Based on the detailed survey data of landuse change from 1996to 2008in Zhangjiakou City

many models and methods including the contribution rate of landuse change

dynamic degree of landuse change

information entropy

equilibrium degree

degree of dominance

diversification and centrality degree were used to analyze the landuse structure characteristics and its dynamic change.Results show that:(1)The main landuse types in Zhangjiakou City were arable land

forestland

grassland and unutilized land

which accounted for about 92% of the total land area.(2)The landuse change was obvious in the city from 1996to 2008.The areas of arable land

unutilized land and water body had a drastic reduction

while the areas of forestland

orchard

grassland

construction land and traffic land increased.In terms of the maximum dynamic degree of landuse change

the landuse types from high to low were in the order of forestland

arable land

orchard

unutilized land

traffic land

grassland

construction land and water body.(3)The informationentropy

equilibrium degree of land use for Zhangjiakou City increased

while the degree of dominance decreased

which indicated that land use structure was changing to be disordered and equalization.(4)The centrality degree of landuse increased along with the diversification decreased

which shows that the landuse structure of Zhangjiakou City tended to be diversified.
