    摘要:

    [目的] 探究甘肃省庆阳市土地集约利用与土地利用结构之间的协调关系,为该市土地利用结构优化和社会经济的可持续发展提供理论依据。[方法] 以庆阳市为例,采用多因素综合评价法计算2007—2016年土地集约利用、土地利用结构的综合指数,应用耦合协调模型,分析二者变化特征及耦合协调关系。[结果] ①庆阳市土地集约利用综合指数呈上升趋势,达到了高度集约利用水平。②庆阳市土地利用结构信息熵总体呈下降趋势,均衡度逐渐降低,优势度逐渐增强。③土地集约利用与土地利用结构耦合度呈先上升后下降的趋势,耦合协调度都呈上升趋势,二者耦合性越来越强,相对呈现出协调、稳定的发展趋势。[结论] 2007—2016年庆阳市土地集约水平总体变化呈逐年上升状态,但信息熵呈下降趋势,是由于大力开发未利用地,植树造林使得土地利用结构调整。土地集约利用和土地利用结构两系统协调度都呈上升趋势,二者耦合性越来越强。说明庆阳市在大力推动经济发展的同时,也注重提高土地利用的效率,调整土地利用结构,优化布局。

    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and land use structure, it is found that the unit input to promote the level of land intensive use in Qingyang City is no longer applicable, and the land use structure need to be changed in order to further improve the efficiency of land use and promote the level of land intensive use.
