| 摘 要： | 根据SPAC模型对不同灌水处理下冬小麦返青至成熟期田间水热传输及转化规律的数值模拟结果，拟合了根据地表以下1m土层贮水量和参考作物腾发量进行农田蒸散发估算的经验公式。利用经验公式和SPAC模型对不同灌水处理和不同潜水埋深下冬小麦返青至成熟期的蒸散发进行了计算，结果吻合良好。

| Abstract: | Based on the simulation results of water and heat transfer in winter wheat field with soil-plant-atmosphere continuum(SPAC) model, the empirical formula for estimating crop evapotranspiration from the reference evapotranspiration and soil water storage between soil surface to 1m below is established. The empirical formula and SPAC model simulation are in good agreement under different irrigation treatments and different groundwater depths in winter wheatgrowing period from greening to mature. |
