Climate change can significantly affect carbon cycling of forest ecosystems. The diurnal and seasonal dynamics of soil respiration (R s) in Cinnamomum camphora and Liquidambar formosana forests were investigated by using infrared gas exchange analyzer of Li-Cor 6400-09 each month in 2006. Soil temperature and moisture were also measured. Diurnal variations in R s varied with daily soil temperature in the two forests. Across the growing season, soil respiration peaked on July 28 due to higher soil temperature and moisture conditions. Seasonal ...

土壤呼吸是构成森林生态系统碳平衡的重要组成部分,在全球碳平衡中扮演着十分重要的角色.樟树(Cinnamomum camphora)是中国业热带地区地带性植被常绿阔叶林的优势树种,枫香(Liquidambar formosana)是次生演替早期的优势树种,研究以这两种树种为主要组成的森林土壤呼吸有助于了解亚热带地区(森林碳源汇时空分布格局及碳循环过程驱动因子.
