The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), also known as the Guoshoujing Telescope, is a major national scientific facility for astronomical research located in Xinglong, China. Beginning with a pilot survey in 2011, LAMOST has been surveying the night sky for more than 10 years. The LAMOST survey covers various objects in the Universe, from normal stars to peculiar ones, from the Milky Way to other galaxies, and from stellar black holes and their companions to quasars that ignite ancient galaxies. Until the latest data release 8, the LAMOST survey has released spectra for more than 10 million stars, ∼220,000 galaxies, and ∼71,000 quasars. With this largest celestial spectra database ever constructed, LAMOST has helped astronomers to deepen their understanding of the Universe, especially for our Milky Way galaxy and the millions of stars within it. In this article, we briefly review the characteristics, observations, and scientific achievements of LAMOST. In particular, we show how astrophysical knowledge about the Milky Way has been improved by LAMOST data.
大天区面积多目标光纤光谱天文望远镜（LAMOST），又称郭守敬望远镜，是一台位于中国兴隆的用于天文研究的国家重大科学装置。自2011年进行先导巡天以来，LAMOST已经对夜空进行了超过10年的巡天观测。LAMOST巡天涵盖了宇宙中的各种天体，从正常恒星到奇特恒星，从银河系到其他星系，从恒星黑洞及其伴星到点燃古老星系的类星体。截至最新的第8次数据发布，LAMOST巡天已发布了超过1000万颗恒星、约22万个星系和约7.1万个类星体的光谱。凭借这个有史以来构建的最大的天体光谱数据库，LAMOST帮助天文学家加深了对宇宙的理解，特别是对我们的银河系及其内部数以百万计的恒星的理解。在本文中，我们简要回顾了LAMOST的特点、观测和科学成果。特别是，我们展示了LAMOST数据如何增进了对银河系的天体物理学认识。
