Study on regional land use structure is to provide a basis for coordinating the relationship between the quality of regional economic construction and the optimization of land use structure under the background of economic transformation. This paper used information entropy model and SSM model to analyze the difference of spatiotemporal pattern of land use structure in Nanjing City from 2005 to 2016, and build econometric model to discuss its diving factors. The results show that:(1)according to the general dynamic evolution rule of information entropy, information entropy of land use structure in Nanjing City had obvious periodicity and it showed that the period from 2005 to 2009 was a continuous growth period(disordered), the period from 2010 to 2012 was a continuous decline period(orderly), and the period from 2013 to 2016 was a fluctuation uplift period(disordered);(2)the general analysis of information entropy, equilibrium degree and superiority degree showed that the equilibrium degree of land use structure in Nanjing City presented the trend of ‘increase—decrease—increase’ and superiority degree was the opposite, among which the agricultural land structure was the evolution trend of ‘disordered—orderly’, while the construction land structure was the evolution trend of ‘orderly—disorderly’;(3)from the evolution of different geodetic spaces, agricultural land and other land belonged to attenuation structure, among which cultivated land and grassland had a significant crowding-out effect; construction land basically belonged to growth structure, among which land for urban and rural construction and for transportation and water conservancy showed the significant supply effect;(4)the competition of different land use type in ‘four areas’ of Nanjing City showed the significant difference in space configuration, that was the main urban area was in state of ‘middle value zone—low value zone’, Jiangbei New Area and the near suburbs were in state of ‘middle-high value zone—high value zone’, and the far suburbs were in state of high value zone;(5)the evolution of spatiotemporal pattern of land use in Nanjing City was mainly influenced by land resource endowment, economic development level, industrial structure adjustment and land management policies.
