Research on Temporal-spatial Land Use Structure Change Based on Information Entropy and Gray Correlative Degree Analysis

WEN Bo et al(College of Public Management,Nanjing Agriculture University,Nanjing,Jiangsu 210095)  
Taking Quannan County of Jiangxi Province as an example,the dynamic changes of land use from 1997 to 2005 was studied as well as the spatial diversity of all villages and towns in 2005 using the information entropy of land-use structure,and the driving forces of information entropy changes was qualitatively researched using the gray correlative degree analysis.The results showed that the information entropy was in a state of sustaining growth during 1997 to 2001,and the equilibrium degree of land-use structure was in a state of sustaining growth as well.But information entropy was in a state of sustaining descend during 2001 to 2005.The diversity was quite large on the information entropy in villages and towns.The factor of population mobility is the most obvious driving forces of the information entropy changes.
