对黄河洽川湿地进行样品采集，采用国标法消化，测定了湿地土壤中Pb、Cd、Cr、Cu、Zn和 Mn的含量，利用潜在生态危害指数法评价土壤重金属的潜在危害程度。结果表明该湿地属于很强生态危害，主要原因是Cd污染严重超标。
對黃河洽川濕地進行樣品採集，採用國標法消化，測定瞭濕地土壤中Pb、Cd、Cr、Cu、Zn和 Mn的含量，利用潛在生態危害指數法評價土壤重金屬的潛在危害程度。結果錶明該濕地屬于很彊生態危害，主要原因是Cd汙染嚴重超標。

Abastract:The soil samples were collected from Hechuan wetland and digested by the national standard meth-od.The contents of Pb、Cd、Cr、Cu、Zn and Mn were detected and the potential ecological risk was estimated by the The potential ecological risk index.The result shows the wetland was seriously ecological hazarded.The main cause was that the content of Cd Seriously exceed the standard.
