The spatial–temporal evolution and influencing factors of the coupling coordination of new-type urbanization and ecosystem services value in the Yellow River Basin

Abstract

A healthy ecosystem is an important support for building a new-type urbanization (NTU). Clarifying the coupling and coordination degree(CCD) between NTU and ecosystem service value (ESV), paying attention to the influencing factors of the CCD, can help achieve modernization of harmonious coexistence between humans and nature. This study focuses on the spatiotemporal evolution process of the CCD between NTU and ESV in the Yellow River Basin of China, and explores the factors affecting CCD using the GTWR model, leading to the following conclusions: (1) During the study period, the comprehensive index of NTU and ESV increased annually, forming the trend of “lower reaches > middle reaches > upper reaches” and “middle reaches > upper reaches > lower reaches”. (2) The CCD between NTU and ESV in the Yellow River Basin generally evolved towards high coordination, but most cities exhibited a phenomenon of “lagging ESV.” The spatial distribution pattern of the CCD maintained the trend of “upper reaches > middle reaches > lower reaches” throughout the study period, showing a significant spatial clustering characteristic. (3) The direction and magnitude of influence of various influencing factors vary at different spatiotemporal positions. FIX, FDI, and NDVI are mainly positive influencing factors, and the NDVI is the dominant factor to influence the CCD. ENV and TEM are mainly negative influencing factors.
