    Abstract:

    [Objective] The coordination relationship between intensive land utilization and land use structure was explored in order to provide theoretical basis for the optimization of land use structure and sustainable development of social economy in Qingyang City, Gansu Province.[Methods] Taking Qingyang City as an example, the comprehensive index of intensive land utilization and land use structure from 2007 to 2016 was calculated by multi-factor comprehensive evaluation method. The coupling coordination model was used to analyze the change characteristics and coupling coordination relationship between land intensive utilization and land use structure.[Results] ① The comprehensive index of land intensive utilization showed an increase trend, and reached a high level of intensive utilization in Qingyang City. ② The information entropy of land use structure showed a downward trend, the equilibrium was gradually decreasing, and the advantage was gradually increasing in Qingyang City. ③ The coupling degree of land intensive utilization and land use structure increased initially and then decreased, and the coupling coordination showed an increasing trend. The coupling between the two was becoming stronger and stronger, and showed a coordinated and stable trend.[Conclusion] By studying the relationship between land intensive utilization and land use structure, it is found that the unit input to promote the level of land intensive use in Qingyang City is no longer applicable, and the land use structure need to be changed in order to further improve the efficiency of land use and promote the level of land intensive use.
