- [目的]揭示北部湾城市群人口城镇化和土地城镇化质量时空演变特征,阐明人口-土地城镇化质量耦合协调度及规律,进而为区域城镇化过程人地资源管理与配置提供科学依据。[方法]在分析人口-土地城镇化相互作用关系框架基础上,构建人口城镇化和土地城镇化质量评价指标体系,采用弹性系数法、耦合协调度模型和核密度等方法,定量测度和分析了2005—2019年北部湾城市群人口-土地城镇化质量及耦合协调发展演变特征。[结果]2005—2019年北部湾城市群人口城镇化与土地城镇化质量呈现不断上升的趋势,但总体水平相对不高,且各城市单元之间城镇化质量差异明显。约60%的城市属于土地城镇化质量滞后型,26.67%的城市是人口城镇化质量滞后型,13.33%的城市人口与土地城镇化质量协调同步。北部湾城市群人口-土地城镇化整体耦合协调发展程度不断上升,且空间差异性呈缩小趋势; 空间上表现为海口市耦合协调度较高(优质协调型),南宁和北海两市为良好协调型,其他城市属于轻度或中等协调类型。[结论]北部湾城市群人口城镇化与土地城镇化耦合协调关系空间差异明显、总体趋好,可分为五种类型城市,并针对性地提出差别化的城镇化发展建议。
- Abstract:
- [Objective] Understanding the coupling coordination relationship and spatial differences between population urbanization and land urbanization in the urban agglomerations is not only the key to expedite the rational allocation of human and land resources in urbanization process, but also of great significance to China's new urbanization initiative, which promotes healthy, scientific and sustainable urban transition. [Methods] The Beibu Gulf Urban Agglomeration(BGUA)was taken as a case. Based on the interaction between population urbanization and land urbanization, population urbanization and land urbanization quality evaluation index system was constructed, and the population-land urbanization quality and spatiotemporal characteristics from 2005 to 2019 were measured. Meantime, the coordination relationship between population urbanization and land urbanization was quantitatively analyzed and discussed by using the elastic coefficient, coupling coordination degree model and kernel density estimation method. [Results](1)Although the overall urbanization level of BGUA was relatively low and the quality of urbanization varied significantly among cities, the qualities of population urbanization and land urbanization in the BGUA both showed an increasing trend.(2)Contrast type of population urbanization and land urbanization always appeared to land lag, these cities accounted for 60%. About 26.67% of cities were that population urbanization lagged behind that of land urbanization, while 13.33% of cities were population-land urbanization synchronous type.(3)The overall coupling coordinated degree of population-land urbanization in the BGUA showed a general upward trend, and its spatial differences tended to narrow. In space, the coupling coordination degree of Haikou City was the highest(0.915)and belonged to high-quality coordination type, followed by Nanning and Beihai City with the coupling coordination degrees of 0.796 and 0.744, respectively. The coupling coordination degrees of the other cities were relatively low and experienced a change from mild non coordinated type to slight and medium coordination type. [Conclusion] From 2005 to 2019, the spatial differences in the coupling and coordination relationship between population urbanization and land urbanization in the BGUA showed a clear trend of improvement. From the perspective of promoting the benign and coordinated development of urbanization in various cities, the BGUA was divided into five types based on different levels of urban development and coupling coordination degrees, and the innovatively differentiated population land urbanization development strategies and countermeasures were proposed according to local conditions.
