摘 要:科学测度黄河流域城市群城市生态韧性的发展现状及收敛趋势,对于黄河流域城市生态保护及高质量发展具有重要意义。选取2011—2020年黄河流域七大城市群61个地级市面板数据,以演化韧性为研究视角,从“抵抗-响应-创新”等维度,构建城市生态韧性评价指标体系,利用核密度估计和自然断裂法考察城市生态韧性的空间分异,借助不同类型收敛模型解析城市生态韧性的收敛趋势。研究表明:(1)黄河流域城市生态韧性总体均值为0.093,且呈缓慢发展趋势。(2)城市生态韧性表现为“下游城市群强、上中游城市群弱”的空间格局,城市群内部形成了“核心及省会城市—外围及边缘城市”递减的空间分布。(3)黄河流域和各城市群内部均存在绝对β收敛,其中晋中城市群收敛最快。加入控制变量后,黄河流域和各城市群内部呈现显著条件β收敛趋势,且收敛速度均有提升。此外,经济发展水平、人口密度等变量对城市生态韧性收敛的影响具有显著异质性。The scientific measurement of the development status and convergence trend of urban ecological resilience in the Yellow River Basin urban agglomeration is of great significance for the ecological protection and high-quality development of Yellow River Basin.This study selects the panel data of 61 prefecture-level cities in the seven major urban agglomerations in the Yellow River Basin from 2011 to 2020,takes evolutionary resilience as the research perspective,constructs an urban ecological resilience evaluation index system from the dimensions of resistance-response-innovation,examines the spatial differentiation of urban ecological resilience using kernel density estimation and the natural break method,and analyzes the urban ecological resilience using different types of convergence models.This study shows the following:(1)The overall mean value of urban ecological resilience in the Yellow River Basin is 0.093,and the trend is slow.(2)The urban ecological resilience exhibits a spatial pattern of“strong downstream city clusters and weak upstream and midstream city clusters”,and a decreasing spatial distribution of“core and provincial capital cities-peripheral and marginal cities”within the city clusters.(3)Absoluteβconvergence exists in the Yellow River Basin and city clusters,among which the Jinzhong City cluster converges the fastest.After adding control variables,the Yellow River Basin and city clusters exhibit a significant conditionalβconvergence trend,and the speed of convergence increases.In addition,the effects of economic development level,population density,and other variables on the convergence of urban ecological resilience are significantly heterogeneous.
