摘　　要：指出了白龟山湿地沉积物中Cd、Pb、Cr、Cu、Zn等重金属元素含量相关性较高,相关系数在0.9左右,相关性高的达到0.96,说明了它们具有同源性;Mn和Ni元素与其它重金属元素之间基本没有相关性,说明这两种重金属元素的来源具有自己的独立性。各元素的空间分布特征表明:Cd、Pb、Cr、Cu、Zn等5种重金属元素的含量分布人为影响较大,主要的污染源是鲁山污水处理厂,其次是姚孟电厂;Ni的空间分布特征指示了在澎河上游可能存在Ni的污染源;而Mn元素基本上没有人为因素的影响。Sediment samples analysis results showed that there was a relatively high correlation among Cd, Pb, Cr, Cu and Zn in Baiguishan sediments, and the correlation coefficients was about 0.9, with some up to 0.96, suggesting that these heavy mental elements were homologous; that Mn and Ni had almost no correlation with mentioned elements, suggesting the two elements had their own independence. According to spatial distribution characteristics of elements, Cd, Pb, Cr, Cu and Zn shared the same content distribution, and were impacted by anthropogenic factors, and the pollution were mainly derived from Lushan sewage treatment plant and Yaomeng power plant; spatial distribution characteristic of Ni suggested the possible existence of Ni pollution source in upper Peng River; while Mn showed no contribution from anthropogenic source.
