Abstract: The temporal and spatial change of landscape pattern in Qinhuangdao city since the early 1990s was analyzed based on RS and GIS survey. The land use information was acquired by interpreting the TM image data of 1993, 2000 and 2008, and 6 landscape indices (the proportion of all patches (PP), average patch area (APA), average patch perimeter (APP), average perimeter-area ration (APAR), fractal dimension (FD) and aggregation index (AI)) were adopted to characterize the spatial pattern of landscape during these three periods. The transition matrix was used to analyze the varying characteristics of all landscape types. The result showed that, natural and semi-natural landscape types, such as forest, grass and water body, decreased, so did agriculture land, however, the dry-land increased because of the decreasing irrigated land. The increased land for construction because of the human's activities, such as construction of cities and roads, is shown to be the main driving force for the changing landscape pattern.
