Coupling Coordination Relationship Between Gross Ecosystem Product and Economic Development in Important Ecological Functional Areas:A Case Study in the Yellow River Basin
This paper selected 63 prefecture-level cities in the Yellow River Basin as research area and constructed accounting system for the Gross Ecosystem Product(GEP)of Yellow River Basin in 2015 and 2020.It explored the coupling coordination relationship between GEP and regional economic development,and revealed the spatio-temporal evolution characteristics of their coupling coordination relationship at different scales.The results showed that:1)The total GEP in the Yellow River Basin demonstrated a rapid growth trend,increasing from 9.19 trillion yuan in 2015 to 9.76 trillion yuan in 2020,the growth rate was 6.2%.This growth indicates an improved ecological quality and a significant enhancement in ecological value in the Yellow River Basin.Moreover,there were substantial differences in GEP spatial distribution among different regions,with no significant regularity.From an administrative viewpoint,the western and northern regions exhibited higher total GEP,while the overall GEP in the eastern and southern regions remained relatively low.2)The overall coupling coordination degree between GEP and regional economic development in the Yellow River Basin displayed a natural transition and gradual change,with higher levels in the east of the Yellow River Basin and lower levels in the west of the Yellow River Basin.The spatial characteristics of relative development showcased a gradual increase from the west of the Yellow River Basin to the east of the Yellow River Basin,indicating that the comprehensive development capacity in the east of the Yellow River Basin surpassed that in the west of the Yellow River Basin thereby reflecting a stronger ability to coordinate ecological and economic development.3)From the perspective of the coupling coordination development changes in cities of the Yellow River Basin,the differences between regions are obvious,it showed the overall characteristics of the transformation from unbalanced development to coordinated development,from the double lag of economy and ecology to the mutual development,indicating that it was gradually moving toward a path of ecological and economic coordination and sustainable development in the Yellow River Basin.It shows that China's implementation of the Yellow River Basin ecological protection and high-quality development strategy has achieved phased results.In the future,government should adhere to the principle of ecological priority and green development,strengthen the regular monitoring of the coupling coordination development of ecological environment and social economy,and apply local policies to effectively promote the ecological protection and high-quality development of the Yellow River Basin.
