<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 .

An implementation of mining subsidence DEM considering landform feature;

For many years, the geomorphology research has devoted to theresearch on landform features of the large region at small scale, and theresearch on landform features and process of the small region at big scaleprogress slowly.

Through the study of geomorphical characteristics in the bordering coastal area between Shanghai and Jiangsu province, the paper provides technical results for deciding sea-area borderline of Shanghai and Jiangsu province.
