摘要: 传统的树轮气候学重建研究是基于现代仪器观测资料和树轮序列的统计相关实现的,缺乏机制方面的研究。可靠地重建历史时期的气候变化,需要理解树木径向生长的气候响应机理。目前,国际上的树木径向生长机制研究主要有两种途径,监测与模拟,其中监测研究包括应用树木径向生长测量仪(Dendrometer),微树芯法(Micro-coring)和针刺创伤法(Pinning)3种。从两类大的研究途径出发,综述了国内外的研究进展情况,并对未来发展趋势提出展望。

Abstract: The traditional dendroclimatology is based on the statistical correlation between observations of modern equipment and chronologies from tree rings. In order to reconstruct paleoclimate reliably,the response mechanism of radial growth to climatic factors should be concerned well. Currently,there are two main approaches in the research area: monitor and model. The monitor approach contains dendrometer, micro-coring and pinning. In this paper, the four most popular methods are discussed in detail. The research progress is summarized and some prospects for future development are given.

Key words: model, dendrometer, micro-coring, pinning
