The astronomical solar radiation (ASR) over rugged terrains (RT) is closely associated with local landform besides the effect of season and latitude. The influence of slope, aspect and terrain inter-shielding on ASR is analyzed over RT. Based on digital elevation model (DEM), a distributed model for calculating ASR over RT is developed. Using this model, the ASR with a resolution of 100m×100m in the Guizhou Plateau is generated. The results are as follows. (1) The ASR has obvious terrain distributing feature over RT. (2) The annual average ASR varies spatially 481.7~13041.8 MJm-2 over RT. The average ASR varies spatially 0.0~1244.7 MJm-2 and 0.0~1264.8 MJm-2 in January and July over RT, respectively. (3) The influence of the local topographic factors on spatial distribution of the ASR varies with season and latitude. Although the solar altitude angle is lower in January than in July, which causes more inter-shielding by the RT in January, the ASR is much stronger in July than in January; the absolute difference in ASR between HS and RT is larger in July. Therefore, the effect of local topography on ASR is still marked in January and July over RT.
