文摘The carbon isotope ratios(δ^(13)C) of modern land plants have been widely studied,and they provide valuable information about modern and past atmospheric,ecological and climatic changes [1].According to their different photosynthetic pathways,land plants are mostly C_(3) and C_(4) plants.The δ^(13)C values of C_(3) plants are mainly within the range of-20‰ to-34‰.
