Based on the trend analysis of the aging population of China and the aging characteristic in Guangzhou City, this research brings up the concept of the urban aging community, characteristic and targets of it as well. The research has also analyzed the forming and evolving process of aging community in Guangzhou, the spatial characteristics of it, the forming and evolving mechanism of Guangzhou ageing community, the effects of the forming of urban ageing community on the urban functional structure, and the effects on the sustainable development.
