摘　　要：结合常规气象资料，给出了一个较为简单的而且计算误差相对较小的紫外辐射计算方法，计算了五道梁地区的紫外辐射，给出了五道梁地区1957～2000年间的紫外辐射序列。分析发现：五道梁地区冬、夏季节季平均紫外辐射有减小的趋势，冬季减小的趋势较夏季明显；年平均紫外辐射瞬时辐照度略有减小的趋势；紫外辐射10a变化分析发现，70年代紫外辐射为大值，90年代为次大值，60年代、80年代为小值；月平均紫外辐射冬季小、夏季大，3—5月份紫外辐射急剧增大，9-11月份紫外辐射迅速减小。A simple method with little calculated error was given to compute the ultraviolet radiation （UV）. With such a method, UV over Wudaoliang was calculated, and long period UV sequence was given. Some conclusions were drawn by analyzing the UV result, that there is a decrease tendency during the winter and the summer, but this tendency in winter is more obvious than in summer; there is a little decrease tendency for the annual mean instantaneous UV irradiance; the UV value in the 1970s is the largest, in the 1990s the second big and the value in the 1960s and 1980s is small; monthly average UV instantaneous irradiance is big in summer and small in winter. UV increases violently during the spring and decreases rapidly in autumn.
