对采自江西红壤地区的六株马尾松的圆盘年轮样及它们当年的根部土壤，进行Al，P，Fe，Co，Cu，Zn，Ba，Pb等元素含量分析。实测结果表明年轮元素含量的分布平均值C（Z）与当年根部土壤中元素含量的分布平均值C（Z）之间存在统计相关性，并满足对数线性相关模式：其中Z是元素原子序数，用以表征不同化学元素；统计回归系数a、b和元素、树种、气候因子以及土壤类型有关。因此，年轮元素含量时间（年份）序列C（Z，t；）可反映根部土壤中元素含量C’（Z，ti）的逐年变化，即再现环境的历史演变。
The elemental abundances of Al, P, Fe, Co, Cu, Zn, Ba and Pb in the annual rings of the six Pinus massoniana plants from the red soil area of Jiangxi Province and the root soils of the year were analyzed. The measured results show that there is a statistical correlation between the average C (Z) distribution of elemental abundance of annual rings and C (Z) of distribution of elemental contents in the root soils of the current year and satisfy the logarithmic linear correlation pattern: where Z is the elemental atom Ordinal number, used to characterize different chemical elements; statistical regression coefficients a, b and elements, tree species, climatic factors and soil types. Therefore, the sequence of annual element ages (years) C (Z, t;) can reflect the annual change of elemental content C (Z, ti) in the root soil, that is, the historical evolution of the reproduction environment.
