13C at Natural Abundance Levels in the Broad-leaved Deciduous Forest in the Warm-temperate Region of China: Their δ13C Values and Ecological Significance
Abstract:We analyzed the stable carbon ratio of some tree species of a broad\|leafed deciduous forest in the warm\|temperate region of China. The results showed that there were significant differences in the foliar δ 13 C values among tree species. The δ 13 C values of most species ranged from -24 751‰±0 854‰ to -28 113‰±1 519‰. We categorized these tree species into three groups based on their foliage δ 13 C values. The foliage δ 13 C values of the Group Ⅰ plants were greater than -25 5‰, while...
