AbstractBased on surface energy flux data measured by eddy covariance methods from China Flux in alpine swamp meadow of the Qinghai Tibetan Plateau in 2005, the daily and seasonal dynamic of surface energy fluxes and their partitioning, as well as abiotic factors effects were analyzed. The results suggested that LE (Latent heat flux) was the largest consumer of the incoming energy. Rn (Net radiation flux) and LE showed clear seasonal variations in sharp hump and up to their maximums in August and July, respectively. H (Sensible heat flux) increased to its peak in August whereafter declined slowly. Precipitation could reduce the components of surface energy. As to Rn and LE, their correlations with abiotic factors were evident while it was not significant in H. Average EBR (Energy balance ratio) was 50.7 %, which was much larger in growing season than non-growing season.; Based on surface energy flux data measured by eddy covariance methods from China Flux in alpine swamp meadow of the Qinghai Tibetan Plateau in 2005, the daily and seasonal dynamic of surface energy fluxes and their partitioning, as well as abiotic factors effects were analyzed.
