摘　　要：月球是人类深空探测的首要目标,而月球的内部结构则是我们了解月球与地月系形成与演化的重要窗口.相比于其他物理场,月球重力场模型具有全球均匀覆盖、精度和分辨率持续提高的特点,在月球内部结构研究中扮演着重要作用.本文对月球重力场在月球内部结构研究中发挥的作用进行了论述,包括月壳、月幔以及月核,其中重点介绍了高阶次重力场模型对浅层结构的研究贡献.进而,讨论了利用月球重力数据反演内部结构中面临的若干问题.最后,对借助重力场模型开展月球内部结构研究的应用前景进行了总结与展望.The Moon is the primary target of human deep space exploration. The internal structure of the Moon is an essential window for us to understand the formation and evolution of the Moon and the Earth-Moon system. Compared with other geophysical fields, the gravity field model of the Moon plays an important role in the investigating of its interior structure because of its global uniform coverage and continuous improvements on its resolution and accuracy. This paper addresses the scientific applications of the lunar gravity field to investigate the Moon’s internal structure. The role played by the lunar gravity data in lunar internal structure study is discussed, including the crust, mantle and lunar core, with emphasis on the contribution of higher degree gravity field models to the study of shallow structures. The remaining problems associated with the internal structure’s inversion using lunar gravity data are also analyzed in the paper. Finally, we looked forward to the development of lunar gravity detection techniques and the prospects for future applications of gravity field to study the lunar interior structure.
