Abstract
The rapid development of tourism has caused a series of impacts on the ecosystem. Although studies on the relationship between tourism development (TD) and the ecological environment are rich, few scholars have focused on the coupling coordination between them from the perspective of ecosystem services value (ESV). Given this research gap, we evaluated the levels of TD and ESV in 78 cities of the Yellow River Basin (YRB), China based on statistical and land-use data. Then, the coupling coordination degree (CCD) model, exploratory spatial data analysis (ESDA), the spatial variogram model, and the obstacle degree model were used to analyze the spatiotemporal evolution of coupling coordination between TD and ESV and its obstacle factors. The results show the following: (1) The comprehensive TD level shows an upward trend and presents significant spatial differentiation characteristics. The total ESV of the YRB shows a fluctuating upward trend, and the average ESV presents the spatial pattern of uplift in the middle reaches. (2) The comprehensive CCD of the YRB has gradually improved, but the gap between cities has widened. The global spatial autocorrelation of CCD is significantly positive, and the spatial variability has gradually increased. An “uplift area” in southern Shaanxi always exists and has gradually expanded to Shanxi and western Henan, while eastern Henan and western Shandong become a “subsidence area”. The coupling coordination level has changed from uncoordinated to coordinated in most counties, but the problem of TD and ESV imbalance generally exists. (3) For the whole basin, TD is always the main obstacle factor at the system layer, and tourism scale and tourism economic benefit are the most significant obstacles at the category layer. At the city level, the proportion of cities where TD is the main obstacle factor exceeds 80% by 2019. Specifically, insufficient tourism scale and low tourism economic efficiency restrict the improvement of CCD in most cities. This research provides valuable references for studying the coupling coordination relationship between TU and ESV in big river basins worldwide.
