Abstract: Abstract: Fujian Province is divided into three paddy rice planting areas with 19 sampling points been chosen. In the past 5 years from 2000 to 2004, yielding on odd years has been used to commission the CERES-Rice module parameter while yielding on even years has been used to check the module’s adaptability in the research area. The climate change of each sampling point in 2030 and 2050 has been generated referring to the output of GISS GCM Transient Run. CERES-Rice nodule has been run under all situations. The spice stimulations has been compared with that of the current climate and together with transpiration ration (β) and fluctuation of grain yielding (F), quantity analyzing is made to introduce the influence of gradual change of climate has on the production of rice in Fujian province; and based on this, certain possible solutions are forwarded. The research shows that in the process of climate change in the future, (1) the soil during the growth season of the rice in the research area would be less moist; (2) the production period of the early rice and single cropping rice would be shortened more or less while that of the late season rice would be prolonged in the climate situation of 2050; (3) the yielding of double cropping rice in southeast and northwest Fujian province would be lessened in both two climate situations in 2030 and 2050 with the production reduction rate increases when the temperature increases; and the yielding of single cropping rice in the mountainous areas of northwest Fujian province may enjoy a production enhancement; (4) as for the stability of yielding, currently those in the southeast of Fujian province is the worst and in the double cropping area in northwest Fujian is better; and the yielding will be less stable in the future climate change; (5) the total yield of rice in Fujian province will be decreased with the increase of temperature in both two future climate situations.
