In order to provide reference for the policy research of ecological protection and high-quality development in the Yellow River Ba-sin,taking 9 provinces in the Yellow River Basin from 2006 to 2020 as the research object,the evaluation index system of ecological protec-tion and high-quality development was built respectively.It measured by entropy method and explored the coupling coordination relationship and obstacle factors between the two systems with the help of coupling coordination model and obstacle degree model.The results are show that a)the overall trend of ecological protection and high-quality development in the Yellow River Basin is good,but the heterogeneity of each province is obvious.b)The coupling and coordination degree of ecological protection and high-quality development in the Yellow River Basin is on the rise as a whole,but the level is still lower.In terms of time sequence,it has experienced the evolution process of near imbal-ance-barely coordination-basic coordination,and the spatial distribution pattern is downstream＞midstream＞upstream.c)The coupled and coordinated relationship between ecological protection and high-quality development in the Yellow River Basin is mainly constrained by the triple constraints of pollution control,ecological construction and innovative development,and there are differences in the main obstacle fac-tors in each province(region).
