On the basis of the analysis to the merits and demerits of common empirical formulae, this paper presents a discussion result for the computation method of effective radiation.According to a simple physical consideration, we advance here some new empirical formulas for computing the total quantity of the effective radiation of Qingzang Plateau at arbitrary periods through the comparison of some other computing schemes.Our proposed formulas have the merits in definite meaning, simple computation and higher precision.It is most suitable for popularizing their use for the work on plateau.By the use. of the newly presented formulae,computation and sample diagrams are readily made for the effectrve radiation in daily total as well as in totals of three days, pentad, decade and a month.
