| 摘 要： | 全月面到达是21世纪以来载人登月研究的主要目标之一。影响月面可达区域的因素有很多，而阳光入射角约束和转移轨道约束是主要因素。首先分析了不同纬度区域阳光入射角规律，其次建立了一种适于月面可达区域分析的双二体圆锥曲线拼接算法，分析了自由返回轨道和混合轨道月面可达区域，并计算了变轨策略及其速度增量关系，为未来实现载人登月月面着陆区选择提供参考。

| Abstract: | Lunar global access is one of the main goals of manned lunar landing mission in the 21 st century .The sunshine incidence angle and translunar orbits are the main factors influencing the lu-nar reachable region, although there are many others.First, the sunshine incidence angle of dif-ferent latitude regions was analyzed .Then a double two-body conic model suitable for analyzing the lunar capable region was established.The reachable region of the free-return orbit and hybrid orbit was analyzed and the relationship between the orbital maneuver strategy and speed increase was calculated.The results can serve as a reference for manned lunar landing region selection in the future. |

| Keywords: | manned lunar landing reachable region of lunar surface free-return orbit hybrid orbit |
