| Abstract: | The soil CO2 evolution rate was measured in a virgin Korean pine forest. The results in June showed that the lowest value of evolution
rate was 220 mg/(m2·h) and appeared at 6:00 a.m. The highest value was 460 mg/(m2·h) at 18:00. The rates of CO2 evolution were related with soil temperature. On the basis of the constructed regression equation and the monthly average
values of temperature, the magnitude of CO2 evolution from Korean pine forest soil was 10.4 t/hm2 during a growing season.
This project was funded by the Opened Research Station of Changbai Mountain Forest Ecosystem, Chinese Academy of Sciences.
