Analysis of the Decoupling Effect of Water Resources Utilization and Economic Development in Nine Provinces of the Yellow River Basin
In order to alleviate the contradiction between water resources and economy in the nine provinces of the Yellow River Basin,and clarify the positive driving factors for the decoupling of water resources utilization and economic development,based on the Tapio decoupling index model and the Kaya-LMDI factor decomposition model,this study analyzed the decoupling status and driving forces of water resources utilization and economic development in the nine provinces of the Yellow River Basin from 2001 to 2020.The results show that a)the total water footprint of the nine provinces within the Yellow River Basin exhibits an upward trend,with agricultural production water accounting for the majority of the water footprint.b)The water resources utilization and economic development of the nine provinces as a whole show a weak decoupling trend,with a relatively favorable decoupling state.On a regional level,the downstream regions exhibit the strongest decoupling state,followed by upstream and midstream regions.c)It suggests that industrial structure and technological advancements serve as positive driving forces for decoupling,while economic development and population size act as negative driving forces.Furthermore,there are noticea-ble spatial disparities in the driving factors of decoupling across different regions.
