Protection of the diversity of river morphology character;

Generally, the effect of Coriolis force on the river morphology in low latitude regions is not so much noticed as that in the high latitude regions.

According to 2000 year s RS images,this paper explains the river geomorphology and draws the explanary picture after analyzing the primary components,multiband image integration,gray bar statistics,etc.

According to many researchers achievement, the response of fluvial geomorphology to tectonic movement is discussed.

<Abstrcat>The geomorphological characteristics,palaeoenvironment and paleoculture of the Chengdu plain are studied,also the relationships between them, which is helpful to understand the process of development of the paleoculture more deeply and realize that the paleoculture has close relationship with the geomorphological characteristics and palaeoenvironment.

In this paper,we take Xiaoshan-Qiuchuan Faults as an example,the detailed rupture character is analyzed from a viewpoint of geological and topographic features,and .
