摘要
Terrestrial plants uptake carbon dioxide from the atmosphere by photosynthetic carbon dioxide assimilation.This flux,known as gross primary productivity,is the largest carbon dioxide flux between the atmosphere and the land surface,and accounts for approximately 120 billion tonnes of carbon per year[1].Global terrestrial gross primary productivity varies with environmental conditions,and,according to an analysis of atmospheric carbonyl sulfide records,increased by 31%over the twentieth century[2].
