摘　　要：根据大同市辐射、日照条件变差、烟幕日数增多等事实,利用大同市1963—1987年地面实测的太阳辐射资料分析了大同空气污染对太阳辐射的影响及其长期变化情况。结果表明,到达地面的太阳辐射量的减弱与空气中混合污染物的影响有较密切的关系;空气污染物对太阳辐射量减弱的逐年变化情况,与混浊度因子的变化有很好的相关关系。Based on the facts that the solar insolation and sunshine condition in Datong is getting worseand the smoke screen days is more than before,the influence of air pollution on solar insolationand its variation in Datong are estimated by using the observational data of surface solar insola-tion from 1963 to 1987.It is shown that the decrease of solar insolation is greatly related to theinfluence of mixing pollutants and there is a good correlation between the annual variation of so-lar insolation and the turbidity factor.
