Urban ecological resilience,social networks and its influencing factors in the Yellow River Basin
The social network of urban ecological resilience and its influencing factors were analyzed to promote regional green synergistic development.Data from 2012 to 2021 for 63 prefecture-level cities in the Yellow River Basin,China,were used to construct a pressure-state-response model.The CRITIC-TOPSIS method,gravity mod-el,and multi-scale geographic weighting model were applied to examine the ecological resilience of cities in the Yel-low River Basin,the linkage relationships,and the influencing factors.The results reveal the following:(1)The eco-logical resilience of the Yellow River Basin fluctuates around 0.5,with the pattern"upstream>downstream>mid-stream",and the average annual increase rates of each river reach was 0.41%,0.30%,and 0.40%,respectively.(2)The Yellow River Basin is divided into seven major city networks(N1-N7).The degree of basin agglomeration and city association increases sequentially from the upper to the lower reaches.(3)Considering the influence of direct effect,regulatory effect and substitution effect,industrial structure upgrades significantly enhance the urban eco-logical resilience of city networks N1-N4,with impact coefficients of 0.4213,0.4210,0.5085,and 0.8883,respec-tively.In contrast,industrial structure rationalization more effectively enhances the ecological resilience of city networks N5-N7,with impact coefficients of 0.8483,0.5669,and 0.8128.
