• 摘要：建国以来, 福州由于市区范围不断扩大及工业发展, 人口和车辆与日俱增, 空中尘埃量随之增多, 空气日益恶浊.这种状况势必改变大气和地面辐射过程, 导致太阳总辐射减少和散射辐射增多以及能见度恶化.本文仅通过福建省气候中心30年(1961-1990)气候资料整编的太阳辐射、日照、能见度、轻雾以及大气混浊度的分析来说明福州大气污染的年代变化和发展趋势, 以引起有关部门的关注.

• Abstract：In order to reveal the variation characteristic of air pollution in Fuzhou, the climate tendencies of the solar radiation and other elements for mote than 30 years were calcuated and analysed in this paper.Through analysis, we found that there existed a decreasing tendency of global solar radiation flux, direct solar radiation flux, sunshine and good visibility with the passage of years, while it followed the marked increasing phenomeonon of scattered radiation and turbidity factor.At the same time, these kinds of variations will go on with the development of the city.

• Key words：global solar radiation  scattered radiation  visibility  turbidity factor
