Urbanization is still one of the social themes in developing countries. In China, the rapid process of urbanization and economic growth bring to people not only more opportunities for creating new life and pursuing happiness, but also the challenge to face various and complex social, economical and environmental problems. Among them some are outstanding, like the shrinking plowland devoured by urbanization, the withering of village abandoned by urbanization, the inflating price of house and rent pushed by urbanization, and the severe-completing and fighting for public resources evoked by urbanization. While local dwellers are moving out and the out-comers flooding in, the traditional public context is heavily destroyed, and various environment issues are also emerging. Basing on a survey of Ro. Xihuangcun in Beijing, China, this article has made a near analysis on public space, trying to cast light on a model in urbanization, and to draw some constructive suggestion and solution to this selected area as well.
