基于PSR模型的长三角地区城市生态韧性时空演进及空间差异分析
Spatio-temporal Evolution and Spatial Differences of Urban Ecological Resilience in the Yangtze River Delta Region Based on the PSR Model
摘要
Abstract
An evaluation system for urban ecological resilience was developed using the entropy and CRITIC methods to assess the level and evolution of resilience in 27 cities across the Yangtze River Delta Region from 2013 to 2022.Using a spatial autocorrelation model and the spatial Gini coefficient,explore the spatial agglomeration types and regional differences of ecological resilience.The results indicate that during the research period,the level of urban ecological resilience development in the Yangtze River Delta Region showed an upward trend,character-ized by a spatial distribution of'high in the west and low in the east';overall,urban ecological resilience demon-strates a positive spatial correlation,with spatial agglomeration types primarily characterized by high-high agglomer-ation and low-low agglomeration;in terms of spatial differences and decomposition,Anhui has the most significant regional differences and the most obvious agglomeration phenomenon.Inter-regional differences are the main source of overall differences in ecological resilience levels.关键词
