2009-2018年广西城市化与城市土地集约利用时空耦合协调发展

目的]探讨广西壮族自治区城市化与城市土地集约利用的耦合协调性的时空特征,更好地促进城市化可持续发展进程。方法]采用熵值法评价广西14个地级市2009-2018年城市化与城市土地集约利用之间的耦合协调发展关系,基于耦合模型分析其时空分异格局。结果]①2009-2018年广西各地级市城市化与城市土地集约利用耦合协调发展经历了磨合阶段-颉颃阶段-高水平耦合阶段的演变过程,整体耦合协调性不断优化;②各地级市相对发展度多处于同步状态和滞后状态,地区之间发展不均衡;③耦合协调类型多处于Ⅳ,Ⅴ,Ⅶ和Ⅷ类,整体耦合协调水平良好。结论]①从时间尺度上看,广西各地级市耦合协调水平呈现稳定上升的趋势,由颉颃阶段逐渐转入磨合阶段,相对发展关系趋向于滞后发展。②从空间尺度上看,两者耦合协调发展关系呈现出片状分区集聚的特征,地域分异明显,桂东地区较桂西地区耦合协调水平高,桂中地区稳定发展。各地级市之间应加强协作,高水平协调城市带动低水平耦合发展城市,促进城市化进程可持续化发展。

Coordinated Development of Time and Space Coupling Between Urbanization and Urban Land Intensive Use in Guangxi Zhuang Autonomous Region During 2009-2018

Objective]The temporal and spatial characteristics of the coupling and coordination between urbanization and intensive use of urban land in Guangxi Zhuang Autonomous Region(GZAR)were studied to promote the sustainable development of urbanization.Methods]The entropy method was used to evaluate the coupling and coordinated development relationship between urbanization and urban land intensive use in 14 prefecture-level cities in GZAR from 2009 to 2018.The temporal and spatial differentiation patterns were analyzed based on the coupling model.Results]①From 2009 to 2018,the coordinated development of urbanization and urban land intensive use in GZAR prefecture-level cities experienced the evolution process of the running-in phase,antagonism phase,and high-level coupling phase,and the overall coupling and coordination continued to be optimized.②The degree of coordination was mostly in the state of synchronization and lag,and the development between regions was not balanced.③The types of coupling coordination were mostly in categoriesⅣ,V,Ⅶ,andⅧ,and the overall level of coupling and coordination was good.Conclusions]①From the time scale,the level of coupling and coordination of various cities in GZAR showed a steady upward trend,gradually turning from the antagonism stage to the running-in stage,and the relative development relationship tended to lag behind.②From the spatial scale,the coupled and coordinated development relationship between the two showed the characteristics of flaky zoning and agglomeration,with obvious geographical differentiation.The level of coupling and coordination in the east of GZAR was higher than that in the west,and the central GZAR region was seen to have developed steadily.Local-level cities should strengthen collaboration,coordinate with high-level cities to drive low-level coupled development cities,and promote the sustainable development of urbanization.
