title: [Simulation of urban expansion based on SLEUTH model in Fuxin City, Northeast China].
abstract: Urban expansion was simulated by SLEUTH model based on the data of Fuxin City, Northeast China in 1997-2013. The optimal parameters of urban expansion were obtained from SLEUTH model calibration, with the diffusion coefficient as 6, breed coefficient as 64, spread coefficient as 44, slope resistance as 52 and road gravity as 90. Urban growth types in Fuxin mainly belonged to new center growth and edge growth, i.e., the further expansion of new and old urban centers. Urban expansion was greatly influenced by roads. Fuxin, as a resource-exhausted city, suffered from the natural disasters, such as landslides, subsidence, and so on. The slope resistance of urban expansion was large in the development of urban land. From the perspective of urban scale, road gravity in smaller city was greater than in larger city. The urban expansion in smaller city was more inclined to the new center growth. The locations of enterprises and new development zones were more interested in the area of good transport facilities. Meanwhile, they were inclined to new center growth. Urban expansions were simulated based on optimal parameters of SLEUTH model. The simulated result of edge growth was better than the simulated result of new spreading center growth, because new spreading center growth was susceptible to policymaking, and cellular influence was little. The simulated accuracy of urban land in 2001, 2006, 2010 and 2013 was high.
