Based on the reversible and tracking record characters of the earth satellite remote sensing data for the observed object, the 20-years(1985—2005) consecutive monitoring on the Goulucuo Lake, located in the hinterland of Qinghai-Xizang (Tibet) Plateau, was carried out. The long time observation records and the continuous variation sequences were built up. The motion phenomenon and the self-organizing dissipative structure of the natural evolution process of the lake water were deciphered. The random evolution process and the motion locus of the lake were depicted with the employment of the system attractor and the fractal dimention. The motion process and the geodynamics mechanism of the dynamic change of the lakes in Qinghai-Xizang (Tibet) Plateau region were expounded. The results may provide information for the scientific recognition of the responding events to the climate environment recorded by the inland lakes and global change analysis.
