摘要
为了找到适合鄂尔多斯高原区参考作物蒸散量(ET_0)的计算方法,根据当地气象站监测的1961年1月至2010年12月的逐日气象数据,以FAO56Penman-Monteith法为标准,分别对FAO-79Penman法、Irmark-Allen法、Priestley-Taylor法和Hargreaves-Samani法进行对比分析,应用线性回归和方差分析对这4种方法的适应性进行评价。结果表明:在鄂尔多斯高原区FAO-79Penman法和Irmark-Allen法与FAO56Penman-Monteith法的计算结果更接近,因此在鄂尔多斯高原区可以用FAO-79Penman方法计算ET_0值;在缺少湿度和风速资料的地区,可以用Irmark-Allen方法代替FAO56Penman-Monteith法计算ET_0值。
In order to find the suitable calculation methods for reference crop evapotranspiration(ET_0) of the Ordos Plateau area and based on the daily meteorological data from January 1961 to December 2010 monitored by local weather stations,taking the FAO56 Penman-Monteith method as the standard to compare with the FAO-79 Penman method,Irmark-Allen method,Priestley-Taylor method,and Hargreaves-Samani method,the ET_0 values were calculated respectively,and the adaptabilities of these four methods were evaluated by linear regression and variance analysis.The results showed that the calculation results by Irmark-Allen method and FAO-79 Penman method were closer to those of the FAO56 Penman-Monteith method in the Ordos Plateau area.Therefore,the ET_0 value can be calculated using the FAO-79 Penman method in the Ordos Plateau area.If there are no humidity or wind speed data,the Irmark-Allen method can replace the FAO56 Penman-Monteith method to calculate the ET_0 value.
