模糊数学对哈尔滨市新老工业区土壤重金属污染对比研究

摘要

Taking the soil heavy metal pollution in the old and new industrial zones in Harbin as a research subject, the contents of 6 heavy metals (Cu, Pb. Zn, Cd, Cr, Ni) in the primary soil are measured and analysed, and a comparison of the soil heavy metal pollution between the old and new industrial zones is made by using comprehensive identification fuzzy theory. It is shown shows that, compared with the background value of the soil of Song-Nen Plain, the heavy metal pollution in the both zones is much more serious. The soil environmental qualities for the old industry zone and the new industrial zone are Level III and Level II respectively. This study intends to show the different influence of social economy development on soil environment, so as to provide a scientific solution for a reasonable arrangement of Harbin industrial zones and soil heavy metal antipollution.%以哈尔滨市新老工业区土壤重金属污染为研究对象,对新老工业区土壤中的Cu、Pb、Zn、Cd、Cr和Ni等6种重金属元素进行了分析测定,采用模糊数学模型对新老工业区土壤重金属污染进行对比研究.研究结果表明,对照松嫩平原土壤背景值,研究区域重金属污染较严重,老工业区土壤环境质量为Ⅲ级,新兴工业区为Ⅱ级.该研究力图反映经济社会的发展对土壤环境不同的影响,为哈尔滨市工业区合理布局及土壤重金属防控提供科学依据.
