进行综合治理,同时通过NAG-pH酸化快速预测技术,高效评估土壤的潜在产酸量,从而精准计算土壤原位改良材料的添加量,使土壤改良效果长期有效,为后期实现稳定、安全、自维持的植被系统奠定坚实的基础。In the ecological restoration of acid mining,aim to solute the problem of accurate amounts of soil matrix improvement materials,this article used an abandoned land in a metal mine in Guangdong as the research object.Based on the analysis of soil acid potential,it uses the"improvement of the in-situ soil matrix+direct vegetation"technology to comprehensively govern it.The potential acid production of soil,thereby accurately calculating the addition of soil in situ improvement materials,so that the soil improvement effect is effective for a long time,laying a solid foundation for the stable,safe,and self-maintained vegetation system in the later period.

关 键 词：历史遗留矿山 矿山治理 土壤原位基质改良 直接植被 酸性
