| 摘 要： | 为充分利用热量资源，以有效提高临汾市的农业生产效率，利用临汾市17个地面气象站1981—2010年逐日气温资料，采用线性倾向估计法、滑动平均法、Mann-Kendall（M—K）法，分别对年平均气温、日较差及≥0℃积温和≥10℃积温等表征热量条件的资料进行分析。结果表明：临汾市年平均气温呈上升趋势，增温速率为0．44℃／10年，增暖主要出现在春季及冬季，增温速率分别为0．603％／10年和0．49℃／10年，年平均气温及其气候倾向率的空间分布为中部平川地区高于东部山区和西部山区，临汾市区最高；临汾市年平均日较差以0．18℃／10年的速率增加；临汾市≥0℃活动积温的增加速率为137．21℃／10年．≥10℃活动积温增加速率为101．77℃／10年；由M—K检测可知，临汾市年平均气温及全年≥0℃活动积温显著性增加，在20世纪末期显著上升趋势超过0．001显著性水平，而全年≥10℃活动积温增暖趋势仅在2008年之后超过0．05显著性水平。

| Abstract: | Heat resources are indispensable for agricultural environment and agricultural stabilization. Based on the daily air temperature data of 17 meteorological stations from 1980 to 2010, the heat condition was analyzed such as annual average temperature, diurnal range, annual accumulated temperature ≥0℃ ands≥ 10℃, by using linear-trend estimate, moving average method, Mann-Kendall （M-K） method. The results showed that： the annual average temperature appeared upward trend in Linfen City, the rate of warming was 0.44 ℃/10 years, warming occurred mainly in spring and winter, the rates of warming were respectively 0.603℃/10 years and 0.49℃/10 years, the annual average temperature and climate tendency of the central plain was higher than the eastern mountains and the western mountains in the spatial distribution, and Linfen city was highest; the average daily range increased at the rate of 0.18 ℃/10 years; Linfen City, the annual accumulated temperature ≥ 0℃ increased at rate of 137.21 ℃/10 years, the annual accumulated temperature ≥10℃ increased at rate of 101.77℃/10 years; M-K test method derived, the annual average temperature and the annual accumulated temperature ≥0℃ increased significantly, the trend at the end of the 20th Century was higher than the significance level of 0.001, but the warming trend of the annual accumulated temperature ≥ 10℃ was only higher than the significance level of 0.05 after 2008. |
