摘要:

对采自中国东部亚热带地区的浙江天目山、江西庐山及江苏南京紫金山地区的金钱松(Pseudolarix kaempferi)、冷杉(Abiesfab ricraib)及马尾松(Pinus massoniana)树轮,分别测定它们不同方位10 a、20 a及3 a树轮δ13C序列,探讨不同树种树轮δ13C存在的方位差异与年际变化普遍性。结果表明,在中国东部亚热带地区,树轮δ13C方位差异与年际变化存在普遍性。表现为3个地区、3个树种之间存在差异;同一地区不同树种及相同树种不同个体之间也存在差异;同一个体在相同年份存在方位差异及相同方位存在年际变化等;表明研究树轮δ13C的方位差异与研究其年际变化同样具有重要价值与意义。

关键词: 树轮δ13C, 方位变化, 年际变化, 普遍性

Abstract:

After measuring respectively the δ13C annual series in different azimuths based on cross-dated tree ring age for ten years, twenty years and three years of Pseudolarix kaempferi (PK)tree discs collected from Tiamu Mountain, Zhejiang Province, Abiesfab ricraib(AF) tree discs collected from Lusan Mountain, Jiangxi Province, and Pinus massoniana(PM) tree discs collected from Purple Mountain, Jiangsu Province, the universality of the tree ring δ13C azimuth change and inter-annual variability in different species were discussed. The research result shows that the azimuth change and inter-annual variability of the δ13C in tree ring exists universally. The δ13C is different in different areas and in different species, there are differences in different species in the same region and in different individuals in the same species, the δ13C of the same individual has azimuth change in the same year and inter-annual variability in the same azimuth, etc.

Key words: tree ring δ13C, azimuth change, inter-annual variability, universality
