生成式人工智能因操作简便、反馈精准和交互性强等特点，在教育领域引起广泛关注。本文以“南雄珠玑古巷的人口迁移”项目为例，运用“双主体三环节”框架，分析生成式人工智能助教助学的应用价值，构建生成式人工智能赋能高中地理项目式学习的实践路径，反思总结生成式人工智能赋能项目式学习的应用优势与不足。本文旨在为生成式人工智能与项目式学习深度融合提供可操作模式。

Generative artifi cial intelligence (GAI) has garnered widespread attention in the fi eld of education due to its userfriendly operation, precise feedback, and strong interactivity. Taking the project "Population Migration in Zhuji Ancient Alley in Nanxiong" as an example, this paper employs the "dual-subject three-stage" framework to analyze the application value of GAI in assisting teaching and learning. It constructs a practical pathway for GAI to empower project-based learning in high school geography, while refl ecting on and summarizing the advantages and limitations of GAI in enhancing project-based learning. The aim is to provide an operational model for the deep integration of GAI and project-based learning.
