摘要:
[Objective]The aim was to study variation characteristics of thermal resources in east Hexi Corridor in recent 50 years. [Method]Using the daily average air temperature data from 5 meteorological stations in east Hexi Corridor from 1959 to 2010, the variation of accumulated temperature steadily above 10 and 0 ℃, lasting days, the beginning and ending day were summarized, and then the variation characteristics of thermal resources under the background of climate warming were analyzed. [Result] The air temperature increased continuously in east Hexi Corridor, and the climatic trend rate of the annual average air temperature was 0.34 ℃/10 a, more significant than any other region in China. And it was well correlated with the thermal resource indexes such as the accumulated temperature steadily above 10 and 0 ℃, and their lasting days, and the beginning and ending day. Climate warming had made the accumulated temperature steadily above 10 and 0 ℃ increased significantly in east Hexi Corridor widespread. The accumulated temperature steadily above 10 and 0 ℃ had increased significantly. The lasting days of accumulated temperature steadily above 10 and 0 ℃ increased significantly too. The delay of ending days was more significant than the advancing of beginning days. [Conclusion]These changes in thermal resources were conductive to increase food production and maintain the stability of food production in east Hexi Corridor.
