Cold/Warm Change Characteristics in Crop Growing Season in Heilongjiang Province during 1961-2009
摘要
Abstract
[Objective] The aim of the study was id 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 a-bove 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 wan 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 13 ℃, and the beginning dale has advartted 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 signifirant period of climate wanning 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 pact 49 years, providing more favorable climatic conditions for the agricultural production.关键词
