摘　　要：考虑天气情况对入射太阳辐射的影响,研究和分析日照时数、天气类型和辐射参数的关系,并将散射模型、透射率和散射比例与4种常用天气类型相对应。以佳木斯市辖区为例,采用ArcGIS的点太阳辐射分析批处理工具,对佳木斯辐射台站进行日入射太阳辐射分析。通过将默认情况和天气类型两种模拟结果与辐射台站的实测值进行分析和验证,获得两者的相关性R2分别为0.573 4和0.899 5。研究结果表明按不同天气类型进行中温带地区点太阳辐射分析的方法切实可行,并获得更好的点日太阳辐射模拟效果,其有利于研究不同天气类型下物理和生物过程模型所受到的太阳辐射影响。Considering the influence of the weather conditions to oncoming solar radiation ,this paper analyzes the relation among the sunshine time ,weather types and radiation parameters ,then divides them into 4 types of common weather（perfectly clear ,generally clear ,generally cloudy and perfectly cloudy ） . Diffuse model ,diffuse proportion and transmittivity correspond to the different weather types . Taking Jiamusi prefecture as an example ,it uses the points solar radiation batch analysis tools in ArcGIS and analyzes the daily incoming solar radiation of Jiamusi radiation station .Compared two kinds of simulation results of the default and the weather types with the Jiamusi radiation measured values in the station ,the correlation of both R2 of 0 .573 4 and 0 .899 5 are respectively through the analysis and verification .The results show that the point solar radiation analysis method according to different weather types in temperate regions is feasible and obtains the better daily solar radiation simulation than the default .T he results can be beneficial to physical and biological processes model as affected by the sun under different weather types .
