摘要
本文利用 1998年 1— 12月太湖湖泊生态系统研究站的太阳辐射观测资料进行分析 ,得到此间太湖地区近地面太阳紫外辐射及其占太阳总辐射比例的变化特征。结果表明 :该地区太阳紫外辐射年平均日总量为 0 .73MJ· m-2· d-1,大于临近的上海 ;紫外辐射瞬时极大值为 5 0 W· m-2 ;紫外辐射在总辐射中所占比例年平均值为 6 .2 % ,也比上海要大 ;其年变化特征与上海相同 。
The variation characteristics of solar ultraviolet radiation near the ground in Taihu region are analyzed by using the observational data of the solar total radiation and ultraviolet radiation in Taihu Laboratory for Lake Ecosystem Research from January to December in 1998.The results are as follows:The annual mean daily total ultraviolet radiation is about 0.73MJ/m 2,larger than that in Shanghai neighborhood.The instantaneous maximum of ultraviolet radiation is 50W/m 2。The annual mean ratio of UV to Q is about 6.2%,also larger than that in Shanghai.The annual variation characteristics of UV in Taihu region are the same as those in Shanghai.
