摘要: 在昌乐县采集了315份表层土壤样品,分析了其中As、Pb、Zn、Cd、Cr、Cu、Hg和Ni八种重金属元素的含量,采用单因子指数和内梅罗指数对土壤环境质量进行评价。单因子土壤环境质量评价结果表明,昌乐县土地环境质量总体状况良好,除镍元素以外,其它七项重金属指标均属清洁的,即达到I级土壤环境质量标准的土壤面积都占99.46%以上。土壤环境中镍的高风险含量,主要与地质背景有关,污染区集中分布在昌乐县中部的新近纪玄武岩分布区,岩性主要为玄武岩夹砂砾岩、粘土岩及硅藻土。内梅罗污染综合指数评价结果表明,昌乐县土地环境质量以Ⅰ级土壤环境质量标准的土壤为主,比例为53.83%,其次为II级、III级,分别占境域面积的22.62%、19.04%,IV级、V级土次之,分别占境域面积的3.91%、0.60%。其中,镍含量较高,属于污染最严重的因子,对内梅罗综合指数评价结果影响较突出,而其余七项重金属指标均属清洁的。

Abstract: In Changle County, we collected 315 topsoil samples, analyzed the content of As, Pb, Zn, Cd, Cr, Cu, Hg and Ni eight kinds of heavy metals, using single factor index and Nemerow index to evaluate the soil environmental quality. The evaluation results of single factor soil environmental quality showed that the overall condition of soil environmental quality in Changle County is good; except nickel, seven other heavy metals indicators are clean, i.e. soil area that reached grade I soil environmental quality standards accounted for more than 99.46%. The high-risk nickel content of soil environment is primarily related to geological background. Contaminated areas are concentrated in Neogene basalts distribution areas in central part of Changle County. Its lithology is mainly basalt with interlayer of conglomerate, claystone and diatomite. Nemerow pollution index evaluation shows that the quality of soil environment in Changle County is mainly grade I level of soil environmental quality standards, with ratio of 53.83%. Then grades II and III account for 22.62% and 19.04% of the domain area. Again grades IV and V account for 3.91% and 0.60 % of the domain area. Nickel content is relatively high, which is the most polluted factor affecting the Nemerow index evaluation results. The remaining seven indicators of heavy metals are clean.
