关于棉田感热通量和潜热通量的几种计算方法

THE ANALYSIS ON METHODS OF THE CALCULATION OF SENSIBLE AND LATENT HEAT FLUX

根据棉田的实测资料，选用四种常用的计算感热通量和潜热通量的方法进行分析，发现空气动力学方法Ⅰ和伯温比－能量平衡法的计算结果较一致，梯度扩散法略小，而布德科方法计算的潜热通量偏高、感热通量过低。因此得出结论：在计算棉花等作物的冠层通量时，选用空气动力学方法Ⅰ最合适，其次是梯度扩散法。

Based on the data observed in the cotton field, the analysis of four several methods for calculation of sensible and latent heat flux has made. There are consistent results between Method Aerodynamic I and Method Bowen-Ratio,some lower values for Method Gradient-diffusion, and unstable results for Method M. И. budek. So Method Aerodynamic I is the best one to calculate fluxes inside cotton canopy.
