基于月值气象数据和Penman-Monteith公式的流域蒸散发量计算
|
摘要
Penman-Monteith方程是联合国粮农组织(FAO)推荐使用的计算蒸散发量的公式,应用广泛,而利用月值气象数据计算蒸发量与日值数据计算有很大不同。以汾河流域为例,基于月值气象数据和Penman-Monteith公式计算汾河流域的蒸发量。结果表明,基于Penman-Monteith公式计算的汾河流域蒸发量是比较准确的,可为以后蒸发量计算提供参考。
The Penman-Monteith equation is a formula used by the Food and Agriculture Organization of the United Nations(FAO) to calculate evapotranspiration. It is widely used, and using monthly meteorological data to calculate evapotranspiration is very different from that of daily data. Taking the Fenhe River Basin as an example, the evaporation of the Fenhe River Basin is calculated based on the monthly meteorological data and the Penman-Monteith formula. The results show that the evaporation in the Fenhe River basin based on the Penman-Monteith formula is relatively accurate and can provide a reference for the calculation of evaporation in the future.
