| 摘 要： | 该文建立了在部分植被条件下估算农田蒸散的双层模型，利用此模型和ＮＯＡＡ－ＡＶＨＲＲ数据对黄淮海平原春季旱情进行了评估，并做出了干旱及蒸散分布图。对双层模型和单层模型的估算结果进行了比较，结果表明在部分植被条件下双层模型估算的精度要高。

| Abstract: | In this paper a tow-layer model for evaportranspiration is estiblished in partial vegetation canopy. The vegetation canopy
has two layers, the first one extends. from a refrence height in the atmosphere to the virtual sink for momentum and the second one from the virtual sink to the soil surface. NOAA-AVHRR data and the two-layer model are applied to estimate evaportranspiration and drought of wheat grown in Huang Huai Hai plain. |
