摘　　要：针对GEO(Geostationary Earth Orbit)在轨及附近空间的碎片,首先分析了不同面质比光压摄动的量级,并给出一年内地影的分布情况,然后推导适合GEO的春分点根数的拉格朗日摄动运动方程,从动力学角度分析面质比对轨道的影响,最后给出相应的数值验证,证明了空间碎片的面质比与光压摄动对轨道的影响成正比。In view of GEO （Geostationary Earth Orbit） and near space debris, firstly orders of light pressure perturbation with different area-mass ratio are analyzed, and distribution of eclipse in a year is given. Then Lagrange perturbation mo- tion equation in equinoctial elements is derived. The influence of area-mass ratio on orbit is analyzed in view of dynamics, and simulations are given to prove it. It is proved that area-mass ratio of space debris is in proportion to the solar pressure perturbation influence on orbit.
