摘要：

利用河北省周边8个日射站逐月日照百分率资料和太阳总辐射资料，采用最小二乘法拟合经验系数a、b，然后分别通过纬度分区和反距离权重插值两种方法得到河北省142个测站的经验系数a、b，并据此求出河北省内四个具有辐射观测数据台站的总辐射值，对比分析了实测值与不同经验系数下总辐射估算值之间的差异。结果表明：纬度分区和反距离权重插值两种方法所建立的太阳总辐射量估算公式的模拟精度总体差别不大，但采用纬度分区法所得的经验系数，在计算太阳辐射年总量时与实际观测值更为接近，因此建议采用纬度分区法计算河北省各地太阳总辐射量。

Abstract:

 Based on the monthly sunshine percentage and solar radiation data from 8 solar radiation stations surrounding Hebei province, the empirical coefficients of a and b in the climatic formula of total solar radiation were calculated by a least-squares method. These coefficients were then obtained for 142 stations in the whole province using methods of a latitude partition and an inverse distance weighted interpolation. The total solar radiations at four solar radiation observational stations were calculated using the above empirical coefficients and the results were compared with the observation. The comparisons have shown that the accuracies of the two methods are similar. However, the annual total solar radiation calculated using the latitude partition method is closer to the observation. Thus, this method is recommended to use for estimating the total solar radiation in Hebei province.
