초록

The purpose of this study is to monitor the flux of CO2 and BVOCs (biogenic volatile organic compounds)between the atmosphere and forest. The main research activities are conducted at Taehwa Research Forest (TRF),managed by the College of Agriculture and Life Sciences at Seoul National University. The TRF site is located 60km north-east from the center of Seoul Metropolitan Area. The TRF flux tower is in the middle of a Korean Pine (Pinus Koraiensis) plantation (400m×400 m), surrounded by a mixed forest.
Eddy covariance method was used for CO2 flux above the forest and REA (Relaxed eddy accumulation) method applying eddy covariance was used for BVOCs flux.
BVOCs flux that was measured in spring (from May 16 to 18) had distribution of 84 to 2917 μg/m2∙h. Especially,it showed that d-limonene being strong reactivity composed the largest fraction of monoterpene.
Ambient CO2 concentration measured in Mt. Taehwa was 399 ppm and observed CO2 fluxes between the atmosphere and forest suggested that during the day, CO2 is absorbed by plants through photosynthesis and released during the night.
