生态文明背景下健康城市发展与土地集约利用耦合协调关系研究——以京津冀为例

Study on Relationship of Coupling Coordination between the Development of Healthy City and the Intensive Use of Land under the Background of Ecological Civilization:A Case from Beijing-Tianjin-Hebei Region

利用熵值法、耦合协调度模型等研究了生态文明背景下,2007—2017年京津冀13个城市健康城市建设与土地集约利用的发展状态、耦合协调分布特征及其驱动力。结果表明:(1)京津冀健康城市发展与土地集约利用水平均值随时间均以京津为中心向四周扩散递减,但健康城市发展整体水平要优于土地集约利用。(2)耦合协调水平区域差异明显,但随时间差距逐渐缩小;历年耦合协调水平在空间上均呈显著集聚状态,但空间差异逐渐缩小。(3)因子探测器显示第三产业增加值占GDP比重是影响耦合协调发展的主导驱动因子,交互式探测器进一步揭示了各驱动因子的交互促进能力。研究结果对于推进京津冀一体化发展、缩小区域差异具有重要意义。

Based on entropy method,coupling coordination degree model and other methods,the development state,coupling and coordinating distribution characteristics and driving forces of healthy urban development and land intensive use were studied in 13 cities of Beijing,Tianjin and Hebei from 2007 to 2017 under the background of ecological civilization.The results show that:(1)The comprehensive level and average value of healthy urban development and land intensive use in Beijing,Tianjin and Hebei are all centered in Beijing and Tianjin,and gradually spread around,but the development level of healthy city was better than that of land intensive use.(2)There are obvious regional differences in the level of coupling coordination,but the differences gradually narrow with time;the level of coupling coordination is in a state of significant agglomeration in space with time,and the spatial differences gradually reduced.(3)Factor detector shows that the proportion of added value of the tertiary industry in GDP is the main driving factor affecting the coordinated development of coupling,and interactive detector further reveals the interactive promotion ability of each driving factor.The research results are of great significance to promote the integrated development of Beijing,Tianjin and Hebei and reduce regional differences.
