银河系的形成与演化是天体物理学研究的重大前沿课题，银河系的化学演化 在其中更具有极其重要的地位。随着观测资料的不断积累和理论工作的不 断深入，银河系化学演化的研究取得了一系列进展。在观测方面，从太 阳附近区域、整个银盘、银晕和核球等方面简要回顾了银河系化学演化模型 主要观测约束的近期结果；在化学演化模型方面，回顾了银河系化学演化研 究的发展历程和近期进展，并对未来的研究进行了展望。

The formation and evolution of the Galaxy has long been a basic and important branch and one of the most active frontiers in the field of astrophysics, among which is the chemical evolution of the Galaxy showing its exceeding importance. With ever-growing and better observational data being available and theoretical research work vigorously developing, there have been a series of progress in the study of the chemical evolution of the Galaxy. The present paper gives a brief introduction of the development in observational constraints and theoretical models in this field. In the observational aspect, recent results of the main observational constraints on Galactic chemical evolution models are briefly reviewed, including those for the solar neighbourhood, the Galactic disk, halo and bulge. As for the evolution model, it looks back on the history of the development of the studies, and on recent progress. It also looks forward to further researches in this area.
