| 英文摘要 | Continuous eddy covariance measurements of CO(2), water vapor, and heat fluxes were obtained from a maize field within an oasis in northwest China from 1 May 2008 to 30 April 2009. The experimental setup used was shown to provide reliable flux estimates on the basis of cross-checks made using various quality tests of the flux data. Results show that the highest half-hourly CO2 fluxes (Fe) were -55.7 and 6.9 mu mol m(-2) s(-1) during the growing and nongrowing seasons, respectively. The daily net ecosystem exchange of carbon (NEE) ranged from -14.7 to 2.2 g C m(-2) day(-1) during the growing season; however, the daily NEE fell to between 0.2 and 2.1 g C m(-2) day(-1) during the nongrowing season. The annual NEE calculated by integrating flux measurements and filling in missing and spurious data was about -487.9 g C m(-2). The total NEE during the growing season (-692.9 g C m(-2)) and the annual NEE were in the middle of the range, when compared with results obtained for maize fields in different studies and regions, whereas the differences between the off-season NEE from this study (205.0 g C m(-2)) and those defined in previous studies were very small. In addition, the seasonal variations in energy balance and evapotranspiration over the maize field were also addressed. |
