Abstract: Stomatal responses of plant to elevated CO2 are as follwing:from the plant to global scale,decreased stomatal conductance and density at leaf scale;reduced transpiration per unit leaf area and increased water use efficiency at plant scale;decreased evapotranspiration and elevated run off and soil moisture at ecosystem scale;and amplifying the greenhouse gas effect in increasing temperature,but inhibiting the increasing precipitation at global scale.It plays an important role in global changes by effecting the water cycle.But the current result of research at small scales cannot been scaled up directly to large ones.
