气候变暖背景下临汾地区热量资源变化分析

ccording to linfen region at 17 stations in 1961-2010 average daily temperature data, Calculated the ≥0℃ and ≥10℃ accumulated temperature, and compares ≥0℃ and ≥ 10℃ accum-Lated temperature, Continuous days of change, each years space change,and then Linfen region are analyzed under the background of climate warming heat resources distribution of change. The results show that the ≥ 0℃and ≥ 10℃ accumulated temperature trends and continuous days since the 1980 s has been increased, and the increase trend of plain is greater than the mountain. ≥ 0℃and≥10℃ accumulated temperature of space distribution of high value area of linfen middle plain constantly extended to the whole north and south plains, Under the backg- round of climate warming, the distribution of heat resources in linfen, has produced a certain degree of change.
