Integrating study the relationship between basin-mountain system and oil and gas pool forming process is one of the frontier research fields in the study of continental geodynamics,and also is a key problem of petroleum exploration in China.

Therefore, analysis of the architecture and tectonic evolution of the basin-mountain system in Sichuan Basin and its adjacent areas would be very important to gain a deeper understanding of the tectonic framework of and petroleum reservoir distribution in Sichuan basin.

The mountain-basin system(MBS) in the north of the Tianshan Mountains consists of mountain vegetation vertical belt system and concentric circular vegetation (geologic and geomorphic) system of desert basin.
