The study was focussed on thered beds in Sichuan- Yunnan region, representativeof southwest China and the red beds in Gansu, the representative of northwest China, the geologic environment characteristics of the red beds, such as the geostructural characteristics, geomorphic characteristics, climatic en- vironment characteristics etc. were studied. According to thegeologic environment characteristics, the red beds in Sichuan- Yunnan region are zoned into those in Sichuan basin, Xichang Dianzhong, Dianxi and Gansu.
