黄河流域农业用水效率的时空格局及影响因素研究
Research on Spatiotemporal Patterns and Influencing Factors of Agricultural Water Use Efficiency in Yellow River Basin
摘要
Abstract
[Objective]This study aims to reveal the spatiotemporal patterns and influencing factors of agricultural water use efficiency in the Yellow River Basin and to promote high-quality agricultural development in this region.[Methods]Based on panel data from 2013 to 2022,the undesirable output super-efficiency SBM model was first used to measure and analyze the agricultural water use efficiency of various cities in the Yellow River Basin.Subsequently,the Tobit model was used to an-alyze the influencing factors of agricultural water use efficiency.Finally,the spatiotemporal geographically weighted regression model was used to analyze the degree of influence and spatiotemporal differences of each factor.[Results](1)The agricul-tural water use efficiency in the Yellow River Basin greatly improved in recent years,but it remained at a relatively low level,with significant spatial differences and a distribution pattern of "higher in the east and lower in the west" and "higher in the south and lower in the north".(2)Per capita water resources,proportion of surface water supply,proportion of water-saving irrigation area,and per capita agricultural output value were the main influencing factors of agricultural water use efficiency.(3)The influencing factors of agricultural water use efficiency in the Yellow River Basin exhibited significant spatiotemporal heterogeneity.Per capita water resources primarily exhibited a negative influence,but the degree of this influence gradually weakened from east to west,and in some regions,it even showed a positive influence.The negative influence of the propor-tion of surface water supply first increased and then decreased,showing a spatial distribution characterized by "higher in the west and lower in the east".The positive influence of the proportion of water-saving irrigation area gradually increased,show-ing a distribution pattern of "higher on both sides and lower in the middle".The influence of per capita agricultural output val-ue demonstrated significant spatial heterogeneity.In the middle and lower reaches of the Yellow River,it had a positive influ-ence that gradually intensified,following a distribution pattern of "higher in the east and lower in the west",while in some are-as of the upper reaches of the Yellow River,it exhibited a negative influence.[Conclusion]The agricultural water use effi-ciency in the Yellow River Basin has improved in recent years but remains at a relatively low level,with significant spatial differences.It is greatly influenced by the per capita water resources,the proportion of surface water supply,the proportion of water-saving irrigation area,and the per capita agricultural output value,reflecting complex spatiotemporal dynamic characteristics.关键词
