In thi s paper .the characteristics of the radiation budget over two types underlying surface are analyzed by using the data observed in oases (Zhangye)and desert in HEIFE.  The results show that:in the arid region .the surface albedo is smaller in oases than in desert and its seasonal variation is obvious.  The surface ipward longwave radiation is also smaller in oases than in desert.the effec tive radiation is smaller in oases than in desert and its seasonal variation is obvious .too.  The surface net radiation is lager in oases than in desert and the energy from surface to atmosphere is latent heat mainly.  The annual total of Photosynthetically Active Radiation (PAR) is larger over oases in arid region than that in Hebei and Shandong.  In arid region the PAR resource is very rich.
