“Based on the information of land-uses which was achieved by the satellite remote sensing TM image in 1990 and 2006, this paper took the main urban area of Guangzhou as a study area to analyze its structure and dynamics of land-use changes, as well as the spatial variation of the land-use by dynamic degree of land-use, land-use composite index, and the compactedness coefficient and relative entropy in line with the land-use structure features. The results showed that land-use composite indexes of the main urban area in Guangzhou were in an increased trend, particularly in construction land-use. A large number of farmland, woodland, gardens and waters turned into construction land-uses, so construction land-use areas made a significant growth; trends of regional construction land-use and urban development were scattered; old area’s development and utilization was the most compact form, followed by Huadu, and Panyu and Nansha area were minimum, where is the least relatively compact; entropies of the three regions were higher, which showed that land use and development were in a more scattering and average situation, among the three, entropies of Panyu and Nansha area growing fastest; it also showed that land development and utilization of this area would have a dispersive trend.”
