英文摘要：

This paper introduces the distribution and development characteristics of the landslides in Bazhou Dis-trict, Bazhong city of Sichuan province after 5.12 earthquakes. The geological environment background connect-ing to their occurrence and development are analyzed. Mainly attention is put on the relationship between land-slides and rock structure, also the basic rule of landslides development. With special examples, we proposed the classification system of landslides formation mechanism that earthquake triggered. Finally, we summarized five main types of landslides and generalized their basic characteristics and geological models.
