摘　　要：为减小石料矿山开采过程中废弃石粉对生态环境造成的影响,实现废弃石粉资源化利用,该文以生态修复学理论为基础,废弃石粉最大限度消纳为出发点,以废弃花岗岩碎石粉为研究对象,通过比较不同石粉掺量(石粉∶黏土体积比为0∶1、1∶1、2∶1、3∶1)的人工土壤基质的物理特征,以及对植物生长指标等方面影响,筛选出石粉与黏土体积比为1∶1(占基质总体积70%),APAM 10 ml,稻壳∶木纤维∶绿肥体积比为2∶1∶2(占基质总体积30%)的土壤基质重构最优方案,构建了边坡修复—植被恢复联合型废弃石粉消纳新模式。有利于节约土地资源、美化生态环境,并带来了一定的经济效益,为研究废弃石粉作为改良土壤掺合料提供了理论依据和实践参考。To reduce the ecological impact caused by waste stone powder during stone mining and to promote its resource utilization,this study is based on the theory of ecological restoration and aims to maximize the consumption of waste stone powder.Using waste granite stone powder as the research object,the study compares the different stone powder contents(stone powder-to-clay soil volume ratios of 0∶1,1∶1,2∶1,and 3∶1)on the physical characteristics of artificial soil matrix,and its influence on plant growth indexes,etc.The optimal soil matrix reconstruction scheme is determined as a stone powder-to-clay soil volume ratio of 1∶1(accounting for 70%of the total volume of the matrix),APAM 10 ml,and the rice husk:wood fiber:green manure volume ratio of 2∶1∶2(accounting for 30%of the total volume of the matrix).Based on this,a new model for waste stone powder consumption combining with slope restoration—vegetation recovery is constructed.It is beneficial to conserve land resources,enhance the ecological environment,and generate economic benefits.It also provides a theoretical basis and practical reference for using waste stone powder as soil amendment.
