A Function of Standardization Induced from Tree-ring Analysis of Picea glehnii

对日本北方北海道的赤松（Piceaglehnii）、日本本州中部的扁柏（Chamaparis obtusa）和柳杉（Cryptomeria japonica）的年轮进行了分析，发现它们适合于年轮学分析。本文的目的是为暨南树木年轮学的标准化寻找一种功能。通过对高径拟合器（周期<5年）进行三阶多项式指数化处理，建立了去除生长趋势的标准化函数。利用时间序列的分析结果，比较了同一地点不同树种和不同地点同种树种的年轮时间序列的同步特征。不同树高（基部到树冠）的时间序列具有很高的相关性。此外，还对立地年代学对及其间距进行了Student-t分析，计算出云杉的距离约为130 km，柏树约为350 km，雪松约为200 km。同时，通过对日本546个样本的29个年表时间序列的交叉分析，得到了树轮时间序列的同时性特征，并对不同地点的树轮时间序列变化的同时性特征进行了检验，从而得到了统一的有用的交叉数据。因此，云杉，柏树和雪松似乎产生一个很有前途的指数，在日本的树木年表建设。

Tree-ring samples from akaezomatsu (Picea glehnii) in northern Hokkaido, hinoki (Chamaecyparis obtusa) and sugi (Cryptomeria japonica) in central Honshu of Japan were analyzed and found suitable for dendrochronologic analysis. The purpose of this paper is to find a function of standardization for dendrochronology in Janan. A standardization function for the removal of thegrowth trend was created by treating the high-path fitger (period<5 year) with third order polynomial indexing. This was accomplished by utilizing analyzed results of the time series.The simultaneous characteristics of the tree-ring time series was compared between various species obtained from the same sites, and between the same species from different sites. The time series of different height of a tree (base to crown) was shown to have a high correlation. In addition, Student-t analysis of site chronology pairs and their distance apart were completed, It was calculated to be approximately 130 km in spruce, 350 km in cypress, and 200 km in cedar. Also, simultaneous characteristics in tree-ring time series were obtained in cross-dated analysis of 29 chronology time series from 546 samples in Japan.The simultaneous characteristics of the variation of tree-ring time series were examined in various sites and this resulted in a uniform and useful cross-date. Thus, spruce, cypress and cedar appear to produce a promising index for dendrochronology-building in Japan.
