| 摘 要： | 利用成都、乐山、内江和雅安在1951--2000年的气象资料和地理参数，用Penman-Monteith公式计算蒸发蒸腾量（ETo），将双线性理论用于EL的计算，建立了多个计算ETo的双线性模型，进一步利用双线性模型计算的E丁0再建立双线性模型，在已建立的双线性模型基础上，又建立了简化双线性模型。各双线性模型与P-M计...

The Reference Crop Evapotranspiration Estimation Based on Bilinear Theory |

| Abstract: | According to the meteorological data and geographical parameters in 1951—2000,calculating crop the evapotranspiration(ET0) for Penman-Monteith model.Calculated of the ET0 in the bilinear theory,establishing the calculation of ET0 calculated by bilinear model,and to further utilize step bilinear model establishment of ET0 calculated by bilinear model,by analogy,establishing the simplified bilinear model.Through comparing the relative error of the absolute value of mean and the root-mean-square error with the different bilinear model,the bilinear model precision is high.Through mean absolute error and the average relative error are smaller in the simplified bilinear model.Therefore,in practice,we may use the simplified bilinear model for calculation of the ET0 calculated based the precise demand. |
