摘要

[目的] 探明城市紧凑度与土地利用效益的交互关系，为促进地区新型城市化和高质量可持续发展提供依据。[方法] 在推演城市紧凑度与土地利用效益耦合机制的基础上建立指标体系，以广西壮族自治区为例，运用加权求和法、耦合协调度模型分析2003—2018年二者关系的时空特征。[结果] ①2003—2018年广西城市紧凑度呈波动上升趋势，紧凑度指数由0.301升至0.433，高紧凑度城市主要在桂中和桂北，低紧凑度城市集中于桂西北和桂东南两侧，中紧凑度城市环高紧凑度城市分布；②广西城市土地利用效益经历了“稳步优化—加速增长”的梯度提升过程，评分由0.363跃至0.574，土地利用效益呈现“南北高—东西低”的空间格局；③广西城市紧凑度与土地利用效益耦合协调度由0.408低速升至0.504，协调类型从勉强协调向初级协调过渡，各市经历了“濒临失调—勉强协调—初级协调”的演变过程，协调类型总体上呈现“点面—簇团—线性带状”的格局演变。[结论] 广西城市紧凑度与土地利用效益的相互促进作用偏弱、协调关系不紧密，促进二者协调发展对解决城市化过程中所产生的负面问题具有重要作用。

Abstract

[Objective] The interactive relationship between urban compactness and land use efficiency was explored

in order to provide a basis for promoting new urbanization and high-quality sustainable development in the region. [Methods] The index system was established based on the model of coupling urban compactness and land use efficiency

and the spatial and temporal characteristics of the relationship between them in Guangxi Zhuang Autonomous Region from 2003 to 2018 were analyzed by using the weighted summation method and the coupling coordination degree model. [Results] ① The urban compactness of Guangxi Zhuang Autonomous Region from 2003 to 2018 showed a fluctuated upward trend

and the compactness index increased from 0.301 to 0.433. The high compactness cities were mainly distributed in central and Northern Guangxi

the cities of low compactness were concentrated in Northwest Guangxi and Southeast Guangxi on both sides

and the cities of medium compactness were ringed around the cities of high compactness. ② The land use efficiency of cities in Guangxi had experienced the gradient improvement process of “steady optimization-accelerated growth”

and the scores had risen from 0.363 to 0.574. The land use efficiency showed the spatial pattern of high in the north and south

and low in the east and west. ③ The coordination degree of coupling between urban compactness and land use efficiency in Guangxi area increased from 0.408 to 0.504 at a low speed

the coordination type transitions from barely coordinated to primary coordination. Each city experienced the evolution process of “on the verge of disorder—barely coordinated—primary coordination”. In general

the coordination type showed the pattern of “point surface—cluster—linear belt”. [Conclusion] The mutual promotion role of urban compactness and land use efficiency in Guangxi area is weak

and their coordination relationship is not close. Promoting the coordinated development of them plays an important role in solving the negative problems in the process of urbanization.
