| 摘 要： | 对全国23个站点的日照时数、日最高气温、日最低气温、太阳日总辐射量等气象要素实测资料进行统计分析，利用回归分析法建立了以日照百分率和气温日较差为主要相关因子的各地日总辐射估算模型。结果表明：除了高原站拉萨以外，推算模型的复相关系数均介于0．80～0．93之间，拟合效果较好。在春、夏季使用独立的季节模型有一定的必要性，该方法适用于我国各地太阳日总辐射的推算，

| Abstract: | By analyzing daily observed routine meteorological variables such as sunshine-hours, maximum temperature, minimum temperature and solar radiation from 23 stations in China, models were established for assessment of daily solar radiation. The models include two independent variables i. e. percentage of sunshine and diurnal temperature range. Except for Lhasa weather station with a high elevation located in plateau, multiple correlation coefficients of all models range from 0.80 to 0. 93. Through analysis on the modeled results, we found that it is necessary to use seasonal models to estimate daily solar radiation,especially for spring and summer. It could come to a conclusion that the models developed in this paper are effective and feasible in the assessment of daily solar radiation in whole China. |
