摘　　要：简要阐述了自20世纪70年代以来河北省小麦生产的发展、小麦节水栽培技术的研究成就和历史沿革及农业对水资源利用的变化等特点。研究表明小麦用水量下降和产量提高呈协同发展变化模式。因此,通过综合节水技术的运用,在水分高效利用的前提下,可使小麦增产,实现节水和粮食安全双赢。The development of wheat production of wheat water-saving cultivation techniques, the research achievements, historical evolution and changes of water resource used by agriculture in Hebei Province since 1970＇s were briefly introduced. The analysis revealed a change pattern of coordinated development in the decrease of water consumption and increase of yield in wheat production. It could increase the wheat yield and realize the win-win of water-saving and food security that using comprehensive water-saving techniques by the premise of high water use efficiency.
