Abstract:

Improving urban ecological resilience and efficiency, and promoting coordinated development between these two systems are the primary objectives of ecological governance in the Yellow River Basin, China. Considering 57 cities in the Yellow River Basin as the research target, this study analyzed the spatial and temporal evolutionary characteristics of urban ecological resilience and efficiency based on the weighted summation method and the slacks-based measurement (SBM) model for the period from 2009 to 2018. Furthermore, a coupled coordination model was employed to analyze the coordinated development of urban ecological resilience and efficiency in cities along the Yellow River Basin. The study results showed the following: (1) During the study period, the urban ecological resilience of cities along the Yellow River Basin had a fluctuating declining trend overall, and these cities faced greater ecological threats and environmental pressures. Xi’an, Zhengzhou, and Jinan City are three provincial capitals that show high urban ecological resilience, whereas Guyuan, Dingxi, Haidong, and Lüliang City showed low urban ecological resilience. (2) The urban ecological efficiency of cities along the Yellow River Basin was generally characterized by a “U”-shaped evolution; in other words, the efficiency first decreased and subsequently increased. Dingxi, Longnan, Qingyang, Ordos, Guyuan, and Luoyang City showed a high level of urban ecological efficiency, while cities with low urban ecological efficiency were mainly located in Shanxi, Henan, and Shandong provinces in the middle and lower reaches of the Yellow River. (3) The coordination relationship between ecological resilience and efficiency is similar to that of the ecological efficiency subsystem, which changed from a continuous decline to a gradual recovery. During the study period, the number of cities with good and moderate coordination between urban ecological resilience and efficiency increased, while the number of cities with poor coordination decreased. Furthermore, while the coordinated development momentum of ecological resilience and efficiency of cities in the basin is apparent, the contradiction between economic development and environmental protection continues to be prominent in the short term. Thus, results of this study contribute to the knowledge base regarding the formulation of ecological policies, improvement of urban ecological resilience, and promotion of urban ecological efficiency in cities in the Yellow River Basin.
