英语翻译Some have argued that the greater production of plant litter under elevated CO2 (eCO2),especially woody detritus,could act as a governor on the CO2 enhancement of forest NPP by negatively impacting the terrestrial N cycle .Under such scenarios,the microbial decay of plant detritus slows,the accumulation of N from plant detritus into longlived soil organic matter increases and the supply of growth-limiting soil N to plants declines.This series of events could dampen or eliminate the extent to which eCO2 enhances NPP,having global implications for C storage on land as well as the future concentration of CO2 in the atmosphere.
