中文摘要	为了寻找适合浑善达克沙地参照作物腾发量计算的简易方法,该文以实测的微气象数据为基础,分别采用FAO56 Penman-Monteith(1998)、Hargreaves-Samani(1985)、Irmark-Allen拟合以及Priestley-Tay-lor(1972)计算参照作物腾发量,并以普适性强、精度高的FAO56 Penman-Monteith为基准,对其他方法进行气象因子的非线性修正。结果表明:气象因子修正后的参照作物腾发量精度大大提高,为获得相对可靠的参照作物腾发量开辟了新的途径。FAO56 Penman-Monteith、Irmark-Allen拟合和Priestley-Taylor都需要用到净辐射,而专业测量净辐射的设备在农业气象站里很少安装,使三种方法推广使用受到一定限制。气象因子修正后Hargreaves-Samani需要的气象数据相对容易获得,且计算简单,具有较高的精度,建议在缺少气象资料的干旱地区推广采用。
英文摘要	In order to obtain the proper calculation methods for reference crop evapotranspiration (ET0) in the Otindag sandy land,FAO56 Penman-Monteith (1998),Hargreaves-Samani (1985),Irmark-Allen and Priestley-Taylor (1972) were used respectively to estimate the reference crop evapotranspiration based on the micrometeorological data,and other three common formulas were adjusted to compare with FAO56 Penman-Monteith,which universality is strong and has high precision. The results show that accuracy of adjusted reference crop evapotranspiration is greatly improved. Which Provides a new simple way for reference crop evapotranspiration calculated. Net radiation measuring devices,which requiring professional control has rarely been installed in agro meteorological stations,but the FAO56 Penman-Monteith,Irmark-Allen and Priestley-Taylor need the net radiation, so they have some restrictions on using. Meteorological data adjusted needed by hargreaves-Samani is relatively easy to obtain and calculate,and with high precision.
