- W2357987002 abstract "Urban growth model was the simplification of the urban area, which was expected to present and simulate the dynamic processes of urbanization through the mathematical methods, and provide a very useful analysis tool to understand and capture the characteristics of urban growth. The Logistic-CA model was widely used in the existing researches of the urban growth simulation, while it was difficulty to reflect the nonlinear and dynamic characteristics of the urban growth for its static coefficients. To deal with this deficiency, a variable-coefficient urban growth model was developed through the error feedback control in this artcle. Firstly, four pixel types were generated according to the comparison between the simulation result and real situation, which includes the Omission Error(OE) pixels, Commission Error(CE) pixels, Urban Correct(UC) pixels and Non-urban Correct(NUC) pixels, then the simulation error was mapped into the urban growth model to modify the coefficients through the linear programming method. Finally, the variable-coefficient urban growth model was built based on the error feedback control. To validate the effect of the variable-coefficient model, both the Logistic-CA and variable-coefficient model were used to simulate the urban growth process of Beijing City from the year of 1997 to 2009. The results showed that the accuracies of Logistic-CA model in 2001, 2005 and 2009 were 73.842%, 64.704% and 63.953%, respectively, while these values of the variable-coefficient urban growth model were 75.624%, 66.537% and 69.142%, which were 1.782%, 1.833% and 5.189% greater than the former. It can be demonstrated that the variable-coefficient model could present the real situation of urban growth and obtain a better simulate results. The results of this article had a high theoretical and practical significance, for it could provide a new method and view to guide the research of urban growth simulation, but also provide an ancillary evidence for the urban planning and decision." @default.
