矿山石漠化生态治理技术与工程应用

Ecological control technology and engineering application of mining rocky desertification

石漠化加速生态环境恶化,使水土流失,岩石裸露面积扩大,可利用土地面积减少,土壤养分大量流失,有的甚至伴随着严重的环境污染。石漠化已成为我国西南地区和矿区面临的生态地质环境问题之一。本文重点围绕矿山重金属污染土壤原位稳定技术,地表径流梯度拦截阻隔与净化技术和矿山石漠化植被生态恢复技术开展研究,并通过工程应用示范,旨在为矿山石漠化生态治理提供技术和实践支撑。

Rock desertification accelerates the deterioration of the ecological environment,causing soil erosion,expanding the exposed area of rocks,reducing the available land area,causing a significant loss of soil nutrients,and even accompanied by serious environmental pollution.R ock desertification has become one of the ecological and geological environmental problems faced by the southwestern region and mining areas in China.This article focuses on the in-situ stabilization technology of heavy metal contaminated soil in mines,the interception and purification technology of surface runoff gradient,and the ecological restoration technology of vegetation in mining rocky desertification.T hrough engineering application demonstration,the aim is to provide technical and practical support for ecological management of mining rocky desertification.
