黄河流域城市紧凑度对碳排放绩效的影响
Impact of urban compactness on carbon emission performance in the Yellow River Basin
摘要
Abstract
Under the framework of China's"double carbon"goal,moderately compact urban development is considered the optimal approach for achieving green,low-carbon,and high-quality growth in the Yellow River Basin.Considering 77 prefecture-level cities in the Yellow River Basin as examples,this study constructed a com-prehensive evaluation index system across several dimensions such as population,economy,and society.Employ-ing the entropy weight technique,comprehensive weighted summation model,kernel density estimation,bivariate spatial autocorrelation analysis,spatiotemporal weighted regression model,and a geographical detector,this study analyzed the effects and mechanisms of urban compactness on carbon emission performance in the Yellow River Basin from 2005 to 2021.The results are as follows.(1)From 2005 to 2021,both the urban compactness and carbon emission performance in the Yellow River Basin slightly increased.Urban compactness exhibited a spatial distribution pattern of"lower in the upper and middle reaches,and higher in the lower reaches",whereas carbon emission performance exhibited a pattern of"lower in the middle reaches,and higher in the upper and lower reaches".(2)The correlation between urban compactness and carbon emission performance varied signifi-cantly across time and space in the Yellow River Basin from 2005 to 2021.Most cities demonstrated a negative spatial correlation,with the number of such cities increasing over time in the Yellow River Basin.Cities of the Yellow River Basin with positive spatial correlation between urban compactness and carbon emission perfor-mance were mostly located in the middle and lower reaches.(3)The negative impacts of land use compactness and population compactness on carbon emission performance were relatively obvious in the Yellow River Basin from 2005 to 2021.The negative impact of land use compactness weakened.For population compactness,the neg-ative impact increased in the mid-upper reaches regions but weakened in the downstream regions.The economic compactness and transportation compactness mainly had positive impacts on carbon emission performance,yet the areas with negative impacts of transportation compactness increased both in the upstream and downstream re-gions.(4)The influence of urban compactness on the carbon emission performance was enhanced when interact-ing with other socioeconomic factors in the Yellow River Basin from 2005 to 2021.Synergies among various fac-tors considerably affected the carbon emission performance.The greatest combined effect was observed between the economic compactness and energy consumption levels.Thus,to promote coordinated development in the Yel-low River Basin,differentiated urban compact development strategies must be implemented based on regional conditions.Further,efforts should focus on the optimization of industrial structures,improvement of urbanization quality,fostering of low-carbon technology innovation,and dynamic adjustments of urban compactness.These measures are aimed at promoting balanced economic growth,social welfare,and low-carbon development across the entire basin.关键词
