Starting from the analysis of the developing background and situation in various development zones in Tianjin, this paper reviewed the relationship between city and development zone as well as the contribution of development zone to urban development in Tianjin. The development zone construction becomes an important economic growth pole in Tianjin and brings along the urban economic development of the whole city. Based on this fact, the relationship between development zone and urban spatial structure evolvement is clarified. The type of development zone and urban spatial structure evolvement belongs to the double-core one. The rapid economic growth of development zone and construction lead to expansion of urban space in Tianjin. The development zone inf1uences urban spatial structure of Tianjin from two aspects, one is bringing on the increase of urban space, and the other is the change of urban morphology. Using land use vector data of the three periods in the mid -1980s, 1995 and 2000 at a scale of 1:100,000 and the CBERS-02 data in 2007, and taking GIS as an analysis method, the changes by automatic classification and integration by man and machine were interpreted for CBERS-02 data. Then it was overlapped with the former data. So we obtain dynamic changes information of urban expansion throughout the study period. Then the urban land area change and spatial expansion rules are summarized. In the 1990s, various development zones were established at a large scale and industrial space sprawled out-of-order rapidly, making urban space layout change from single-core growth to axes spreading out along the Hahei River. Consequently, the double-center and group urban layout structure comes into being, which is described as one shoulder pole carries two sides, taking central urban area and Binhai new area as head and assistant center as well as a double-core with clear division of industrial and commercial functions.
