Driving Mechanism and Regulation of Utilization Coefficient of Irrigation Water in Ningxia Pumping Irrigation Area
Based on the relevant data from the Hongsipu,Guhai,Gukuang,and Yanhuanding lift irrigation areas in Ningxia from 2015 to 2019,this study employed an improved STIRPAT model to investigate the irrigation water use coefficients of the four lift irrigation areas.It analyzed the effects of anthropogenic factors on the irrigation water use coefficients of the irrigation areas and predicted the variation patterns of irrigation water use coefficients under the combined influence of anthropogenic and climatic factors.The results indicate that a regulation strategy primarily focuses on developing water-saving areas not only enhances irrigation water use coefficients but also achieves favorable economic benefits.
