Abstract

ABSTRACT Because of the eccentric radial growth for shrubs, climatic signals recorded by their ring-width series tend to be distorted. We hypothesized that measured Basal Area Increment (BAI) can overcome such a weakness. We used the desert shrub Zygophyllum xanthoxylum, with eccentric radial growth to test this hypothesis. RWI (mRWI) and BAI standard chronologies were established based on the ring-width data. Then, we converted BAI into RWI and created a transformed RWI (tRWI) standard chronology. Both BAI and tRWI showed higher correlation with climate records than mRWI, although their correlation coefficients were not significantly different from each other. Based on the comparison between tRWI and mRWI chronologies, mRWI overestimates the radial growth of Z. xanthoxylum caused by eccentric form. BAI can be applied to increase accuracy in dendrochronological studies for shrubs with eccentric growth.

利用基底面积增量校正偏心生长环——以西北沙漠灌木为例

摘要由于灌木径向生长偏心，其环宽序列记录的气候信号往往失真。我们假设测量的基底面积增量（BAI）可以克服这种弱点。我们使用了具有偏心径向生长的沙漠灌木Zygophyllum xanthoxylum来检验这一假设。根据环宽数据建立了RWI（mRWI）和BAI标准年表。然后，我们将BAI转换为RWI，并创建了一个转换后的RWI（tRWI）标准年表。BAI和tRWI与气候记录的相关性均高于mRWI，尽管它们的相关系数彼此没有显著差异。根据tRWI和mRWI年表的比较，mRWI高估了由偏心形态引起的黄木的径向生长。BAI可用于提高偏心生长灌木的树木年表研究的准确性。

期刊介绍： Tree-Ring Research (TRR) is devoted to papers dealing with the growth rings of trees and the applications of tree-ring research in a wide variety of fields, including but not limited to archaeology, geology, ecology, hydrology, climatology, forestry, and botany. Papers involving research results, new techniques of data acquisition or analysis, and regional or subject-oriented reviews or syntheses are considered for publication. Scientific papers usually fall into two main categories. Articles should not exceed 5000 words, or approximately 20 double-spaced typewritten pages, including tables, references, and an abstract of 200 words or fewer. All manuscripts submitted as Articles are reviewed by at least two referees. Research Reports, which are usually reviewed by at least one outside referee, should not exceed 1500 words or include more than two figures. Research Reports address technical developments, describe well-documented but preliminary research results, or present findings for which the Article format is not appropriate. Book or monograph Reviews of 500 words or less are also considered. Other categories of papers are occasionally published. All papers are published only in English. Abstracts of the Articles or Reports may be printed in other languages if supplied by the author(s) with English translations.
