国际月球科研站（International Lunar Research Station，简称ILRS）的建立是我国顺应当前形势的重要太空战略部署。为研究基于多源数据的形貌分析在ILRS建设过程中的应用，将“ILRS计划”分为选址和科考阶段。分析ILRS选址阶段需考虑的约束条件，简述正射高分光学影像、月表地形、 月球DEM、激光高度计、微波辐射计、多/高光谱成像、测月雷达、伽马射线等多源数据在选址阶段的应用，利用嫦娥二号DOM、DEM、LRO Diviner辐射计、LOLA激光高度计以及地质制图等多源数据对月球南极地形特征、温度条件、光照条件、对地能见度和地质特征进行分析，提出在ILRS选址阶段应考虑的诸多因素和适合着陆选址的区域特点，并以Amundsen区域为例，选择了3个候选着陆点。以Shackleton、Shoemaker、de Gerlache和Amundsen撞击坑为代表，基于多源数据分析结果为ILRS科考阶段巡视路线的规划、水冰探测的分析、观测基站的设立提供参考。研究表明基于多源数据的形貌分析结果对ILRS的选址和科考任务都有重要参考价值。

The establishment of the International Lunar Research Station (ILRS) is an important space strategic deployment for China that conforms to the current situation. The moon is an important part of deep space scientific research that cannot be ignored. Exploration of the Moon marks a country"s space capability. Cooperate in lunar exploration and utilization, and build a lunar research station, so as to better improve human welfare and interests. China"s lunar exploration is moving from independence to win-win cooperation. Chang"e-4 has created a new situation for the first time in which China plays the leading role in promoting multinational cooperation in joint Chinese and foreign exploration. In 2021, based on the existing Exploration of the Moon plans of China and Russia, China National Space Administration and Roscosmos jointly launched the ILRS project. In order to study the application of topography analysis based on multi-source data in the construction of ILRS, the "ILRS plan" is divided into site selection and scientific research stages. Analyze the constraint conditions to be considered in the site selection stage of ILRS, briefly describe the application of orthophoto, lunar surface topography, multi/hyperspectral image, lunar radar, gamma rays and other multi-source data in the site selection stage, and use the multi-source data of Chang"e-2 DOM, DEM, LRO diver radiometer, LOLA laser altimeter and geological mapping to analyze the topographic characteristics, temperature conditions, lighting conditions, the earth visibility and geological characteristics. Many factors that should be considered in the ILRS site selection stage and the regional characteristics suitable for landing site selection are proposed. In order to achieve the scientific goals of ILRS, the landing area should have conditions such as gentle terrain fluctuations, less changes, suitable lighting and temperature, and convenient water ice detection. Taking the Amundsen area as an example, three candidate landing sites are selected. Based on the best Decision model and multi criteria Decision model, qualitative and quantitative decision analysis is carried out for the three candidate points proposed in this paper. Taking Shackleton, Shoemaker, de Gerlache and Amundsen impact craters as examples, based on the analysis results of multi-source data, it provides a reference for the planning of inspection route, the analysis of water ice detection and the establishment of observation base stations in the ILRS scientific research phase. The shape of the Impact crater in the study area affects the planning of the inspection route. When setting the inspection route, the area with complex and changeable shape of the Impact crater should be avoided. The permanent shadow area in the large Impact crater should be emphatically analyzed to ensure the successful realization of water ice detection and reduce the risk and resource waste caused by misjudgment. Areas with higher visibility to the sky and ground are more suitable for establishing observation base stations to ensure the continuous and stable progress of observation tasks. The research shows that the topography analysis results based on multi-source data have important reference value for ILRS location and scientific research tasks.
