In 2013, the goal of constructing "beautiful countryside" was put forward for the first time in China. People are increasingly aware of the importance of rural construction for the development of Chinese society, and rural civilization urgently needs to be revived. Under the background of the national rural revitalization strategy, the construction of "beautiful countryside" is in full swing, setting off another upsurge of rural construction in China. As a common form of art expression in public space, public art integrates into rural revitalization with a more active attitude, trying to awaken and activate rural culture, build a harmonious symbiosis between man and nature, promote comprehensive improvement of rural strength, and bring happiness to villagers. However, subject to factors such as regional characteristics, historical context, national culture, folk traditions, and economic development level, homogeneity, superficiality and many potential problems have become obstacles to the process of public art intervention in the construction of "beautiful countryside". Those unavoidable contradictions make it difficult to form a sustainable development situation. This work starts with domestic and foreign rural public art creation cases, conducts an in-depth analysis on the characteristics of rural construction public art, the reasons for intervention, intervention methods, content, and value significance of rural construction public art, and systematically summarizes the main problems encountered by public art intervention in rural construction. Targeted solutions to those problems are also discussed in this paper to inject stronger cultural vitality into the construction of "beautiful countryside" through public art intervention, awaken civilization awareness of villagers and culture self-consciousness of the countryside, and make "beautiful countryside" truly come true.
