Abstract:Using the Stochastic Weather Generator, the Regional Climate Model was linked with CERES Rice Model to simulate irrigated and rainfed rice yield in China's main rice production areas: Guangzhou, Changsha and Nanjing under future climate scenarios, assuming the concentration of CO 2 was 550mg/L in 2050. Three levels of climate variability for the fertility of CO 2 were taken into account. The simulation results show:(1) The influence of climate variability on rice yield is dissimilar due to differential m...
