抄録

The physiological relationships between photosynthesis and CO₂ concentration are summarized. Net primary production is estimated by a mathematical model of plant Community based on the interaction of photosynthesis and environmental factors such as light and CO₂ conditions. The model predicts an increase of 110 mg CO₂/dm²/day in net primary productivity due to CO₂ enrichment from 400 to 600 ppm. The potential increase of global net primary production of vegetation is evaluated to be 0.27×10¹⁵ g C/year, a value being less than 6% of the present CO₂ production rate derived from the burning of fossil fuels. The actual increase which is taken water shortage and other unfavorable environmental conditions into consideration would be of minor importance in the present context.
