It can be divided into two parts. The western part is West Sichuan High Plateau and the eastern part is Sichuan Basin. The boundary between the two parts is equally about the eastern boundaries of the three autonomous prefectures. The faunal composition (Zhao, 1999) of Sichuan reptiles is more complex. In general, the north part of the West Sichuan High Plateau is dominantly Hengduanshan Palearctic Element, the south part of the West Sichuan High Plateau is still Hengduanshan Palearctic Element on high mountains, but in low mountain and deep valley are Hengduanshan Oriental, Himalayas , and Himalayas Hengduanshan elements, but also invaded by Southern China, Indochina , even Indo Malayan elements. In eastern part of Sichuan Province, the Sichuan Basin, is mainly Southern China Element, while its western border mountains mainly Hengduanshan Oriental Element. A cosmopolitan species, Ramphotyphlops braminus , was also found in Middle Sichuan Basin Plain and Hill Province (Chongqing City and Nanchong). The Sichuan Province can be, zoogeographically, divided into six regions, i.e., Northwest Sichuan High Plateau Province (ⅣB4), Southwest Sichuan High Mountain and Deep Valley Province (ⅤA4), Sichuan Basin West Border Mountain Province (ⅤA5), Sichuan Basin Northeast Border Mountain Province (ⅥB1), Middle Sichuan Basin Plain and Hill Province (ⅥB2), and Sichuan Basin Southeast Mountain Province (ⅥB3).
