Model of Soil Water Evapotranspiration in the Condition of Water Stress

doi:10.3321/j.issn:1000-7091.1993.04.006

Abstract

Abstract: A model of soil water evapotranspiration in farmland under the condition of water stress has been established. In the condition of water stress, the relationship between actual evapotranspiration capacity (ET) and potential evapotranspiration capacity (ETm) is ET = Kw·ETm There is a linear correlation between Kw and the content of availabel water in root region. The accuracy of modelling can be improved by introducing the effect of root distribution into the model.

Key words: Model, Soil water evapotranspiration, Water stress
