中国省会城市紧凑度与城镇化水平关系

紧凑型城市建设作为新时期有效避免城市无序蔓延发展、提升城市发展质量和实现土地资源高效利用的新途径,探明城市紧凑度与城镇化的关系对实现城市可持续发展至关重要。基于此,以中国30个省会城市和直辖市为研究对象,综合运用熵值法和容量耦合系数模型测度省会城市紧凑度和城镇化的综合水平,并分析了二者的耦合协调关系。结果发现:（1）2006-2016年间中国省会城市紧凑度东、中、西部地区依次递减,东部省会城市水平最高,整体紧凑度随时间呈增长趋势;（2）高低紧凑度城市逐渐减少,中低紧凑度城市逐渐成为主体;（3）我国大多数省会城市紧凑度与城镇化关系整体以濒临协调为主,总体由失调状态向协调状态演变。

The relationship between urban compactness and urbanization level in capital cities of China

The compact urban construction is a new way to avoid the disorderly spread of the city, improve the quality of urban development and realize the efficient use of land resources. Therefore, it is essential to coordinate the relationship between urban compactness and urbanization level. Based on this, this paper takes 30 provincial capital cities and municipalities directly under the Central Government as the research object, and comprehensively uses the entropy method and capacity coupling coefficient model to measure the comprehensive level of provincial capital compactness and urbanization, and analyzes the coupling and coordination relationship between them. The results show that: (1) The compactness of China's provincial capitals continued to increase between 2006 and 2016. The compactness of the eastern provincial capitals was slightly higher than that of the central and western cities, showing the characteristics of the current situation of the east, the middle, and the west. (2) The city of compactness is gradually decreasing, and the number of the cities with medium and low compactness is increasing. (3) The relationship between compactness and urbanization of most provincial capital cities in China is mainly on the verge of coordination, and the overall transition changes from disordered state to coordinated state.
