树木年轮的结构与气象因素的关系,已引起研究者们的关注。环境条件对树木生长量影响的活跃时期现已查明。为了制订一个由于气候条件的变化而长期可以测定树木生长量的模式,需将树木连年生长量的平均值或总生长量值与同期主要气候因素的平均值,特别是此一时期的总降水量进行计算与比较是有意义的。
The relationship between the structure of tree rings and meteorological factors has attracted the attention of researchers. The active period of environmental conditions affecting tree growth has now been identified. In order to develop a model for long-term determination of tree growth due to changes in climatic conditions, the average value of annual tree growth or total growth and the average value of main climate factors over the same period, especially the total precipitation during this period It makes sense to calculate and compare.
