【Abstract】 The present paper deals with the characteristicts of the radiation in loess plateau of China, The auther has obtained the following points of view:1. The annual total radiation is 115-160 kcal/cm², the maximum of annual variation occuss in June, and the minimum in December, The net radiation is 43-58 kcal/cm².2. The sunshine duration and amount of solar radiation for various slopes in loess plateau are given in tables 4—7.3. Based on the data of radiation observed from May to Augaust 1979 in Qinghai-Xizang Plateau, the auther has obtained the formula which may be used to various altitude, i. e.F_p=F_op(1-0.45n_hm-0.71n₁)[1.572-0.689（（（P-550）/（P₀）））^0.2]F_op=[δσT₀^?-δσT⁴(0.63-0.03n+0.05(2^1/e][1.984-1.004（P/P₀）^0.8]This formula is capable to be used in loess plateau.更多还原
