摘　　要：本文从宇宙线在极区电离层电离的理论出发,分析了宇宙线Forbush下降对极区低电离层的影响,并结合南极中山站(69°24′24″S,76°22′40″E)Riometer仪器记录到的一个极夜期间Forbush下降事例,分析了宇宙线Forbush下降和宇宙嗓声负吸收之间的关系,较好地解释了Forbush下降对宇宙噪声吸收的影响。Using the ionization theory of cosmic ray polar ionosphere, the influence of cosmic ray Forbush decrease of the low ionosphere in the polar region is studied in this paper. The relationship between Forbush decrease and cosmic noise absorption during the polar night is analysed from the data recorded by a Riometer at Antarctic Zhongshan Station (69°22′24″S, 76°22′40″E). The influence of cosmic ray Forbush decrease on the cosmic noise absorption is well interpreted by the theory mentioned.
