摘要： 青藏高原以其平均海拔高度（约4000米）最高闻名于世。由于海拔高度的影响,空气稀薄,大气干洁,太阳辐射透过大气损失和被吸收的也少,因此,这里的太阳年总辐射量高居全国之冠,年总辐射量多在140—190千卡/厘米2,比起我国东部平原地区多60—80千卡/厘米2。

Abstract: In this paper, atmospheric turbidity and extinction property in the Xizang Plateau during the warm season are discussed. It is found that the index of aerosol particle a is 1.9, and that the aerosol’s radius on the Xizang Plateau is twice as many as in the plain of Bast China. Turbidity coefficient ?changes obviously with the elevation and season, and the same trend for transparency of atmosphere is revealed also. It shows that the atmospheric turbidity in the Xizang Plateau is determined by vapour and areosol, and Rayleigh scattering- and others are not the main factors.
