文章分析了月球复杂的重力场环境对月球卫星轨道运行的影响。通过月球卫星冻结轨道与地球卫星冻结轨道的对比分析，结果表明月球重力场存在较大异常，并由此引起月球卫星轨道发生较大漂移。另外，月球冻结轨道在带谐项影响下还存在中等周期的漂移，仅简单考虑带谐项系数无法求得完美的月球冻结系数。由于月球重力场异常对绕月卫星的影响与地球轨道卫星情况相比存在很大差异，因此月球轨道卫星的长期运行与控制策略的设计必须充分考虑此影响

The effect of lunar gravity environment on the lunar satellite orbit is analyzed. The differences between the frozen orbit for lunar and earth satellites are compared first. It is shown that the lunar gravity anomaly is responsible for a large drift to the lunar satellite orbit, the lunar tesseral harmonics are responsible for a moderate period drift to the lunar frozen orbit. Because the effect of lunar gravity anomaly on lunar satellites is quite different from the case for the earth, so for the long-term orbit operation and control for lunar satellites, a different strategy must be adopted than the traditional methods designed for the earth satellite orbit.
