| 摘 要： | 本文介绍了用一日一次观测资料计算全日农田蒸散总量的模式,该模式由二部分公式组成,一是计算瞬时农田蒸散量的空气动力学阻抗——能量平衡公式,另一是根据遥感作物表面温度、农田净辐射、土壤热通量等参数的一次观测资料,计算全天蒸散总量。

| Abstract: | A simple model estimated daily total value of ET from one time of day measurement has been introduced in this paper.The model is made by two formulas, first is the aerodynamic resistance-energy balance model for estimating instantaneous values of E, second is a formula to assessment the daily total value of ET from one time of day measurements of net radiation, soil heat flux, air temperature, wind speed, crop canopy temperature, the data of latitute anl solar declination. |
