基于PSR模型的黄河流域城市生态韧性时空分异特征研究
Research on the spatiotemporal differentiation characteristics of urban ecological resilience in the Yellow River Basin based on PSR model
摘要
Abstract
[Objective]Analyzing the evolution of urban ecological resilience in the Yellow River Basin holds significant practical significance for ensuring ecological security and promoting high-quality development in the region.[Methods]Based on the Pressure-Status-Response(PSR)model framework,methods including combination weighting and spatial autocorrelation analysis were used to measure the urban ecological resilience of the Yellow River Basin from 2010 to 2020,and its spatial-temporal evolution characteristics were also analyzed.[Results](1)The urban ecological resilience index of the Yellow River Basin showed a fluctuating growth trend as a whole,with the average value rising from 0.375 6 to 0.425 1,and the resilience values of each subsystem also showed an upward trend.The level of urban ecological resilience in the upper,middle,and lower reaches was significantly different,with the lowest resilience in the upper reaches and relatively higher overall resilience in the middle and lower reaches.(2)The grade of urban ecological resilience in the Yellow River Basin exhibited a distribution characteristic of agglomeration and contiguity,and the spatial pattern gradually evolved from low-resilience agglomeration and high-resilience dispersion to high-resilience agglomeration and low-resilience dispersion.The level of ecological resilience and the growth rate of resilience among cities were significantly different and obviously differentiated,with a dominant number of cities falling into the'high level-high growth'and'high level-low growth'categories.(3)In terms of spatial relationship,except for 2018,the ecological resilience index of the Yellow River Basin exhibited positive spatial autocorrelation,and the agglomeration effect showed an increasing trend.From the perspective of local spatial autocorrelation,the spatial agglomeration mode of urban ecological resilience was generally stable,but there were spatial transitions in some cities.[Conclusion]The urban ecological resilience in the Yellow River Basin continuously improves as a whole,and the number of cities with high resilience and relatively high resilience continues to increase and occupies a dominant position.However,the growth of urban ecological resilience among sub-basins is uneven,and regional coordinated development has not yet been achieved.关键词
