黄河下游农业生态用水效率及其与经济发展脱钩关系研究
Study on the Spatial-Temporal Evolution and Decoupling Effect of Agricultural Ecological Water Use Efficiency in the Lower Yellow River
摘要
Abstract
Revealing the spatial-temporal distribution characteristics of agricultural ecological water use efficiency in the Lower Yellow River and clarifying the decoupling relationship between agricultural ecological water use efficiency and economic development can promote high-quality agricultural development.The SBM model of unexpected output and ArcGIS software were adopted to analyze the spatial-temporal evo-lution law of agricultural ecological water use efficiency in the Lower Yellow River from 2013 to 2022.The Tapio decoupling model and the LMDI model were used to explore the decoupling status of agricultural ecological water use efficiency and agricultural economic development.The results show that the average efficiency of agricultural ecological water use in the Lower Yellow River decreases from 0.616 to 0.509,showing an overall fluctuating downward trend.The spatial distribution presents a pattern of being high in the east and west and low in the middle.The overall difference in agricultural ecological water use efficiency in the Lower Yellow River has widened,and regional differences are the main source of overall differences.The overall decoupling trend between agricultural ecological water use efficiency and economic de-velopment is strong,and the decoupling state is not ideal.Technological effects promote decoupling,while agricultural water use intensity and cultivation scale inhibit decoupling.关键词
