Abstract: Landing site selection is an important part of the design of an exploration mission. The correctness of site selection result directly determines whether the detector can successfully complete the mission, and also determines the important basis for the design of each sub-system in the program design process. In this paper, the site selection method of the lunar south pole exploration landing area was introduced, the topography and illumination characteristics of the lunar south pole were analyzed, the principle of site selection was formulated, the influencing factors and constraints of site selection were analyzed in detail, and introduces the engineering the site selection method using coarse-to-precise strategy, combined with the site selection results, and 5 landing sites were selected initially, which will provide reference for the design of future lunar exploration missions.
