广西钦州市土地利用效益与城市化耦合协调度研究

Evaluation on the Coupling and Coordination Development between Land Use Benefits and Urbanization in Qinzhou,Guangxi

以钦州市为研究对象,通过构建反应土地利用效益与城市化耦合协调度的指标体系,利用耦合度模型和协调度模型探讨两者间的关系。研究结果表明:2003—2012年钦州市土地利用效益综合指数在微量波动中稳定上升,城市化综合指数呈快速上升的趋势。钦州市土地利用效益与城市化耦合作用强度进入了颉颃阶段,耦合度值差异相对不大。土地利用效益与城市化协调度经历了低度协调耦合、中度协调耦合、高度协调耦合三个阶段。

Taking Qinzhou as study subject ,this paper constructed an index system on the cou‐pling land use benefits and urbanization and used the coupling model and coordination model to ex‐plore the relationship between them .The results show that :the composite index of land use benefits rose steadily in the micro wave ,however ,the urbanization comprehensive index increased rapidly dur‐ing 2003-2012 .The coupling intensity of land use benefits and urbanization of Qinzhou has come into middle stage .The coupling value differences have been relatively modest .The coupling coordination degree of land use benefits and urbanization experienced low‐grade coordination level ,moderate level and high coordination level .
