    摘要:

    [目的] 分析河南省城市韧性与土地利用效率的耦合协调关系,为提高区域安全系数,实现可持续发展提供科学支撑。[方法] 分别构建城市韧性与土地利用效率两系统的综合评价指标体系,采用熵值法、自然断裂点法、数据包络分析(CCR,BCC、超效率DEA模型)及耦合协调度模型测度河南省2019年城市韧性、土地利用效率及两者的耦合协调度,并进行空间类型划分。[结果] ①2019年河南省18座城市的综合韧性在数值和空间分布上均存在明显差异,且经济韧性与生态韧性成负相关关系; ②河南省城市土地利用水平整体呈良好状态,但城市间差距较大; ③河南省城市韧性与城市土地利用效率整体上耦合度较高,耦合协调度低于耦合度。其中17座城市处于城市韧性与城市土地利用效率高水平耦合阶段,仅1座城市为低水平耦合。在空间上,协调城市成“t”型分布; ④依据耦合协调度和相对发展度,可将河南省18座城市划分为7种类型,即高级协调、基本失调、基本协调—城市韧性滞后、基本失调—土地利用效率滞后、基本失调—土地利用效率滞后、基本失调—城市韧性滞后、严重失调—土地利用效率滞后。[结论] 城市韧性系统与土地系统密切相关。未来应将城市韧性建设与提升土地利用效率作为两个抓手,因地制宜地采取措施促进二者协调发展,以实现城市安全、可持续的发展目标。

    Abstract:

    [Objective] The coupling and coordination relationship between urban resilience and land use efficiency in He’nan Province was studied to provide scientific support for increasing the regional security coefficient and realizing sustainable development. [Methods] A comprehensive evaluation index system based on urban resilience and land use efficiency was established, using the entropy method, the natural fracture point method, data envelopment analysis (CCR, BCC, super efficiency DEA model), and the coupling coordination degree model to measure urban resilience, land use efficiency, and the coupling coordination degree of these two quantities in 2019 in He’nan Province. The division of spatial types was also determined. [Results] ① The comprehensive resilience of 18 cities in Hen’an Province showed significant differences in both absolute values and spatial distribution. There was a negative correlation between economic resilience and ecological resilience; ② The overall level of urban land use in He’nan Province was at a good level, but there was a big gap between cities; ③ The coupling degree between urban resilience and urban land use efficiency in He’nan Province was relatively high on the whole, but the coupling coordination degree was lower than the coupling degree. Among them, 17 cities were in the stage of high-level coupling between urban resilience and urban land use efficiency, and only one city was in the low level coupling stage. Spatially, the coordinated cities were distributed in a “t” shape; ④ According to the coupling coordination degree and relative development degree, the 18 cities in He’nan Province could be divided into seven types: high coordination, basic imbalance, basic coordination—urban resilience lag, basic imbalance—land use efficiency lag, basic coordination—land use efficiency lag, basic imbanlance—urban resilience lag, serious imbalance—land use efficiency lag. [Conclusion] The urban resilience system is closely related to the land system. In the future, the construction of urban resilience and the improvement of land use efficiency should be taken as two starting points. Measures should be taken according to local conditions to promote the coordinated development of these two systems so as to achieve the goal of safe and sustainable urban development.
