英文摘要：

Communities are important components of urban lives. They are the major carriers of urban habitats, urban culture, and urban human ecology. During China＇s fast process of urbanization, traditional urban communities have been seriously affected. Completely new and vibrant communities have yet to take shape. The advocate by the central government for improving social management ability with scientific methods gave China＇s urban managers a new challenge-paying more close attention to urban community building and development. This paper reviews definitions of community development, discusses how traditional communities have been negatively affected, and proposes that in the process of urban governance innovations, urgent attention is needed for urban community building and development. This would be a foundation work for the building of a harmonious society with scientific methods.
