A fractal and statistical analysis of mountain ranges and faults has been made respectively for southwest China and the whole continental area of China It is found that the fractal dimension is 1 63 for mountain ridges in continental area of China, and 1 35 for those in southwest China.

Based on the fractal and statistical analyses of mountain ridges in southwest China and the whole continental area of China,the characteristics of mountain ridges are discussed.

that in Yinshan mountains and Hu-Bao Basin area, there not exist obvious concave and convex at Moho discontinuity, as well as the northern margin of Hu-Bao .

In Yinshan mountains and Hu-Bao Basin area, the bottom of the crust lays shallower.

Landscape pattern analysis of red panda habitat in Liangshan Mountains;

In 1975-1991 an extensive investigation on giant pandas was conducted in Liangshan mountains and an observation station was set up in Mabian Dafengding Natural Reserve to monitor them.

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.
