摘要
文章应用三种不同下垫面近地面层风速和温度梯度资料，代入风速和温度廓线公式，迭代求得感热通量及热量交换系数．确定Ｋｈ／Ｋｗ与稳定度参数ξ的关系式．分别利用空气动力学方法和波文比能量平衡法计算潜热通量，并进行了比较．
Based on the wind velocity and temperature gradient data of surface layers from three kinds of underlying surfaces,the sensible heat flux and the coefficient of heat exchange are obtained through iteration using the profile formula of wind velocity and temperature.Therefore the relationship formula between Kh/Kw and stability ξis established.And then the latent heat flux is calculated using the aerodynamics method and Bowen ratio-energy balance method,respectively.The calculated results of these two methods are compared with each other.
