摘　　要：利用ＥＲＢＥ和ＩＳＣＣＰ卫星辐射及总云量资料，结合青藏高原地面日射资料，讨论并提出了该地区地表短波吸收辐射的气候反演方法，该法的拟合精度较高，平均误差为９．８Ｗ·ｍ－２，据此计算出７５°Ｅ～９５°Ｅ及２５°Ｎ～４０°Ｎ间２．５°×２．５°经纬网格点和高原６３个站点的各月平均地面吸收辐射通量密度，绘制出其在高原的分布图，揭示其基本特征。In the context of 1985～1988 ERBE data and 1984～1988 ISCCP satellite albedo and total cloudiness in connection with Qinghai Xizang actinometric measurements, investigation is performed of the climatic retrieval of surface absorbed shortwave radiation (SASWR) in the research highland. Evidence suggests that the method gives higher fitting accuracy with mean error of 9.8 W·m -2 , whereupon calculated is the monthly mean SASWR flux density at the gridpoints of 2.5°×2.5° resolution over 25 °N～40 °N, 75 °E～95°E and 63 stations alongside the distribution prepared for its basic features.
