| 摘 要： | 利用阿克苏地区1975-2004年的逐日气象资料，分别采用Penman—Monteith公式与Penman修正公式计算了新疆农一师灌区的参照作物腾发量及其辐射项和空气动力项的逐日均值和旬日均值，比较了2种计算方法的绝对偏差和相对偏差，并对引起偏差的原因进行了分析。

| Abstract: | Based on the daily meteorological data in Aksu area from 1975 to 2004,the multi-year mean value for each day and the value for each ten days of the reference crop evapotranspiration,the radiation item and aerodynamic item in Xinjiang Nongyishi irrigation district were calculated by Penman-Monteith Equation and Modified Penman Equation.Then,the absolute deviation and relative deviation of the above indices between two methods were compared.Also,the main cause of the deviation was analyzed. |
