13C/12C ratio in tree ring of subtropical monsoon evergreen broad-leaved forest and CO2concentration in atmosphere

Abstract

Abstract: The ¹³C/¹²Cratio (δ¹³C) in tree ring of subtropical monsoon evergreen broad-leaved forest is determined in this paper. The average δ¹³Cis-28.53±0.84（n=5） for Aporosa yunnanensis from 1962 to 1983, -28.46±0.53（n=6） for Machilus chinensis from 1951 to 1984, -29.19±0.80 （n=6） for Cryptocarya concinna from 1951 to 1984 and -28.42±0.41（n=4） for Schirna superba from 1975 to 1984. Deviation of δ¹³Cfrom mean increases year by year, and calculated CO₂ concentration in atmosphere increases by 1.21 μl/Lyearly.

Key words: Subtropical monsoon evergreen forest, σ¹³C in tree ring, Atmospheric CO₂ concentration
