Every day, our living city produces a tremendous amount of spatial-temporal data, involved with multiple sources from the individual scale to scale. Undoubtedly, such massive urban data can be explored for better and life, as what computing community has been dedicating in recent years. Nevertheless, existing studies are still facing challenges fusion well knowledge distillation specific applications. Moreover, there is lack full-featured user-friendly platforms both researchers developers scenario. Therefore, this article, we present UrbanKG, an graph system incorporate computing. Specifically, introduces complete scheme construct fusion. Built upon layer, further develops layers construction, storage, algorithm, operation, applications, which achieve support various functions users. We perform representative use cases demonstrate capability boosting performance downstream indicating promising research direction knowledge-driven
