文摘内容 Element contents of tree rings and soils near tree roots collected from Deodar cedar (Cedrus deodara (Roxb.) G.Don) and Masson pine(Pinus massoniana lamb).were determined to study the relationship between the angular distribution of element contents in tree rings and the environmental information.The chemical composition and properties of soil are very much cmoplicated,which leads to the non-uniform distribution of the element contents in tree rings.The statistical multi-varialbe regression method was used to get the information of the tree-centered distribution of element contents in the environment(soil),(C'),C'(Z,θj),from the distribtuion of element contents in tree rings(C),C(Z,θi),which depends on the plane azimuth angle(θi),i.e.,C=C(Z,θi),where Z is the atomic number of the element,with a satisfactory result though this study is only a primary one。
