本文测定了厦门港海域表层沉积物36个站位样品中10种污染物的含量,并用Q型因子分析法用电子计算机编制程序对36个样品10个变量进行聚类分析,结果表明36个站位表层沉积物大体可分成两类,一类以有机质、硫化物、铅、铜、汞含量较多为其特征,此类沉积物大多粒度较细,处于较封闭环境,另一类以DDT、666含量较多,有机质、硫化物等含量较少为特征,此类沉积物大多处于较开阔环境且粒度较粗,计算结果较好地解释了各站位的污染情况。

In this paper, the content of 10 pollutants in 36 stations of surface sediments in Xiamen Harbor was measured. The cluster analysis of 10 variables in 36 samples was performed by computer program with Q-factor analysis. The results showed that 36 stations The surface sediments can be divided into two categories. One is the organic matter, sulfide, lead, copper and mercury content is more characterized by these features, most of these sediments smaller size, in a more closed environment, the other with DDT, 666, organic matter, sulfides and other content is less characterized, most of these sediments are in an open environment and coarse grain size, the calculation results better explain the pollution of the stations.
