农田蒸散测算的微气象学方法

Mircro Meterlolgical Methods for Measuring and Estimating Evapotranspiration in Farmland

介绍了国内外广泛采用的测算农田蒸散的微气象学方法，如涡度相关法、空气动力学法、空气动力学相合、鲍恩比—能量衡量法、Ｈ扣除法等。探讨了这些方法误差来源、特点及使用中应该注意的问题。

This paper introduces the micro meterological methods vorticity cor-relation method ,aerodynamic method,aerodynamic combination method,Boen Ratio-energy balance method and H exclusive method widely-adopted to measure and estimateevapotranspiration in farmland both at home and abroad in details. Also ,it deals witherror sources and characteristics and some problems concernign their practical uses ofthese methods.
