Typhoon disturbance effects on carbon dioxide budget and fluxes in broad-leaved forest.

随着全球气候变暖，台风的影响将沿着扩大，在估算森林CO2收支时，台风扰动的影响不可忽视。在此基础上，研究了台风干扰后森林对CO_2的吸收作用。在风害发生前，林冠光合作用吸收的CO_2量已超过土壤和粗木残体呼吸释放的CO_2量。风害发生后，森林生态系统的光合作用和呼吸作用发生逆转，CO_2被释放到大气中。

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.
