Spatiotemporal evolution characteristics and influencing factors of urban ecological resilience in the Yellow River Basin

中文摘要英文摘要

科学评估黄河流域城市生态韧性对于塑造流域高质量发展优势与营造韧性宜居环境至关重要.基于"压力-状态-响应-创新"四维框架构建城市生态韧性评价体系,运用核密度估计、Da-gum基尼系数等方法考察2011-2020年黄河流域城市生态韧性时序演进、空间分布及空间差异特征,并使用空间杜宾模型剖析其影响因素.结果表明:(1)黄河流域城市生态韧性有效提升,上中下游各地区演进过程、极化特征不尽相同.(2)城市生态韧性空间格局呈"下游-中游-上游"梯度递减,空间集聚与区域分异特征明显.(3)城市生态韧性总体及区域内差异波动式下降,区域间差异是空间差异主要来源,年均贡献率高达65.44%.(4)降水量、经济发展水平、公共安全建设对黄河流域城市生态韧性提升具有正向影响,对外开放水平存在正向溢出效应,基础设施建设、政府干预程度在提升当地城市生态韧性过程中也呈现出正向溢出效应,而土地开发强度、环境污染程度会抑制城市生态韧性提升,且环境污染程度还存在负向溢出效应.此外,黄河上中下游各地区影响因素效果差异显著.

A scientific assessment of urban ecological resilience in China's Yellow River Basin is crucial for shaping the basin's high-quality development advantages and creating a resilient and livable environment.Based on the four-dimensional framework of"Pressure-State-Response-Innovation",this study constructs an urban eco-logical resilience evaluation system and investigates the temporal evolution,spatial distribution,and spatial differ-ence characteristics of urban ecological resilience in the Yellow River Basin from 2011 to 2020 using kernel den-sity estimation,Dagum Gini coefficient,and other methods.Moreover,it applies the spatial Durbin model to ana-lyze its influencing factors.The results showed that:(1)The urban ecological resilience in the Yellow River Basin was effectively improved,and the evolution process and polarization characteristics of the downstream,mid-stream,and upstream were different.(2)The spatial pattern of urban ecological resilience showed a"downstream-midstream-upstream",gradient decline,with obvious characteristics of spatial agglomeration and regional differ-entiation.(3)The overall and intraregional differences in urban ecological resilience fluctuated,and inter-regional differences were the main source of spatial differences,with an annual contribution rate of 65.44%.(4)Precipita-tion,economic development level,and public security construction positively impacted the improvement of urban ecological resilience in the Yellow River Basin,and the opening up level had a positive spillover effect.Infrastruc-ture construction and government intervention also showed a positive spillover effect in improving local urban ecological resilience,whereas the intensity of land development and the degree of environmental pollution would hinder the enhancement of urban ecological resilience.The degree of environmental pollution also had a negative spillover effect.In addition,significant differences were observed in the effects of the influencing factors in the downstream,midstream,and upstream of the Yellow River.
