| Research Abstract |
The enlargement of the typhoon is expected along with global warming, and the influence of the typhoon disturbance cannot be disregarded in evaluating the forest CO_2 budget. Then, the forest function for CO_2 absorption after typhoon disturbance was researched. Before the wind damage, the absorbed amount of CO_2 by photosynthesis in the forest canopy had exceeded the CO_2 emission by respiration in soil and coarse wood debris. After the wind damage, both photosynthesis and respiration reversing, CO_2 was emitted from forest ecosystems into atmosphere.
