中文摘要：

从蒸散量和水面蒸发量之比与主要根系层平均含水率的关系出发，利用在中国科学院阿克苏水平衡试验站芦苇试验小区监测的土壤水分和蒸散资料，建立了干旱区芦苇蒸散量的计算模式，并利用芦苇实际蒸散量的测量值，对模式进行了验证。结果表明，模式计算精度较高，可以作为计算干旱区芦苇蒸散量的一种计算方法而使用。

英文摘要：

Based on the relation between the ratio of evapotranspiration and evaporation from water surfaces ETa/ EO and the average soil moisture content of root zone, and by the soil moisture and evapotranspiration data of reed experimental plot in Aksu water balance experimental station of Chinese academy of sciences, a calculation model of reed evapotranspiration of arid zone was established and verified with the evapotranspiration directly measured in the experimental plot. The result revealed that the model had high precision with its relative error ranging within 4% and could be used to calculate the evapotranspiration of reed of arid zone.
