研究了青海云杉林的辐射平衡，表明青海云杉林林冠辐射平衡各分量在总辐射中所占的比例为：反射辐射１２．０７％，净长波辐射２９．４６％，净全辐射５８．４７％，辐射平衡各分量与总辐射线性回归，相关紧密；青海云杉林林内总辐射比林外减少７１．０２％，林内净辐射变幅小于林冠层．
The radiation balance of Picea crassifolia forest was studied. The results showed that the proportion of the radiation balance in the canopy of Qinghai spruce forest was 12.07% of the total radiation, 29.46% of the net longwave radiation and 58% of the total net radiation. 47%. The components of the radiation balance are closely related to the linear regression of total radiation. The total radiation in the spruce forest in Qinghai Province decreased by 71.02%, and the net radiation amplitude in the forest was less than that in the canopy.
