The site selection strategy of manned lunar base is a complex system selection process and many factors should be considered including the project mission objective , science objective , Engi-neering capacity constraints and resource utilization .This paper investigated the site selection of manned lunar exploration and the principles of manned lunar base selection of foreign countries , In addition , the science and engineering objectives were also evaluated .The basic principles of lunar base site selection and influencing factors were assumed macroscopically .Based on the special lunar surface environment and the restriction of lunar base construction , different kinds of restrictions of manned lunar base site selection were analyzed .In the end , consulting the landing site of unmanned and manned lunar exploration , Sinus Iridum , Marius and Cabeus were elementarily selected as can-didate sites and studied in detail in this paper .%载人月球基地选址有许多因素需要考虑，如战略意义、科学目标、工程能力约束和资源利用等。分析了国外载人登月着陆点选取及月球基地选址原则，确定了各种选址影响因素的优先级，为我国载人月球基地选址提供了参考依据。基于月球表面的特殊环境和月球基地建设过程中的工程能力约束，对载人月球基地选址约束进行了分析。结合国内外无人月球探测工程、载人登月工程选址点的分布情况，初选月球正面的虹湾、月球赤道的马留斯地区和南极Cabeus撞击坑进行了载人月球基地选址综合分析。分析结果表明，具有较好科学研究意义的虹湾地区和可能存在水冰资源的Cabeus撞击坑均能够满足载人月球基地的选址需求。
