| 英文摘要 | The interest in the development and improvement of dynamic global vegetation models (dgvms), which have the potential to simulate fluxes of carbon, water and nitrogen, along with changes in the vegetation dynamics, within an integrated system, has been increasing. in this paper, some numerical schemes and a higher resolution soil texture dataset were employed to improve the sheffield dynamic global vegetation model (sdgvm). using eddy covariance-based measurements, we then tested the standard version of the sdgvm and the modified version of the sdgvm. detailed observations of daily carbon and water fluxes made at the upland oak forest on the walker branch watershed in tennessee, usa offered a unique opportunity for these comparisons. the results revealed that the modified version of the sdgvm did a reasonable job of simulating the carbon and water flux and the variation of soil water content (swc). however, at the end of the growing season, it failed to simulate the effect of the limitations on the soil respiration dynamics and as a result underestimated this respiration. it was also noted that the modified version overestimated the increase in the swc following summer rainfall, which was attributed to an inadequate representation of the ground water and thermal cycle. |
