将常见的18个水平面日太阳散射辐射模型分为5类,利用上海气象台站数据,通过统计学参数、残差直方图比较18个模型的准确性.分析结果表明,文献中的Lam&Li模型、苏华和田胜元模型、Liu&Jordan模型、CLIMED1模型、Boland模型2*计算出的散射辐射较为准确,更适合上海地区使用.同时,根据这5类方程的构建方法,用上海地区近20a实测辐射数据建立5个相应的拟合方程(MDF1～MDF5).用30a的辐射数据对比分析这些模型的准确性,结果表明CLIMED1模型和MDF2模型与实测值更吻合,其中MDF2模型的准确度最高.对于上海及相似地区,在缺少长期辐射观测数据的前提下,建议采用CLIMED1模型进行散射辐射计算；否则建议根据该文结果自建拟合方程,这样精度更高.
