摘要： 黄河流域存在着两类不同的树木年轮取样环境。在典型的取样环境中,树木生长多遵循缓慢递减的规律,作生长量订正时,可采用传统的树木年轮学订正方法。在非典型的取样环境中,树木生长形式较为复杂,可引进新的分析途径,包括多项式函数和样条函数的应用。随样本环境的不同,各类订正分析的可适用性亦有差异。

关键词: 取样环境, 生长量订正

Abstract: There are two kinds of sampling environments for dendrochronological study.At the typical environment,the tree growth may basically follow the regulation of progressive decrease with the increased age .The standardization could be adopted by the classical approach for tree-growth reduction in dendrochronology However,the tree-growth pattern seems more complex at the non-typical environment,where the climate is warmer and wetter The approach,including the application of polynomial and/or spline functions,could be con-sidered With different sampling environments,the applicabilities for various reduction functions have been analysed in this paper

Key words: sampling environment, tree-growth reduction
