Driving factors and decoupling effect of water resources utilization in the Yellow River Basin
Realizing the sustainable utilization of water resources is a critical aspect of ecological protection and high-quality development in the Yellow River Basin,China.This study uses water footprint theory and methodol-ogy to measure the actual water consumption of 56 cities in the Yellow River Basin from 2000 to 2020.It identi-fies the primary factors influencing water use changes with the logarithmic mean Divisia index method and con-structs a decoupling effort index model based on the driver-pressure-state-influence-response framework to evalu-ate the decoupling effect of water resource utilization.The findings reveal the following:(1)The utilization of wa-ter resources in the Yellow River Basin exhibits a fluctuating upward trend from 2000 to 2020,with agricultural production water accounting for over 90%of the total consumption.(2)The economic development effect and population scale effect are the primary positive driving factors,while the water use intensity effect and industrial structure effect serve as the main negative driving factors.(3)The decoupling effect between water resource utili-zation and economic development in the Yellow River Basin is generally favorable,primarily characterized by weak and strong decoupling.The decoupling performance is better in the midstream and downstream regions compared to the upstream region,and industrial production water and service trade water demonstrate superior de-coupling compared to agricultural production water.(4)In the transition process of the decoupling effect of water resource utilization,the industrial structure effect and water resource endowment effect are decisive for achieving regional decoupling,while the water use intensity effect and water resource endowment effect are critical for achieving industrial decoupling.The results offer a theoretical basis for the coordinated development of water re-sources and the economy in the Yellow River Basin.
