矿山固体废弃物种植混合土配制方法及生态修复实效

矿山固体废弃物资源化利用与处置一直是矿山与矿业领域关注和科学研究的重点。为满足矿山废弃地复垦与生态修复之需要，在山区自然混合土与植被特征调查研究的基础上，提出了矿山固体废弃物种植混合土及其配制方法。同时，通过了盆栽试验和地栽试验研究，结果显示：利用矿山固体废弃物与好土（细粒土），按本法能够很容易配制出适合植物生长的矿山固体废弃物混合土基质；利用这种矿山固体废弃物种植混合土进行矿山废弃地复垦与生态修复，不仅可以大量地消耗与处置矿山固体废弃物，而且能够快速地实现矿山生态恢复，较有效地防止泥石流、水土流失、环境污染等环境问题，其生态效益、社会效益和经济效益均较显著。

Preparation of Mine Solid Waste Mixed Soil for Plants and Its Ecological Restoration Effect

The utilization and disposal of mine solid waste resource is the focus of scientific research in the field of mine and mining. In order to meet the needs of mine abandoned land reclamation and ecological restoration,a method for the cultiva-tion of mixed soil and its preparation are put forward on the basis of the investigation of natural mixed soil and vegetation char-acteristics in mountainous areas. At the same time, pot experiment and pot experiment research showed that the solid waste mixed soil matrix can be easily prepared for growing plants with the solid waste and good soil ( fine grained soil) by this meth-od;Usage of the mixed soil for waste land reclamation and ecological restoration not only disposes a large number of mine solid waste,but also quickly achieves mine ecological recovery and effectively prevents the debris flow,soil erosion,environmental pollution and other environmental problems,with remarkable ecological benefits,social benefits and economic benefits.
