This article is a summary of the regional geological data since the foundation of the Nujiang, Lancangjiang and Jinshajiang areas by using the theories and methods of geomechanics. The full text is divided into five parts. 1. Summarize the sedimentary characteristics of the area and its reflection of the sea water advance and retreat and the sea-land transition; 2. Analyze the magmatic activity and metamorphism and the crustal structure evolution; 3. Describe the regional tectonic features and their formation and development history ; 4. Divided the regional tectonic system, elaborated the characteristics of various tectonic systems and their formation and evolution history; 5. Discussed the tectonic movement division and tectonic movement program, and analyzed the tectonic movement origin.
