- [目的]探索长三角城市群2010—2020年的城市韧性和城市土地利用效益的时空演变特征、耦合协调程度及相对发展状况,为推动长三角城市群的协调可持续发展提供参考借鉴。[方法]以长三角城市群26个城市为研究对象,基于熵值法、耦合协调度模型及相对发展度模型,通过构建综合评价指标体系,对长三角城市群城市韧性和城市土地利用效益的耦合协调关系展开了相关研究。[结果](1)研究时间段内,长三角城市群城市韧性总体呈上升趋势,其中超过80%的城市其韧性水平出现上升; 城市土地利用效益呈波动变化趋势。二者皆呈现出“东中部高、南北边缘低”的空间分布格局,且城市韧性由相对零散分布向集聚分布转变,城市土地利用效益由“7”字形分布向“大”字形分布转变;(2)二者的耦合度总体较高,以高水平耦合为主; 协调程度总体较低,但呈现出上升的发展趋势和“东高西低、中心高外围低”的空间分布格局;(3)近1/2城市的城市韧性和城市土地利用效益实现了同步发展,其余城市在2010—2015年多以超前型(城市韧性超前于城市土地利用效益)为主,2015—2020年多以滞后型(城市韧性滞后于城市土地利用效益)为主。[结论]长三角城市群城市韧性和城市土地利用效益的耦合协调度水平较低、发展不平衡,二者没有实现同步发展,未来应加强城市产业结构及土地利用布局的调控和引导,促进城市经济及土地利用的区域协调,统筹城市韧性与城市土地利用协调发展。
- Abstract:
- [Objective] The aim of this study is to explore the spatial and temporal evolution characteristics, coupling coordination degree and relative development of urban resilience and urban land use efficiency of the Yangtze River Delta urban agglomeration from 2010 to 2020, and to provide reference for promoting the coordinated and sustainable development of the Yangtze River Delta urban agglomeration. [Methods] Taking 26 cities of the Yangtze River Delta urban agglomeration as the research object, based on the entropy method, the coupling coordination degree model and the relative development degree model, the coupling coordination relationship between urban resilience and urban land use efficiency of the Yangtze River Delta urban agglomeration was studied by constructing a comprehensive evaluation index system. [Results](1)During the study period, the urban resilience of urban agglomeration of the Yangtze River Delta showed an overall upward trend, with more than 80% of the cities' resilience levels rising, The urban land use efficiency showed a fluctuating trend. Both of them presented a spatial distribution pattern of ‘high in the east and middle, low in the south and north margins', and the urban toughness changed from relatively scattered distribution to the concentrated distribution, and the urban land use efficiency changed from ‘7' to ‘large' distribution.(2)The degree of coupling between the two was relatively high, mainly at a high level. The overall coordination degree was low, but it showed an upward trend of development and a spatial distribution pattern of ‘high in the east and low in the west, high in the center and low in the periphery'.(3)The urban resilience and urban land use efficiency of nearly 1/2 of the cities had achieved synchronous development. The rest of the cities were mainly advanced(urban resilience was ahead of urban land use efficiency)from 2010 to 2015, and mainly lagged(urban resilience lags behind urban land use efficiency)from 2015 to 2020. [Conclusion] The coupling and coordination level of urban resilience and urban land use efficiency in urban agglomeration of the Yangtze River Delta was low, and the development was unbalanced. The two had not achieved synchronous development. In the future, we should strengthen the regulation and guidance of urban industrial structure and land use layout, promote the regional coordination of urban economy and land use, and coordinate the coordinated development of urban resilience and urban land use.
