黄河流域生态保护和高质量发展评价及影响因素分析OA

Scientifically quantifying the comprehensive level of ecological conservation and high-quality development in the Yellow River Ba-sin and identifying its key influencing factors can provide a scientific basis for policy optimization and regulation.Based on data from nine provinces(autonomous regions)in the Yellow River Basin from 2011 to 2023,this study used the entropy weight method to measure the eco-logical conservation and high-quality development index(comprehensive index)for each province.The Dagum Gini coefficient was employed to analyze regional disparities,and the obstacle degree model was applied to identify the main influencing factors.The results show that:The overall comprehensive index of the Yellow River Basin exhibits an increasing trend,yet remains at a moderately low level.There is significant spatial heterogeneity in the comprehensive indices of the upper,middle,and lower reaches,generally following the pattern of lower reaches>middle reaches>upper reaches.The comprehensive indices of the nine provinces(regions)show pronounced spatial differentiation,with Shandong,Henan,and Sichuan exhibiting relatively high indices with stable growth rates,while Ningxia has the lowest index and the slowest growth rate.The overall Dagum Gini coefficient of the comprehensive index in the Yellow River Basin shows an upward trend,indicating con-tinuously widening overall disparities,which mainly stem from inter-regional differences.The comprehensive index for the Yellow River Basin is primarily determined by a combination of key factors,including the completeness of flood control engineering systems,the level of innova-tion capability,the intensity of water resource exploitation relative to ecological redlines,and the degree of flood risk.
