摘要
太原市土壤的研究还处于起步阶段,尚缺乏系统的研究和探讨。基于因子分析法分析研究太原市土壤重金属污染类型及污染来源,在面积性土壤测量基础上,采用城市土壤单点样采集方法,通过测试获得了城市表层土壤中重金属元素(As、Cd、Hg、Pb、Cr、Ni、Zn、Cu)的含量数据;应用统计数手段及处理软件,采用因子分析法对太原市土壤化探数据进行详细分析研究;结合太原市工企分布情况,对比因子分析中的六个主因子,进行整理分析;研究结果充分反映出太原市作为一个典型的重化工基地和燃煤城市的污染特点,表明太原市土壤重金属污染的主要来源有四个方面,即:工矿企业污染源,燃煤污染源,交通污染源,商业活动和居民生活污染源等。
The research of the soil is at the starting stage and still lack systematic research and discussion in Taiyuan. This paper analyses the soil heavy metal in Taiyuan and it＇s pollution types and sources based on the factor analysis. On the foundation of measure in the area soil, adopting the urban simple point soil form methods of gathering, and by analyzing the experimental results of soils sample in Taiyuan city, we obtain the content data of the heavy metal elements （As, Cd, Hg, Pb, Cr, Ni, Zn, and Cu）; Factor analysis of soil geochemistry data is analysed and studied in detail by using statistics means and the software. Combined the distribution situation of worker＇s enterprise, and contrasted six host factor of factor analysis, it is sorted and analyzed. The research result of factors analysis can sufficiently reflects Taiyuan as a typical heavy pollution characteristic of chemical base and coal-fired city. Finally it indicates there are four respects in main sources of soil heavy metal pollution, which involve the pollution sources of industrial and mining enterprises, coal-fired pollution sources, traffic pollution sources, business activity and resident＇s life pollution sources, etc.
