Abstract: With the further development of lunar exploration,the construction of lunar base is taken by many lunar exploration schemes and lunar development plans at home and abroad as an important goal. The lunar base will serve the future unmanned lunar exploration and manned lunar missions. The function and significance of the lunar base are analyzed. According to the carrying capacity of China's rockets,a scheme for the lunar base construction is put forward,which includes the preliminary concept of the location constraint,the construction steps and the implementation process of the lunar base. The typical detection station and devices of the lunar base are analyzed. Some key problems of the lunar base are discussed,which will provide reference for the construction of the lunar base in the future.
