Description:
Underestimated effects of low temperature during early growing season on carbon sequestration of a subtropical coniferous plantation Biogeosciences, 8, 1667-1678, 2011 Author(s): W.-J. Zhang, H.-M. Wang, F.-T. Yang, Y.-H. Yi, X.-F. Wen, X.-M. Sun, G.-R. Yu, Y.-D. Wang, and J.-C. Ning The impact of air temperature in early growing season on the carbon sequestration of a subtropical coniferous plantation was discussed through analyzing the eddy flux observations at Qianyanzhou (QYZ) site in southern China from 2003 to 2008. This site experienced two cold early growing seasons (with temperature anomalies of 2–5 °C) in 2005 and 2008, and a severe summer drought in 2003. Results indicated that the low air temperature from January to March was the major factor controlling the inter-annual variations in net carbon uptake at this site, rather than the previously thought summer drought. The accumulative air temperature from January to February showed high correlation ( R 2 =0.970, p
