| 中文摘要 | co(2) efflux was estimated using different regression methods in static chamber observation from an alpine meadow on the qinghai-tibetan plateau. the co(2) efflux showed a seasonal pattern, with the maximun flux occurring in the middle of july. the temperature sensitivity of co(2) efflux (q (10)) was 3.9, which was at the high end of the range of global values. co(2) emissions calculated by linear and nonlinear regression were significantly different (p < 0.05). compared with the linear regression, co(2) emissions calculated by exponential regression and quadratic regression were 12.7% and 11.2% larger, respectively. however, there were no significant differences in temperature sensitivity values estimated by the three methods. in the entire growing season, the co(2) efflux estimated by linear regression may be underestimated by up to 25% compared to the real co(2) efflux. consequently, great caution should be taken when using published flux data obtained by linear regression of static chamber observations to estimate the regional co(2) flux in alpine meadows on the qinghai-tibetan plateau. |
