黄河流域资源型城市碳生态安全水平测度及时空分异研究
Research on Level Measurement,Spatio-Temporal Differentiation of Carbon Ecological Security in Resource-Based Cities of the Yellow River Basin
摘要
Abstract
It is aimed to provide references for the integrated and coordinated advancement of carbon ecological security and high-quality economic development in resource-based cities of the Yellow River Basin.Based on panel data from 37 resource-based cities from 2012 to 2021,the TOPSIS model and the Kernel Density Estimation model were employed to evaluate the carbon ecological security level and ana-lyze its spatio-temporal distribution pattern.The σ and β convergence models were further used to reveal its evolution characteristics.The results show that:a)Carbon ecological security level is increasing in resource-based cities year by year,evolving from a phase of moderate increase to one of rapid growth,and an obvious"catch-up"effect is in resource-based cities of the middle and downstream.b)The differ-ences in carbon security levels are gradually narrowing among resource-based cities in the upstream and downstream,but the differences in the middle reaches are not obvious.c)Carbon ecological security in resource-based cities of the Yellow River Basin shows σ and β conver-gence trend,which has the characteristic of"downstream resource-based cities being higher than upstream and middle reaches"in terms of convergence reduction and convergence degree.It is suggested that resources-based cities in the Yellow River Basin should break adminis-trative boundary constraints from a holistic perspective,enhance regional correlation,develop differentiated paths,plan collaborative pro-motion,strengthen catch-up effects,improve convergence levels,so as to achieve the balance of carbon ecological security across the en-tire basin.关键词
