우리나라 소나무림의 토양호흡 특성: 점봉산, 남산, 지리산 사례 연구 (2009~2010)

This study measured soil respiration in pine forests dominated by Pinus densiflora in Mt. Jeombong, Mt. Namsan, Mt. Jirisan in Republic of Korea from 2009 to 2010. The seasonal variations, along with temperature and soil moisture content, were measured to understand the characteristics at each site. Soil respiration was highest in summer and autumn, closely influenced by the increase in soil temperature. Throughout the measurement period, soil respiration ranged from 205.6 to 312.2 mg CO 2 m -2 h -1 , with Mt. Namsan showing the highest values and Mt. Jirisan the lowest. A strong correlation was observed between soil respiration and soil temperature, with Q 10 values ranging from 2.5 to 3.0. Precipitation significantly affected soil moisture content, and although it appeared to influence soil respiration, no significant correlation was found.
