Abstract: Based on the WOFOST crop model, jointing the climate simulated data produced by climate model, the simulation research was carried out about the impacts of the climate change on the yields and growth of double-harvest rice in the southern China during the future one hundred years. Results showed that, 1) the life time of double-harvest rice will be shortened owing to climate change; and 2) the yields of double-harvest rice will be decreased to some extent, especially the early rice. But the decreasing rate is not so fast.

Key words: climate change, crop model, double-harvest rice, growth, yields
