Article Preview

That there existed time and spatial variation for winter wheat water use efficiency (WUE) in different scales in irrigation area could be concluded by studying winter wheat WUE in small scale, middle scale and large scale in irrigation area in 2004~2006 in this paper. It indicated that winter wheat WUE were much more different in the small, the middle and the large scales in different years, which were 1.61kg/m3, 1.30kg/m3 and 0.88kg/m3, respectively. With up scaling, winter wheat WUE was declining in 2004, while increased firstly and then declined in 2005 ~2006.
