摘　　要：介绍5种根据水平面太阳总辐射、直接辐射、散射辐射和太阳天顶角计算南向倾斜面太阳总辐射的数学模型。利用云南省丽江地区太阳辐射观测数据,计算南向纬度倾斜面太阳总辐射值,与同期纬度倾斜面太阳总辐射观测值进行比对,并以观测值为参考,对由5种模型计算的纬度面太阳总辐射值作统计分析。结果显示:5种南向倾斜面太阳总辐射计算模型均能较好地计算出丽江地区南向纬度面上的太阳总辐射值。其中,Hay模型最适合于在不区分天气状况的条件下使用,Ma-Iqbal模型最适合于应用在阴天和多云天气状况下,而晴天条件下则最好选用Muneer模型。Five models for calculating the global solar radiation on a surface tilted to south using global horizontal radiation, direct radiation, horizontal diffuse radiation and the solar zenith angle were presented, which were used to calculate the global solar radiation values on latitude degree tilted surfaces to south based on the solar radiation observations Lijiang in Yunnan province, then using the global solar radiation measured correspondingly on a latitude degree tilted surface to south as the reference, the radiation values calculated by the five models were compared with the collected value, respectively. According to the statistical analyses on global solar radiation on a latitude degree tilted surface to south measured in Lijiang and global solar radiation values calculated by five models, the Hay model is the most suitable for using in all weather conditions, and the Ma-Iqbal model is the most suitable for applying in overcast and cloudy sky conditions, and it is the best for clear conditions to use Muneer model.
