摘　　要：采用火焰原子吸收法对黄河湿地(渭南市)表层土壤样品中的5种重金属元素含量进行了测定,所采集土壤中5种(Zn、Cr、Pb、Cu、Ni)重金属含量分别为:42.17~72.59、71.52~89.27、29.25~48.33、33.53~65.41、52.77~73.67mg·kg^(-1),其中Cr、Pb、Cu、Ni的含量均高于陕西省土壤环境背景值,污染分析表明,Cr、Pb处于轻污染水平,Cu、Ni处于中污染水平,Zn处于无污染水平,研究结果可对渭南市域内黄河湿地重金属污染防治和治理提供理论支持。The concentration of(Zn、Cr、Pb、Cu、Ni)wetland soil heavy metals in Weinan Yellow River were investigated by flame atomic absorption spectrometry,the result showed that heavy metal concentration of this region were 42.17~72.59、71.52~89.27、29.25~48.33、33.53~65.41、52.77~73.67mg·kg^(-1)respectively,the average content of Cr、Pb、Cu、Ni all exceeded background values of soil environment in Shaanxi Province,Cr、Pb were in light pollution,Cu、Ni were in moderate pollution,Zn was no pollution,The result provided inferences for wetland heavy metal pollution treatment.
