中国生态韧性关联网络的特征及影响因素研究
Characterization and influencing factors of ecological resilience linkage networks in China
摘要
Abstract
Using the entropy weight-TOPSIS method,this study evaluates national ecological resilience from 2008 to 2022.The structure and determinants of the provincial ecological resilience network are analyzed through a modified gravity model,social network analysis,and exponential random graph models.The results highlight the following key points:(1)A positive trend in national ecological resilience during the study period.(2)A sub-stantial increase in interprovincial connections,resulting in a more complex spatial network.(3)The central role of Beijing,Shanghai,Jiangsu,Zhejiang,and Guangdong as central nodes,and the northwest China,northeast Chi-na,middle and lower Yellow River,and Central Plains as peripheral nodes.(4)The classification of regions into net beneficiaries(Beijing-Tianjin,Yangtze River Delta);brokers(Zhejiang,Pearl River Delta);net spillover con-tributors(northeast China,the middle and lower reaches of the Yellow River,parts of western China);and two-way spillover areas(middle and lower reaches of the Yangtze River,southwest China).(5)The significant impact of economic development,technological advancement,water source condition,and geographic proximity on net-work formation,as demonstrated by exponential random graph model(ERGM).These results can provide a scien-tific basis for improving the connection and stability of the spatial correlation network of ecological resilience.关键词
