中国三大城市群植被覆盖度与地区生产总值协调发展研究OA北大核心CSTPCD

In order to explore the effect of the coupling and coordinated development of fraction vegetation coverage and regional GDP on the construction of urban ecological civilization,48 cities in the Yangtze River Delta,Beijing-Tianjin-Hebei and Pearl River Delta were taken as the research objects,and the coupling and coordination degree model of vegetation coverage and regional GDP was constructed.The Theil-Sen Median trend analysis,Mann-Kendall mutation test and geographical detector model were used to reveal the coupling development changes and driving factors of vegetation coverage and regional GDP in three urban agglomerations from 2000 to 2020.The results show that the vegetation coverage and regional GDP of the three urban agglomerations mainly show fluctuating growth,and the development status of the two is unbalanced.The coupling coordination degree between vegetation coverage and regional GDP has basically changed from extreme imbalance to high coupling,showing a steady upward trend.Land use type and nighttime light data are the main driving forces affecting the coordination between vegetation coverage and regional GDP in urban agglomerations.The interaction between carbon dioxide emissions and elevation has the highest explanatory power,reaching 67%.The research conclusions provide a reference for the coordinated development of urban economy and ecological civilization construction.
