摘　　要：[Objective] The aim of the study was to find out the cold/warm change characteristics in crop growing season and their relationship with food production in Heilongjiang Province.[Method] The temporal and spatial variation on the accumulated temperature steadily above 10 ℃ and its lasting days,the beginning date,the ending dates were investigated,and the relationship between food production and cold/warm climate in Heilongjiang Province during 1961-2009 was further analyzed.[Result] The results showed that the provincial average accumulated temperature steadily above 10 ℃ has increased by 355.4 ℃,the lasting days of accumulated temperature steadily above 10 ℃ has extended by 13d,and the beginning date has advanced by 8 d,while the ending date has delayed by 5 d in Heilongjiang Province during 49 years.Climate warming began from the 1980s,and the most significant period of climate warming was after the 1990s.The food production is closely related to cold/warm climate in Heilongjiang Province.[Conclusion] The climate warming was significant in crop growing season of Heilongjiang Province in the past 49 years,providing more favorable climatic conditions for the agricultural production.[目的]了解黑龙江省作物生长季冷暖变化特征及其对农业生产的影响。[方法]研究1961～2009年黑龙江省10℃积温及其持续日数、初日、终日时空变化特征,并分析黑龙江省粮食产量与气候冷暖的关系。[结果]在49年中,黑龙江省平均10℃积温增加355.4℃,持续天数延长13d,初日提前8d,终日延后5d;20世纪80年代以后黑龙江省作物生长季开始增暖,90年代以后是变暖最明显时期;黑龙江省粮食产量与气候冷暖的相关性很好。[结论]近49年黑龙江省作物生长季显著增暖,为农业生产提供了更有利的气候条件。
