Study on Land Use Structure Based on Information Entropy and GM Prediction in Xuzhou City

Based on entropy theory, the variation of land use structure information entropy, equilibrium degree and dominance degree in Xuzhou City was studied during 2005 and 2009. The land use types that affect the values of information entropy were preliminarily discussed. The information entropy, equilibrium degree and dominance degree were predicted during 2010 and 2015 using the GM (1, 1) model of grey system theory. The results showed that information entropy is an increasing trend year by year. The land use structure in Xuzhou City gradually developed from order to a relatively disordered state. The equilibrium degree increased every year and dominance degree was decreasing year by year, which showed that land use structure in Xuzhou City was evolving to equilibrium.
