摘　　要：分析了较高轨道(a>10000 km)大面质比空间碎片的轨道动力学演化问题.重点讨论了位于地球同步轨道的空间碎片轨道演化问题,并给出轨道偏心率随时间演化的表达式.通过进一步分析得出,倾角大于63°26′的GTO轨道空间碎片,仅在J_2和第三体摄动影响下,会出现轨道偏心率升高;而对于大面质比空间碎片,在J_2项和太阳光压同时作用下,当近地点指向的角变率与太阳平黄经变化率接近时,会出现长期共振现象,导致轨道偏心率升高,近地点降低.分析还得出,轨道演化过程中,偏心率的最大值与初始轨道近地点的指向有关.Dynamical evolution of high area-to-mass ratio debris in high orbit （a 〉 10000km） is analyzed, especially the geosynchronous orbit. The analysis provides a formulation of eccentricity variation by Kozai＇s method. According to the formulation, for GEO debris with inclination bigger than the critical inclination （63°26＇）, large eccentricity during evolution can be caused just under the influence of third body gravity and J2 term effect. And for debris with extremely high value of area-to-mass ratio, under the influence of radiation pressure and J2 term, resonant phenomenon occurs when the secular rates of the direction of the eccentricity vector caused by J2 term effect and the direction of the solar ecliptic longitude are close, and there is a relationship between the initial direction of the perigee and maximum value of the eccentricity during the evolution.
