| Abstract: | In order to investigate the relationship between the attach of local disease and some trace elements from the biogeochemical point of view, we studied the trace elements in the tree ringsThe contents of 12 chemical elements, i.e., Mo, Cu, Si, Ba, Zn, Mg, Cr, B, Mn, Fe. P, Pb, in 51 rings of 4 trees of Populus davidiana, divided into 2 groups, were determined by emission spectrograph.The results of analysis show that the annual variations of some trace elements in the tree rings, which should closely connect... |
