树木年代学可用于估测环境变化对树木生长的影响。当一些基本假设有足够依据时,年轮是比较树木之间年轮的样式,辩认局部伪年轮和双年轮的历年。应用树木年代学进行资源调查可分为以下三类:(1)利用年轮确定年代可形成一个准确的历年,环境变化而使树木致死或由某些因素显著影响 Tree chronology can be used to estimate the effect of environmental changes on tree growth. When some of the basic assumptions are sufficiently substantiated, the annual rings compare patterns of annual rings between trees, identifying the calendar years of local pseudo-annual rings and bi-annual rings. The application of tree geochronology resources survey can be divided into the following three categories: (1) the use of annual rings to determine the age can form an accurate calendar year, the environment caused by the death of trees or significantly affected by some factors
