Abstract

The changed climate resource due to the climate change will impact the agricultural production in China in future. Based on the emission scenarios of greenhouse gases – A2 and B2, and by using RCM (Regional Climate Model) – PRECIS and CERES-Wheat model, the paper simulated the impacts of climate change on the winter wheat yield variability at North China, and simulated the performance of two adaptation options under climate change scenarios. The results shows: maximum yield, average yield as well as the yield variability will increase under both A2 and B2 climate change scenarios at all periods. Advancing the sowing date and changing to the middle-term cultivars can decrease the yield variability, stabilized the yield.
