수분 및 온도의 변화에 따른 산림 토양의 잠재 토양 호흡

Soil respiration in forests represents about 70% of total ecosystem respiration. Soil respiration rate was affected soil temperature and soil water content. Our objective of this study is to understand how temperature and moisture condition affects on the soil respiration in different mature stage and forest type, measured soil respiration (SR) on various temperature and moisture conditions. Soils were collected deciduous and coniferous in different development stage at in Korea. Soil respiration was calculated by closed method in growth chamber. In general, soil respiration were strongly affected to increasing soil temperature compared with soil moisture content. Over all, deciduous forest soil showed higher SR than the coniferous forest soil. Also, mature forest soil represented higher SR than the immature forest soil. This study suggests that global warming can alter soil in mature deciduous forest from sink to source than in immature coniferous forest.
