Abstract:: The purpose of this paper is to provide service for land use and ecological environment plan by summarizing changes of categorical distribution in coastal region. The solution is to design methods to analyze the changes of barycenter and gradient in coastal region by using Fragstats software, RS and GIS technology. The results indicate that areas of some lands are reduced, such as cultivated land, grassland, wetland and saline land; the areas of some lands are increased, such as corner, construction land, salt pan and water body. The barycenter of the lands are migrating in different directions. Landscape spatial gradient from the horizontal and vertical transects reflects the characteristics of the coastal region. In horizontal transect, farther from the center of town, the landscape tends to be more complex and diverse, and its aggregation index is worse. In vertical transect, from south to north, Shannon diversity index is upward in the overall trend. In center city, aggregation index is increasing to the south, and it rises slightly at first and then declines to the north.
