摘要:  新型城镇化进程在促进社会经济快速发展的同时也导致水环境问题日益严峻。以长江经济带11个省份(直辖市)为研究对象,采用熵值法与耦合协调度模型测算新型城镇化与水环境的耦合协调度,并借助空间自相关模型与灰色关联度模型探讨二者耦合协调度的时空演化及驱动因素。结果显示:(1) 2009~2020年,长江经济带水环境综合水平指数保持平稳,新型城镇化与二者间的耦合协调度整体发展趋势尚好,从空间演变来看,耦合协调度呈现“下游>中游>上游”的分布格局,且区域间差异有所缓和,但整体增长速率较为缓慢。(2)二者的耦合协调度具有显著的正向空间自相关性,且局部的空间自相关表现为聚集趋同特征,空间关联性较强。(3)影响二者耦合协调度的因素按作用强度从大到小依次为产业结构、人口聚集、技术创新、经济驱动和政府能力,且各因素对耦合协调度的作用程度具有明显的地区差异。因此,需充分发挥长江上中下游区域资源优势,推动新型城镇化与水环境协调发展。

Abstract: The process of new urbanization not only promotes rapid socio-economic development, but also leads to increasingly severe water environment problems. This study took 11 provinces (municipalities directly under the central government) in the Yangtze River Economic Belt (YREB) as the research objects, and adopted entropy method and coupling coordination degree model to measure the coupling coordination degree of new urbanization and water environment. Spatial autocorrelation model and grey correlation degree model were used to explore the spatio-temporal evolution and the driving factors. The results showed that: (1) From 2009 to 2020, the comprehensive level index of water environment in the YREB remained stable, and the overall development trend of new urbanization and the coupling coordination of new urbanization and water environment was good. From the perspective of spatial evolution, the coupling coordination degree showed a pattern of "downstream>midstream>upstream". The regional differences slowed down, and the overall growth rate was relatively slow. (2) The coupling coordination of new urbanization and water environment had a significant positive spatial autocorrelation, and the local spatial autocorrelation exhibited clustering convergence characteristic, with a strong spatial correlation. (3) The factors that affected the coupling coordination of new urbanization and water environment in descending order of intensity were: industrial structure, population aggregation, technological innovation, economic drive, and government capacity. The degree of influence of each factor on the coupling coordination degree had significant regional differences. Therefore, it is necessary to pay full attentions to the regional resource advantages of the upper, middle and lower reaches of the Yangtze River, to promote the coordinated development of new urbanization and water environment.
