| 中文摘要: |
| 本文在Penman-Monteith公式的基础上，推导出能解析计算冠层蒸腾和土壤蒸发的双源模型，使之能广泛用于农田蒸腾和蒸发的计算.采用玉米田波文比椖芰科胶?BREB)观测资料对模型进行检验，模拟的蒸散量与BREB的结果相当一致.模型主要参数对蒸散的敏感性分析表明，这些参数变化±20%时，蒸散的响应小于±7%. |
| 英文摘要: |
| An improved dual-source model is proposed by which the canopy transpiration and underneath soil evaporation can be estimated analytically. The model is testified by surface energy balance data collected in summer maize field. The output evapotranspiration is in good agreement with that calculated by Bowen ratio-energy balance method. Sensitivities of some main parameters for evapotranspiration show that the variation of enapotranspiration is less than 7%when parameters vary in the range of±20%. |
