四川地貌格局的形成及其特征——研制四川省1:1000000地貌图的体会

THE FEATURES AND EVOLUTION OF THE LANDFORMS PATTERN IN SICHUAN-Some Knowledge in Compiling the 1:1000000 Gcomorphological Map of Sichuan Province

将四川地貌格局分为三大单元:东部的四川盆地,西部的高山高原和西南部的中山宽谷,并分析了这三大单元的地势差异、地貌结构和发育过程.作者认为,新构造运动形成的构造地貌,决定了四川地貌的宏观格局.

This paper divides landforms in Sichuan province into 3 geomorphical parts: the Sichuan basin in the east part, high mountains and plateau in the west part, and mid-mountains and wide-valley in the southwest part, and analyses their differences of relief, structures of landforms and evolutional process. The author holds that the landforms pattern in Sichuan is established by tectonic landforms that formed in the neotectonic movement.
