摘 要：
对南京栖霞山矿区黑松与马尾松３０３个年轮样品中８个元素含量进行统计相关及群分析，发现Ｋ、Ｃａ、Ｍｇ、Ｐ在年轮中的富集及其相关性不受开采活动的影响，Ｃｕ、Ｐｈ、Ｚｎ、Ｍｎ的相关关系与露采或浅部坑采引起的地表塌陷有一定联系，Ｋ与Ｐ、Ｍｇ与Ｚｎ及Ｃａ与Ｍｎ是表征采矿地段的元素组合类型，Ｋ与Ｐ、Ｍｇ与Ｍｎ则为矿区外围地段元素的组合类型．

摘 要：
Correlative statistics and group analysis of 8 elements contents of 303 tree ring samples ofPinus thunbergii and Pinus massoniana at mining area of Xixia Mountain show that the enrichements of K, Ca, Mg and P in tree rings and their correlations are not influenced bymining activities, while the correlations among Cu, Pb, Zn and Mn are related to the landsurface subsidence in a certain extent, due to open mining or shallow pit mining. Themining sector is characterized by the combination types of K-P, Mg-Zn and Ca-Mn, andits surrounding area is characterized by those of K-P and Mg-Mn.
