摘要
随着稳定同位素分析技术的进步和植物生理学研究的发展,稳定同位素在树轮气候研究中扮演着日益重要的角色。本文总结了用于气候分析的树木年轮稳定同位素资料获取与质量控制方法。包括对分析树轮样品的要求、树轮纤维素提取实验流程、树轮同位素的质谱分析方法和稳定碳同位素数据的处理方法等。为树轮稳定同位素实验分析提供参考,便于获得可靠的树轮同位素数据,且能够进行不同实验室之间数据结果的对比,为建立树木年轮同位素网络奠定基础。
With the development of plant physiology and mass spectrometry analysis technique, stable isotope played a more and more important role in dendroclimatology. This paper summarized the method of tree ring stable isotope data acquisition and its quality control for dendroclimatological research. It included the requirement for the tree ring sample, extracting procedure of tree ring cellulose, the mass spectrograph analysis method for tree ring stable isotope and the data treatment method. It would provide the references for tree ring stable isotope research, enhance the data comparability between laboratories, and establish the foundation of tree ring stable isotope network.
