| 摘 要： | 在运用Ｐｅｎｍａｎ－Ｍｏｎｔｅｉｔｈ公式计算农田蒸散时，综合考虑了大气稳定度的影响。通过引入适应指数公式，检验稳定度修正前后对农田蒸散计算的精度影响。结果表明，修正后的公式计算公式精度明显下降，平均绝对误差增大一倍多，由此证明在计算农田蒸散时不考虑大气稳定度的订正是完全可靠的。此结论与文献［２］的研究结果一致。

| Abstract: | The effect of atmospheric stability has been considered in calculating ET fromfields bv Penman-Monteith method.By introducing the equation of the lndex of Agreement,the effect on accuracies of ET calculations with and withotit adjustment of the stability havebeen examined.Results show that the. accuracy of the calculation by the revised equation issharply reduced with the mean absolute error increased by as > 100%.Therefore,it is feasi-ble to neglect the correction of atmospheric stability in calculating ET. The result is in agree-ment with the reference(2)conclusion. |
