利用江苏省南京、吕泗、淮安3个日射站以及周边省市共10个日射站逐月日照百分率资料和太阳总辐射资料,利用最小二乘法拟合经验系数a、b,并利用除南京、吕泗2个日射站以外的8个日射站的经验系数a、b,采用多种插值方法计算江苏省70个站的经验系数a、b,并据此求出70个站点逐月太阳总辐射值并分析其分布特征。结果表明：采用反距离权重插值法得到的经验系数a、b,误差最小。结论可为求解江苏省各地太阳总辐射提供科学参考。

Based on the monthly sunshine percentage and solar radiation data from 3 solar radiation stations（Nanjing,Lvsi and Huai′an stations） in Jiangsu province and from 7 other solar radiation stations in surrounding provinces,the empirical coefficient a and b were calculated by a least-squares method.The empirical coefficients a and b for about 70 stations in the whole province were obtained by various interpolation schemes.Then the characters of the monthly total solar radiation and its distribution were obtained.The results indicate that the empirical coefficients a and b determined by the inverse distance weighted interpolation method have the least errors among various interpolation schemes.The conclusion could provide scientific references for calculation of solar radiation of Jiangsu province.
