| Abstract: |
| This study simulates the growth process of wheat in main wheat growing regions of China from 1961 to 2011 using EPIC (Environmental Policy Integrated Climate) model and analyzes the water stress in the growing period of wheat. The results reveal that the degree and frequency of water stress in winter wheat regions and Northeast spring wheat region except for Xinjiang winter wheat region are significantly lower than the other spring wheat regions. The degree and frequency of water stress in North, Northwest and Middle and lower Yangtze winter wheat regions in the south are lower than those in the other regions. The rule of water stress in Huanghuai and North winter wheat regions are similar, which shows that water stress is higher in January, February, May and June and North winter wheat region is a bit higher than Huanghuai winter wheat region in water stress degree and frequency. North, Northwest, North Xinjiang spring wheat regions especially Xinjiang winter wheat region are regions with most severe water stress. |
