| 摘 要： | 为深入探究区域城镇化与生态环境协调发展水平,以长江经济带为例,基于城市土地利用效率与生态系统健康视角构建相关理论框架,综合运用SBM-Undesirable模型、VOR模型及耦合协调度模型测算长江经济带城市土地利用效率与生态系统健康,分析两者的耦合协调特征并识别了其协调发展问题区域。结果表明:(1)2005—2018年长江经济带城市土地利用效率年均值达0.746,整体上呈波动式缓慢上升的趋势,空间集聚特征较为显著。生态系统健康得分均值为0.473,整体呈现小幅波动的趋势,地理空间上则呈现显著的南北分异特征;(2)城市土地利用效率与生态系统健康耦合协调度均值在0.611～0.624区间内小幅增长,截至2018年,区域内实现协调发展的市域达92.62%,耦合结果在空间上表现为由“相对随机”向“南高北低”的分布转变;(3)城市土地利用效率与生态系统健康耦合协调问题区域主要存在于长江经济带中下游部分市域,主要原因在于城市土地利用效率或生态系统健康单方面滞后抑制了城市协调发展水平的提升。总体而言,长江经济带城市土地利用与生态系统之间相互影响、相互促进的程度正逐步深化,交互过程中形成的耦合系统基本实现了平稳发展。

| Abstract: | In order to explore the coordinated development level of regional urbanisation and ecological environment, taking the Yangtze River Economic Belt as an example, constructing a related theoretical framework based on the perspective of urban land use efficiency and ecosystem health, and comprehensively using the SBM-Undesirable model, the VOR model and the coupling coordination degree model to calculate urban land use efficiency and ecosystem health in the Yangtze River Economic Belt, the coupling and coordination characteristics of the two was analysed, and problem areas of coordinated development were identified. The results show that:(1)The annual average value of urban land use efficiency in the Yangtze River Economic Zone is 0.746 from 2005 to 2018, and the overall trend is slow and fluctuating, with significant spatial agglomeration characteristics. The average value of ecosystem health score is 0.473, showing a slight fluctuation trend as a whole, and showing significant north-south differentiation in geographical space;(2)The mean value of urban land use efficiency and ecosystem health coupling coordination degree increased slightly in the interval of 0.611 to 0.624. As of 2018, 92.62% of the cities in the region have achieved coordinated development, and the results of the coupling are spatially transformed from ‘relatively random' to ‘high in the south and low in the north';(3)Urban land use efficiency and ecosystem health coupling coordination problem areas mainly exist in some cities in the central and lower reaches of the Yangtze River Economic Belt. The main reason is that urban land use efficiency or ecological system health is unilaterally lagging, which inhibits the improvement of the level of urban coordinated development. In general, the degree of mutual influence and promotion between urban land use and ecosystems in the Yangtze River Economic Belt is gradually deepening, and the coupling system formed in the interaction process has basically achieved stable development. |
