摘要：Most cities in China have experienced dramatic changes during the systematic progress of modernization and commercialization. Rebuilding residential space into heritage preservation is popular in Chinese urban planning. Yearning for modernity generates a policy of cultural protection which is transformed by the public spaces within which people carry out daily lives. However, heritage preservation in these cities is in a dilemma. On side, with the opening up, Chinese society toward modernization has been accompanied by large-scale urbanization, rapid commercialization and a booming consumerism. The Chinese capital has forced people to face the challenge of urban environment management and adaptation to a new city. The traditional streets in big cities are destroyed first and then rebuilt to turn the capital into an international metropolis. On the other side, heritage protection needs its historical roots as the authentic cultural features. To some extent, the process of urban landscaping stimulates people＇s nostalgia tie. Although it seems to be individual, it is also a link of one＇s historical memory of sentiment with the development of social construction. Hence, collective urban nostalgia that emerged through the rebuilding of heritage in urban China can promote nationalism from the governmental perspective. Further, it can also lead people face the life itself but neglect the social tensions around them. Meanwhile, rebuilding mode of Longtang also elaborates the power structure existing among state, capital, intellectuals.
