摘　　要：讨论了绿洲边缘地带的温湿风廓线及日变化特征，用Businger模式计算了显热通量，并将结果与波文比法、涡度相关法作了比较．There are many methods for calculating pensible and latent nuxes between ground surface and atmosphere, the flux-profile relationship for example, is one of those. Based on the data observed in wheat field by the border of oases in Zhangye, Gansu Province during a period of May-June, 1992, the characteristics of profile of wind speed, temperature and humidity are analyzed. The result shows that the isotherm layer appears at 7 and 16-17 o'clock approximately. At the same time, the sensible and latent fluxes were calculated by flux-profile relationship (Businger model ), and compared with the results estimated by other two methods (Bowen Ratio method and Eddy Correlation method). The results show that the latent flux calculated by Businger model is close to that by other two methods when wind speed is not so large and wind direction is not from gobi or dcsert.
