Zusammenfassung:Climate change and its effects are the major concerns among researchers in a variety of fields. A large quantity of rice is produced in Heilongjiang Province,China; however,the yield and quality can be adversely affected by low temperatures. Heilongjiang Province shows obvious signs of climate warming. Therefore,in the context of climate change,understanding the causes cold damage of rice at booting and heading stages leading to sterility could provide scientific basis for reliable rice production in Heilongjiang Province. We analyzed the influences of climate change cold-damage induced sterility in rice in Heilongjiang Province. Using meteorological data from 70 weather stations during the period between 1971 and 2012 and rice phenology data from 10 of these stations between 1980 and 2011,rice phenological parameters for the other 60 stations were estimated. This was done by applying the phenology law proposed by A. D. Hopkins combined with indices of cold-damage induced sterility in rice( following meteorol
