摘要
依据ＳＰＡＣ原理，通过田间水热耦合运移的数值模拟，对夏玉米田蒸散进行了研究，提出了整体冠层阻力的经验表达式，并对蒸散模式中的其它两个阻力参数进行了详细的分析和讨论。验证结果表明，本文提出的模型和模拟计算方法是有效而实用的。
Abstract Based on the principles of SPACsystenm，in this paper, the methods of evapotranspiration estima-tion in summer corn field are established by the numerical modelling of water and heat coupling move-ment in field，the emperical equation of reSistance in canopy is presented ， and the other two resistanceparameters in models are analysed. the results of test and verification show that the models and calcu-lated methods presented in this paper are practicable and efficient.Key wards，Evapotraspiration Water and heat cou pl ing movement Canopy resistance
