Abstract: Urbanization is one of the primary factors that contribute to the variations of regional landscape (e.g. landscape structure and landscape pattern). Landscape ecological analysis of two-phase landscape distribution in Dachangshan Island provided estimates of the local dynamic changes between 1995 and 2006. Simulation of the landscape pattern as well as the relative dynamic mechanism in 2017 was then conducted on the basis of these data through CA-Markov model. The result showed that the landscape pattern in Dachangshan Island modified from natural into artificial between 1995 and 2006 with the process of urbanization, which was characterized by the shrink of the farmlands, grasslands, commercial areas, industrial areas (include mining areas) and the increase of garden lands, water facilities, residential quarters, public service areas, etc. In addition, simulation indicated the changes between 2006 and 2017 was mainly displayed as the decrease of farmlands, grasslands, garden lands in the focus area and the increase of other lands, but neither the increase rate nor the shrink rate plunged in this period.
