| 摘 要： | 利用平凉黄土高原沟壑区7站1959-2008年平均最高、最低气温资料,采用线性倾向估计法和累积距平法,分析了最高、最低气温和日较差的长期变化趋势,对气候变化过程有了进一步的认识,用Mann-Kendall法对气候突变进行了检测。结果显示:平均最高、最低气温呈上升趋势,与全球和全国变暖趋势一致,气温日较差与全国减小趋势相反;气候的变化过程分三个阶段,20世纪70年代以前为气候偏冷期,80年代开始转暖,90年代明显变暖;最高、最低气温分别在1999年和1994年发生变暖突变。

| Abstract: | Based on observed data of mean monthly maximum and minimum air temperature in 7 meteorological stations of Pingliang gully region of Loess Plateau from 1959 to 2008,the long - term trends of maximum and minimum air temperature and diurnal range of temperature were analysed by using the metheods of linear tendency and cumulative anomaly,and the further understanding to climatic change was obtained. By using the metheod of Mann - Kendall,the abrupt changes of climate were tested. The results showed that maxim... |
