Soil respiration and some environmental factors which affect soil respiration were studied in an oak forest, Kongju, Korea. Soil respiration was measured at midday of the 15th and 30th day at every month in control(Con), artificial forest gap (Gap) and litter removed area (Lr) with portable CO©ü Analyzer equipped soil respiration chamber. In July, maximum soil respiration in Con, Cap and Lr was 15.6, 11.2 and 7.7 CO©ü¥ìmol¡¤m/sup -2/¡¤s/sup -1/, respectively. Respiration in Gap and Lr decreased by 28.6% and 50.6%, respectively, compared with that in Con. Annual amount of soil CO©ü evolution from Con, Gap and Lr was 6.86, 5.84, 3.81 kg¡¤m/sup -2/¡¤yr/sup -1/, respectively. Annual amount of CO©ü evolution in Gap and Lr decreased by 14.8% and 44.5%, respectively, compared with that in Con. Soil respiration rates exponentially increased with temperature. Temperature of soil surface and at 5 cm depth was strongly related to soil respiration rates in Con (r©ü£½0.87, 0.93), Gap (r©ü=0.81, 0.88) and Lr (r/sub 2/=0.89).
