对广州市南沙区榄核河沉积物中5种典型重金属（Cu、Zn、Pb、Ni 和 Cr）的含量水平进行分析，并在此基础上对各元素进行相关性分析和地累积指数评价。结果表明，榄核河沉积物重金属污染严重，5种金属元素的浓度和介于3710.38~11143.02 mg/kg 之间，各金属浓度高到低为 Zn、Cu、Ni、Cr、Pb；Cu、Ni 和 Cr 它们3者之间两两相关性显著，表明这3种金属元素来源相同或相近；5种重金属元素的富集程度由高到低为 Cu、Ni、Zn、Pb、Cr，沉积物总体呈现出以 Cu 为主的多种重金属复合污染特征。
對廣州市南沙區欖覈河沉積物中5種典型重金屬（Cu、Zn、Pb、Ni 和 Cr）的含量水平進行分析，併在此基礎上對各元素進行相關性分析和地纍積指數評價。結果錶明，欖覈河沉積物重金屬汙染嚴重，5種金屬元素的濃度和介于3710.38~11143.02 mg/kg 之間，各金屬濃度高到低為 Zn、Cu、Ni、Cr、Pb；Cu、Ni 和 Cr 它們3者之間兩兩相關性顯著，錶明這3種金屬元素來源相同或相近；5種重金屬元素的富集程度由高到低為 Cu、Ni、Zn、Pb、Cr，沉積物總體呈現齣以 Cu 為主的多種重金屬複閤汙染特徵。

The contents of heavy metals Cu, Zn, Pb, Ni and Cr in sediment of Lanhe River were measured. On the basis, the correlating analyse and the indexes of geography accumulation of five heavy metal elements were analyzed. The results indicated that the sediment of Lanhe River had been seriously polluted by heavy metals. The total amount of five heavy metal elements reached 3 710.38~11 143.02 mg/kg and it showed the order of Zn, Cu, Ni, Cr, Pb. Correlation analysis among Cu, Ni and Cr showed the significant relation to each other, so these three heavy metal elements had a greater possibility to have come from the same source. The order of the enrichment degree of five heavy metals was Cu, Ni, Zn, Pb, Cr. The pollution characteristic of multi-metals in research region was mainly related to Cu.
