Abstract: Based on the meteorological data of 38 meteorological stations from 1971 to 2005 in the main rice production areas of Heilongjiang Province,taken the temperature,precipitation and sunshine as the main meteorological factors,the spatial and temporal,annual and inter-decade changes of the average temperature,precipitation and sunshine in the west,the south and the middle-south rice areas of Heilongjiang Province were analyzed.The results showed that the average temperature increased by 0.9℃in growth period of rice over last 35 years due to the global warming.The rate of the temperature increase was by 0.3℃ per decade.The annual change of the precipitation widely fluctuated.The precipitation increased from 1970s to 1990s,while it decreased until the beginning of the 21 century.The sunshine duration during the growing period of the rice decreased in 1980s,increased in 1990s and decreased since the beginning of the 21 century.Due to the global warming,all growing periods of rice except for the heading and maturity period had been advanced with the time lapse.The temperature was a main meteorological factor which influenced on a bumper crop of rice or rice failed in Heilongjiang Province.
