Abstract: Based on the available data from a couple of existing lunar probes, comparison is made of the landing environments such as the terrain, the slope, the illumination, and the cater distributions among the lunar low latitude area, the south pole and the north poles. It is shown that the lunar poles are featured with larger elevation changes and lower average temperature; besides, the terrain and slope conditions are more complicated in the south pole than in the north pole, which pose a threat for the polar landing process. In addition, the area of the largest permanently shadowed regions (PSRs) and their density are all greater in the south pole, and the PSRs are well known as the most possible enriched position of the ice water. The area of long term illumination regions is bigger in the south pole, to provide sustained power during local exploration. In conclusion, we suggest that the south pole is the most appropriate region to implement lunar exploration for higher scientific significance of detection and engineering convenience of exploration.
