Measuring the Co-Evolution of High-Quality Development and Ecological Resilience in the Yellow River Basin and Its Influencing Factors

Ecological resilience (ER) describes the ability of ecosystems to resist, adapt, and recover from external shocks. How to improve ER has become a crucial component of high-quality development (HQD) in the new era. Therefore, there is an urgent need to investigate the synergistic relationship between HQD and ER. In this study, taking the Yellow River Basin as an example, long-term time series data (2008–2022) were used at the provincial scale. Then we developed a logical framework to reveal the interrelationship and intrinsic mechanism between HQD and ER. Next, we explored the spatiotemporal coupling characteristics of HQD and ER using a comprehensive evaluation model and coupling coordination analysis. We found that from 2008 to 2022, the comprehensive level of HQD and ER fluctuated, and the coupling coordination degree showed significant spatial distribution characteristics. Meanwhile, from 2008 to 2022, the spatial evolution level of HQD increased in 89% of the study regions, while ER improved markedly across most regions. Furthermore, using principal component analysis (PCA), we analyzed the driving factors for HQD and ER. The analysis revealed that economic development, green innovation, livelihood improvement, and ecological adaptation play significant roles in promoting the coordinated development of HQD and ER. This research can serve as a reference and methodological guidance for achieving high-quality and sustainable development in the Yellow River Basin.
