A PRELIMINARY STUDY ON FLUVIAL PROCESS AND URBAN LANDFORMS DEVELOPMENT IN CHENGDU

根据地层、文物考古以及^(14)C资料,初步探讨了围绕成都市区的锦江与府河近万年来的变迁与成都市地貌的演变过程.

Fluvial process in one of the most ,active geomorphoiogical exogenous.

In this paper, the riven courses changing of Jin Jiang River, and Fu He River through the central of Chengdu City since last 10000 years., and the urban landforms developing have been analysed.
