| 摘 要： | 从植被冠层和陆地表面出发,发展一种基于遥感数据和地表气象参数观测数据的陆面蒸发散量计算的两层阻抗模型。该方法主要遵循能量平衡原理,并充分考虑到冠层小气候对土壤和植被的不同影响,从而分别针对土壤和植被进行模型的参数化。该方法经过大尺度非均匀陆面条件验证,获得了较高的精度。

| Abstract: | A new method is developed here to model daily evapotranspiration over large areas by combining remote sensing data and ground-based meteorological variables.However,many differences of surface parameters between transpiration and evaporation are more complex because the transpiration from vegetation is affected by the physiological characteristics of the vegetation.Thus,this model describes the parameters separately.The model is validated at large scale with homogeneous surface conditions,good agreement is obtained between model estimates and the measurements at ground stations. |
