| 英文摘要 | CO2 concentrations at different heights in a broadleaved/Korean forest (with a mean height of 26 m) were measured with infrared gas analyzer IRGA (model 2250D, LI-COR inc. and LI-COR, 820) from Aug. to Oct. of 1999, Apr. to Jul. of 2000,and from Aug. 2002 to Sept. 2003. Based on the collected dada, the diurnal and seasonal dynamics of profiles and storage of carbon dioxide in the forest were analyzed. The diurnal CO2 profites showed that the verticat distribution of CO2 concentration were different for daytime and nighttime, and the CO2 concentration was highest close to forest floor, no matter at daytime and nighttime. The seasonal profiles of CO2 showed that stratification in the canopy was evident during growth season. CO2 concentrations at different heights (60 m to 2.5 m) had a little change in March, with a difference of 10μmol·mol^-1, but had a significant change in July, with a difference of 60μmol·mol^-1, In July, there also existed a greater gradient of CO2 concentrations at canopy (22, 26 and 32 m), with a difference of 8μmol·mol^-1. The calculated total storage ( Δ C/Δ t) of CO2 in the air column with height of 40 m beneath eddy covariance instrument was negative, and made a little contribution to NEE. |
