Identifying urban vitality of urban communities in large cities is critical for optimizing the urban form. While great attention has been paid to urban vitality in developed countries, this kind of study has been paid relatively less attention in developing countries like China. This paper focuses on the evaluation of urban vitality at the scale of communities, accompanying the rapid suburbanization of housing. We developed a framework for measuring urban vitality of communities using the dimensions of internal environment, external environment and human activities. We selected the mountainous city of Chongqing and the plain city of Chengdu as case for study. We aimed to assess the spatial variations of urban vitality in communities. We found that great variations of urban vitality exist between the two cities. Due to the dispersed pattern of communities, Chongqing has relatively high urban vitality in the subcenters. Because of pan-like spatial distribution of community pattern, Chengdu has a high concentration of viable area in the central area. From the city core to the periphery, urban vitality in communities is declining in both cities. We also discovered the spatial changes of urban vitality in communities have a great relationship with urban patterns and human activities.
