摘　　要：基于2015—2019年宁夏红寺堡、固海、固扩、盐环定扬水灌区的相关数据,借助改进的STIRPAT模型对4个扬水灌区的灌溉水利用系数进行了研究,分析了人为影响因素对灌区灌溉水利用系数产生的影响,并且对人为因素和气候因素综合影响下的灌溉水利用系数变化规律进行了预测。结果表明,以发展节水面积为主的调控策略在提升灌溉水利用系数的同时,可实现较好的经济效益。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.
