Soil–atmosphere exchange of N2O, CO2 and CH4 along a slope of an evergreen broad-leaved forest in southern China

Abstract: At most sites the magnitude of soil-atmosphere exchange of nitrous dioxide (N 2 O), carbon dioxide (CO 2 ) and methane (CH 4 ) was estimated based on a few chambers located in a limited area. Topography has been demonstrated to influence the production and consumption of these gases in temperate ecosystems, but this aspect has often been ignored in tropical areas. In this study, we investigated spatial variability of the net fluxes of these gases along a 100 m long slope of a evergreen broadleaved forest in so… Show more

“…The temporal variations of CH 4 uptake by forests in China were discussed in many studies (Sun, 2000;Dong et al, 2003;Du et al, 2004;Mo et al, 2006;Tang et al, 2006;Fang et al, 2009;Yang et al, 2010;Liu et al, 2010aLiu et al, , 2010bHu et al, 2011;Li, 2011;Zhang et al, 2011a;Yang, 2012;Liu et al, 2012b). Several studies reported great diurnal variations of CH 4 uptake rates with no significant relations between CH 4 uptake and soil moisture or temperature Mo et al, 2005;Yang et al, 2010;Hu et al, 2011).…”

“…Shimada et al (1998) on the lower slope and 9.9 MgC ha À1 year À1 on the upper slope in a Japanese coniferous plantation. However, no correlation (Fang et al 2009), and the opposite trend, namely lower soil respiration rates on the lower slope and at the valley bottom than the upper slope (Chambers et al 2004;Tsutsumi et al 1985;Epron et al 2006;Mitani et al 2006;Kosugi et al 2007) have been reported in several forest ecosystems. Although many reports have suggested that soil respiration varies with slope position, no general principle concerning the relationship between slope position and soil respiration has yet been established.…”

“…However, topography could influence other environmental factors, such as temperature, water, and nutrients, which control the soil carbon cycling process (Hishi et al, 2004;Fang et al, 2009). Along hill slopes, the soil carbon would have different distribution trends under different vegetation types.…”
