Abstract: Coastal zone’s landscape dynamics is recognized as one of the important aspects of integrated coastal management. In this paper, the land use datasets derived from time series aerial images were employed to study the coastal landscape dynamics of Shanghai from 1994 to 2005, the period of rapid urbanization. During this period, human disturbances caused landscape fragmentation and isolation, and increased landscape diversity. The area of main landscape (agricultural land) continued to decrease, its dominance declined, and became more fragmentation; while the areas of artificial landscapes reflecting urbanization (e.g., lands for industry, traffic, public facility, and residence) increased, becoming the second dominant landscape type. The increasing area of other land uses (mainly constructing sites) implied that this coastal zone was still undergoing rapid urbanization. Central government policies, local government decision-making, rapid urbanization of Shanghai, and coastal big-scale development programs such as Pudong International Airport, Yangshan International Harbor, and Shanghai Chemical Industry Park were the main driving forces for these coastal landscape changes. Based on the analysis of the ecological consequences of this rapid urbanization, some suggestions for integrated management were made to promote the sustainable development of Shanghai coastal zone.
