“…In Japanese forests, researchers have used the alkali absorption method (AA), open-flow dynamic method (OF), dynamic closed methods (DC), open-top chamber method (OTC), automatic opening and closing chamber method (AOCC), and the soil CO 2 concentration gradient method (CO 2 gradient). Of the 26 studies listed in Table 1, 19 used AA, although more recent studies used OF (Ohashi et al 1999(Ohashi et al , 2000Takahashi et al 2004;Lee et al 2005;Mo et al 2005a), DC (Yim et al 2002;Mitani et al 2003), OTC and AOCC (Liang et al 2004), and CO 2 gradient (Liang et al 2004;Takahashi et al 2004). Yim et al (2002) and Liang et al (2004) compared methods at the same site (Tomakomai Flux Site in Hokkaido, Japan).…”

Within terrestrial ecosystems, soil respiration is one of the largest carbon flux components. We discuss the factors controlling soil respiration, while focusing on research conducted at the Takayama Experimental Site. Soil respiration was affected by soil temperature, soil moisture, rainfall events, typhoons, and root respiration. We consider the temporal and spatial variability of soil respiration at the Takayama Experimental Site and review the variability of annual soil respiration in Japanese forests. In the 26 compiled studies, the values of annual soil respiration ranged from 203 to 1,290 g C m À2 year À1 , with a mean value of 669 g C m À2 year À1 (SD=264, CV=40). We note the need for more studies and data synthesis for the accurate prediction of soil respiration and soil carbon dynamics in Japanese forests. Finally, several methods for measuring soil respiration rates are compared and the implications of soil respiration rates for global climate change are discussed.
