This study predicted the temporal and spatial change of climatic resources and production potential during growth period of rice under the background of global climate change in Sichuan Province to provide theoretical support for addressing climate change and making policy for rice production.[Method] Based on the daily data of A2 and B2 climate scenarios (2071-2100) and baseline climate condition (1961-1990) from the regional climate model PRECIS,the spatial and temporal change characteristics of climate resources (thermal time ≥10 ℃,total sunshine hours,total precipitation,reference crop evapotranspiration and water deficient ratio) and production potential (photosynthetic potential productivity,photo-temperature potential productivity and climatic potential productivity) during rice growing period in Sichuan were analyzed using the methods recommended by FAO and HOU Guang-liang.[Result] The thermal time ≥10 ℃,total sunshine hours and reference crop evapotranspiration during growth period of rice increased from 2071 to 2100 under A2 and B2 climate scenarios compared with the baseline climate conditions from 1961 to 1990.The precipitation decreased in most regions of Sichuan.The water deficient ratio of rice showed increasing tendency in the future,indicating that the rice drought disaster risk might increase in Sichuan.The photosynthetic potential productivity,climatic potential productivity and photo-temperature potential productivity of rice also increased in future.[Conclusion] Future changes in climatic resources would benefit rice yield in Sichuan Province.
