摘　　要：利用遥感数据对观测对象的可逆及追踪的记录特性,对青藏高原腹地苟鲁措湖泊进行了20余年(1985—2005年)的连续监测,建立了长时相观测记录及连续变化序列,破译了湖水自然演化过程的自组织耗散结构及运动现象,采用系统吸引子及分形分维演绎刻划了湖泊随机演化过程及运动轨迹,从而阐明了青藏高原湖泊动态变化的地球动力学机制及运动过程,为科学认识大陆湖泊记录的气候环境响应事件及全球变化分析提供客观自然的变化信息。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.
