摘要

柿竹园矿区有色矿产资源丰富,矿山地质环境问题严峻,土壤重金属污染尤其突出。本文使用数理统计分析等方法对研究区土壤环境介质中的重金属元素的组分含量和空间分布特征进行分析。通过组分含量特征分析可知:土壤重金属呈正偏离态分布,Pb、Cd、As、Cu、Zn属于空间强变异,Cr、Hg属于空间弱变异; Cd-Zn、Cu-As、CuZn、Cu-Cd、Cd-As相关性显著,表明土壤Cd、Zn、As和Cu主要受矿山开采活动控制。通过空间分布特征分析可知:矿集区易向土壤中释放Ni、Cu、Cd、Zn、Pb和As并且输入量较大,尾砂库、矿集区和选矿厂向土壤中释放Cr的能力较小;尾砂库、矿集区和选矿厂没有向土壤中释放Hg。研究结果对柿竹园矿山流域的水资源、土地资源、矿山资源及生态资源的开发与保护具有借鉴意义。
        The Shizhuyuan mine area has abundant nonferrous metal mineral resources,but with severe mine geological environmental issues,especially the soil heavy metal pollution. The paper through mathematical statistics method etc. carried out analysis of study area heavy metal element component contents and spatial distribution features in soil environmental media. From components content features analysis can be seen that the soil heavy metals present normal skewed distribution,Pb,Cd,As,Cu and Zn belong to spatially strong variation,while Cr and Hg belong to spatially weak variation. Obvious correlations between Cd-Zn,Cu-As,Cu-Zn,Cu-Cd and CdAs have shown that Cd,Zn,As and Cu in soil are mainly controlled by mining activities. Through spatial distribution features analysis can be seen that in ore concentrated area can easily release Ni,Cu,Cd,Zn,Pb and As into soil with larger amount,while from tailings disposal area,ore concentrated area and concentration plant have smaller Cr release ability to soil and without any Hg release into soil. The study has reference significance for Shizhuyuan mine drainage area water,land,mine and ecological resources exploitation and protection.
