Abstract:: Based on the meteorological data of 54 stations from 1963 to 2012 in Xinjiang, the water requirement of wheat (WRW) of the whole growing period and different growth stages were calculated by using FAO Penman-Monteith model and crop coefficient. Meanwhile, we used the methods of linear regression, Mann-Kendall test and Inverse Distance Weighting to analyze the spatiotemporal change characteristics of water requirement of wheat in Xinjiang in recent 50 years. The results showed that the spatial distribution characteristics of mean WRW of the whole growing period and different growth stages of wheat were obviously various in the different regions of Xinjiang. Generally, the WRW of the whole growing period was larger in south than that in north, and it was larger in east than west. And the WRW of the initial or development stage were larger in south than northern. However, the WRW of the mid-season or late-season stage were larger in east than west. The annual WRW of the whole growing period was significantly decreasing with the rate of 7.8 mm/10 a, and it had significantly abrupt decrease in 1978. The negative trend in wheat water requirement in Xinjiang was mainly attributed to decline of sunshine hour and wind speed.
