Abstract
Based on the climatic data from 23 meteorological stations throughout the Xiliaohe watershed during1961 and 2010, every month's spring maize water requirement are calculated by Penman-Monteith model, In addition, Spatial distribution of water requirement in Xiliaohe watershed can be analyzed using the Mann-Kendall and Ordinary Kriging method. Conclusions are as follows: Water requirement in Xiliaohe watershed is positive correlation relationship with T-max, mean wind speed and hours of sunshine. It's negative correlated relationship with relative average humidity; As a whole, water requirement in the study area is on the decline. Every month's spring maize water requirement first increased and then decreased. Water requirement is highest in July and is lowest in May; The spatial distributional trend of water requirement is that water requirement decreased from mid-east region to all around. Water requirement is larger,the crop take more risk.
