摘要
采用同位素比率质谱仪分别测定了树木不同部位的δ^(13)C、δ^(18)O和δ^(2)H值。结果表明:δ^(13)C值在研究树种植株不同部位的变化相对最小,其次是δ^(18)O值,δ^(2)H值最大。对于橡胶木、铁刀木和羊蹄甲3个树种,C和O元素是实现其木材产地稳定同位素溯源较理想的元素。
Isotope ratio mass spectrometer was adopted to determineδ^(13)C,δ^(18)O andδ^(2)H values in different parts of the tree.The findings indicated that theδ^(13)C values in wood different part were the smallest,followed by theδ^(18)O value and theδ^(2)H value.For the 3 tree species of Hevea brasiliensis,Cassia siamea and Bauhinia blakeana,C and O are ideal elements for stable isotopic traceability of wood origin.
