摘　　要：为解决传统载人登月方案中重型运载火箭难以研制、交会对接窗口选择困难等问题,提出了符合我国现有技术条件的基于地月L1点的载人登月方案设想。基于对圆形限制性三体模型和地月L1点特性的分析,将载人登月任务划分为不同的飞行阶段,研究了载人登月任务的规模、系统组成以及各舱段的质量分配等。通过与基于环月轨道方案各参数的分析和对比,提出通过付出较小代价将基于环月轨道的载人登月方案转化为基于地月L1点的载人登月方案的方法。结果分析表明,经方案转化,不但能充分发挥地月L1点的优势,而且在一定条件下可以使节省燃料成为可能。To overcome the difficulties in traditional flight scheme, such as heavy rockets are diffi- cult to design, and launch window can be hardly chosen, a flight scheme based on the first Earth-Lunar Lagrangian Point （ L1 ） was proposed. Based on the analysis of the circular restricted threebody model and the Earth-Lunar L1＇s characteristics, flight of the manned lunar landing mission was divided into several stages. The scale of the mission, composition of manned lunar landing system and mass estimation of each cabin were studied. With a detailed comparison with the scheme based on lunar orbit, we could find a less costly way to transform it to the flight scheme based on the L1 point. The results show that by transformation, the scheme based on L1 can not only take advantage of the merits of L1, but also consume less fuel under certain conditions.
