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(ET0)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 FAO56Penman-Monteith method as the standard to compare with the FAO-79Penman method,Irmark-Allen method,Priestley-Taylor method,and Hargreaves-Samani method,the ET0 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-79Penman method were closer to those of the FAO56Penman-Monteith method in the Ordos Plateau area.Therefore,the ET0 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 ET0 value.
