本文用树木元素富集系数（Ｔ／Ｓ）来研究南京栖霞山铅锌多金属矿区树木－土壤系统中元素的富集特性。结果表明，树木对土壤中Ｋ、Ｐ二个元素的吸收基本与树种和开矿活动关系不大。黑松对Ｃｒ、Ａｌ，马尾松对Ｍｎ、Ｐｂ、Ｃｏ、Ｎｉ、枫杨对Ｐ，刺槐对Ｍｇ、Ｎａ、Ｔｉ．栎对Ｚｎ、Ｃａ、Ｋ、Ｆｅ、Ｓｒ、Ｂａ、Ｖ，槐树对Ｃｕ均有最大的富集系数。黑松树龄对Ｃｏ、Ｋ、Ｚｎ含量和Ｃａ的富集系数有一定的影响。另外，Ｃｏ－Ｎｉ、Ｓｒ－Ｂａ的Ｔ／Ｓ曲线分别呈正相关，表现出这两组元素各自的地球化学共轭性。
In this paper, element enrichment (T / S) was used to study the element enrichment in the Qixiashan Pb-Zn polymetallic ore district. The results showed that the absorption of K and P in the soil by the trees was not related to the species and mining activities. Pinus massoniana Cr, Al, Pinus massoniana Mn, Pb, Co, Ni, Pterocarya stenoptera P, Robinia pseudoacacia Mg, Na, Ti. Quercus acutum had the largest enrichment coefficient for Cu, Zn, Ca, K, Fe, Sr, Ba, V and Cassia. The age of black pine had a certain effect on the contents of Co, K, Zn and Ca enrichment. In addition, the T / S curves of Co-Ni and Sr-Ba were positively correlated, respectively, showing the geochemical conjugation of the two groups of elements.
