用富集系数研究了相同土壤类型上生长的不同树种，不同土壤类型上生长的同一树种，及不同土壤类型上生长的不同树种对１８种元素的富集情况．结果表明，黄棕壤上生长的悬铃木对元素Ｐ的富集系数最大，而马尾松对元素Ｃｄ的富集系数最大；对于生长在不同土壤类型上的马尾松，则由于土壤本身偏酸性而造成黄棕壤和红壤上生长的马尾松对大部分元素有较高的富集系数；从不同土壤类型上生长的不同树种对元素的富集系数来看，元素Ｐ的差异最大，红壤、黄棕壤上生长的马尾松对元素Ｃｄ的富集系数远远大于其它土壤类型上生长的各树种（本文所讨论范围内），过渡元素及原子序数较大的Ｂａ、Ｐｂ两个元素的富集系数则无明显差异
The enrichment coefficients were used to study the enrichment of 18 species by different tree species grown on the same soil type, the same tree species grown on different soil types, and different tree species grown on different soil types. The results showed that the genus Platanus grown on yellow-brown soil had the strongest enrichment coefficient for element P and the mass-concentration coefficient of Masson’s pine for the elemental Cd, and the mass-produced biomass for masson pine growth on different soil types Masson pine and Pinus massoniana grown on yellow brown soil and red soil had higher enrichment coefficient for most of the elements. In terms of enrichment coefficient of different tree species grown on different soil types, the element P had the largest difference, The enrichment coefficient of elemental Cd by P. massoniana grown on soil was much larger than that of other tree species grown in other soil types (discussed in this paper), and the enrichment coefficients of transition elements and Ba and Pb with larger atomic numbers No significant difference
