“…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).…”
