摘　　要：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 andone of the most active frontiers in the field of astrophysics, among which is the chemical evolutionof the Galaxy showing its exceeding importance. With ever-growing and better observationaldata being available and theoretical research work vigorously developing, there have been a seriesof progress in the study of the chemical evolution of the Galaxy. The present paper gives abrief introduction of the development in observational constraints and theoretical models in thisfield. In the observational aspect, recent results of the main observational constraints on Galacticchemical evolution models are briefly reviewed, including those for the solar neighbourhood, theGalactic disk, halo and bulge. As for the evolution model, it looks back on the history of thedevelopment of the studies, and on recent progress. It also looks forward to further researches inthis area.
