Abstract: Using infra-red gas analyzer and tube-type air sampling unit, the SO2 concentrations at different heights are measured in natural and secondary korean pine-broad leaved mixed forests on Changbai Mountain.CO2 in forest stands changes diurnally:in canopy, it decreases during day time and increases at night. CO2 in forest stands are supplied both from forest floor and atmosphere above canopy. Higher concentration of CO2 near ground surface provides better CO2 environment for regenerated seedlings than in upper layers.
