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。

Abstract: Correlative statistics and group analysis of 8 elements contents of 303 tree ring samples of Pinus thunbergii and Pinus massoniana at mining area of Xixia Mountain show that the enrichements of K, Ca, Mg and Pin 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.

Key words: Polymetal mine, Element content of tree ring, Xixia Mountain, landscape pattern, ecological risk, spatial auto-correlation., geostatistical feature, temporal and spatial change
