In this paper. the kinematic features of Himalayan orogeny of the thrusting eastwards, the strike-slip faultings and the thrusting southwards, are described briefly, which has resulted in crustal shortening in both latitudinal and longitudinal directions. To strip the reformation of Himalayan orogeny and to restore the Panzhihua-Xichang Graben system and the Central Yunnan Trough to their original position (the Chuxiong Basin is regarded as in situ), the tectonic evolution of the bordering area of Sichuan and Yunnan is illustrated in the light of orogenic process (the Paleotethysides was created) and coupled basin developing. Although the Yanshanian orogeny took place, the orogen-basin relation set up in the Indosinian orogeny was not decoupled untill the Himalayan orogeny. All the three deformational episodes are reflected in the Chuxiong Basin, which took its shape, as a structural basin, during the Himalayan movement. The reformation was further strengthened by neotectonic activities which inherited the Himalayan structural modes. Based on the decoupling expressions, the unfavourable factors for the Chuxiong Basin's preservation and oil-gas accumulation are analysed.
