| 摘 要： | 以石家庄城市土壤为对象,采用单因子指数法和尼梅罗综合指数法对土壤重金属的环境质量及污染特征进行评价,并采用Hakanson提出的潜在生态危害指数法对土壤中重金属的潜在生态危害进行评价。结果表明,重金属污染程度依次是Cd>Zn>Hg>Cr>Ni>Pb>Cu>As,其中Cu、Pb、As都处于清洁安全状态,Ni绝大部分样点处于清洁安全状态,只有0.45%处于警戒状态,Cd、Hg、Zn、Cr元素都出现污染,其中Cd污染面积最大,达到1.36%;综合污染评价土壤环境整体良好,清洁、安全、警戒、污染土壤面积比例分别为65%、31.82%、2.73%、0.45%,其中警戒及污染土壤面积为3.18%,其形成可能与工业生产及人类活动有关;各重金属元素中,产生潜在生态危害的重金属主要是Hg、Cd,已分别达到强潜在生态危害和中等潜在生态危害水平,其余重金属均为轻度潜在生态危害,综合考虑多种重金属的潜在生态危害性,其轻微生态危害、中等生态危害、强生态危害、很强生态危害的百分比分别是38.6%、53.2%、7.3%、0.9%,整体表现为中等潜在生态危害。

| Abstract: | With the urban soil of Shijiazhuang city as a target,this essay evaluates the environmental quality of soil heavy metals and pollution characteristics by adopting the single factor index method and Nemerow comprehensive index method.Besides,the potential ecological hazard index suggested by Hakanson is used to assess the ecological hazard of heavy metal in urban soil.The results show that the elements,according to the pollution degree of heavy metal,are followed by the order of Cd>Zn>Hg>Cr>Ni>Pb>Cu>As.Most ... |
