Climate change affected regional crop production.Jiangxi province was one of the most important riceproducing provinces in China.The rice production in Jiangxi played an important role in local and national food security. Using the data from 81meteorological stations,double-harvest rice yield data of Jiangxi from 1961to 2011,daily temperature and precipitation data from global climate model ECHAM5/MPI-OM,the link was investigated between the climate change and double-rice yield in Jiangxi.The results showed thatsunshine,temperature and precipitation basically met the requirement for rice growth.The accumulated temperature of≥10℃was mainly at positive anomaly since the 21th century.Sunshine hours at late period of rice growth tended to decrease since the 1990s.The occurrences of the forced ripeningby high temperature significantly increased,while the cold dew wind significantly decreased since the 21th century.The climate-yield model was established for predicting rice production from 2015to 2100.It was found that the early rice meteorology yield was mainly positive value before 2060,but waving after that year.The change degree at late rice yield was smaller than that of the early rice.
