    The daily and seasonal variation characteristics of the solar ultraviolet at Lhasa and Nagqu are analysed by using the observational data of the solar ultraviolet over the Qinghai-Xizang Plateau during August 1982 to July 1983.The results are as follows: The solar ultraviolet on the Plateau is very strong, the annual total is more than 63 kilocal·cm-2.The ratio of the solar ultraviolet to the global radiation is about 4.0-4.1%. This ratio is about 4.8-4.9% for cloud sky,and it is larger than the ratio in clear sky. The seasonal variation of the solar ultraviolet is very outstanding, in summer the total is more, than 1/3 of the yearly total and in winter the solar ultraviolet is weaker than another season, the total is only 17% of the yearly total.The radiant flux of the solar ultraviolet on the Plateau is 1.3 times as large as MoHe on the plain in the north-eastern part of China.The instantaneous maximum of the solar ultraviolet reaches to 0.100 cal·cm-2 ·min-1.
