| Research Abstract |
Estimation of forest ecosystem respiration was conducted using eddy covariance, chamber and modeling approaches at deciduous-ever green mixed forest in northern Kyoto in Japan. Both autotrophic and heterotrophic respiration, respiration intensity highly depended on medium size (e.g.root diameter). Increase of plant growth respiration in spring and decrease of heterotrophic respiration by lack of decomposable material highly affected seasonal change of forest ecosystem respiration.
