| 摘 要： | 本文结合江苏实际情况，改进了彭曼公式中的系数，加入作物需水系数和土壤供水系数，建立农田蒸散量的计算模式，计算出淮北地区主要作物全生育期需水量及时分布规律。同时，提出了20cm小型蒸发器产测蒸发量与标准蒸散量的统计模式，以此作为计算农田实际蒸散量的补充方法。

| Abstract: | his paper computes water requirements for major crops covering the entiregrowing period and the spatial-temporal distribution laws in Huaibei area byusing an evapotranspiration computation model which is devdoped based on the improvement of coefficients in penman's formula and incorporation of crop water requirement and soil water supply coefficients as well as combination with actualconditions in Jiangsu province. Meanwhile the measuring of evaporation with amini evaporation gauge of 20cm in diameter and the statistical model for standardevapotranspiration are introduced as a supplementary method for computation ofactual field evapotranspiration. |
