Abstract:: Taking the present land use data of Linyi city in 2010 as the main information source, based on the landscape index and GIS spatial analysis method, the general pattern of land use landscape characteristics and spatial distribution rules in Linyi city were analyzed and discussed. The results showed that the dominant pattern of the landscape in Linyi city was farmland, the proportion of its total area nearly accounts for 50 percent of all sub-areas, followed by construction land and forestland. Different landscape types exhibited distinctive spatial signatures along the gradient buffer zones with class-level landscape indices. Analysis of landscape level pattern showed that patch fragmentation gradually increased from the city to suburb, the shapes of landscape became more complicated, landscape tended to be more diverse. The results suggest that combination of landscape metrics and gradient analysis is a robust tool to study the spatial pattern of urbanization.
