基于酸性矿山土壤产酸潜力分析的精准修复技术

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。本文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。

Precision remediation technology based on acid production potential analysis of acid mine soil

In the ecological restoration of acid mining, 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.
