Abstract:

Climate change, causing transformation of climate resources, results in food security problem. The coupling of regional climate model with crop growth model can be used to quantitatively analyze crop yield variability under climate change, and to propose suitable field management for maintaining crop yield. Taking northwest plain of Shandong Province, which is one of the major food producing areas of China, as a research region, this study analyzed effect of climate change on winter wheat yield and its adaptation measurement under A1B climate change scenario, by means of coupling regional climate model with crop growth model. The results shows winter wheat yield will decrease under A1B climate change scenario. Taking the measures of cultivating new variety with a character of less sensible to vernalization, appropriate advancing sowing date and increasing the amount of overwintering irrigation can yield security and reduce annual variability.

Key words: climate change, winter wheat, yield, adaptation measurement
