| 摘 要： | 利用统计学和气象学原理，对德州2008年1月1日—12月31日德州70 cm高度的气温(用T70表示)与地面温度（用T0表示）中08、14时和20时及日平均资料进行分析。结果表明：冬半年08时T70＞T0（或T70≈T0）；夏半年T70＜T0，6月差值最大，为-2.6℃。14时全年都是T70＜T0，3月差值最大，为-12.1℃。20时全年基本都是T70＞T0。就日平均而言，全年都是T70＜T0。运用回归分析法建立了以T0为基础的T70预测模型，经检验表明，3—9月预测准确率较高，可以满足当地农事需要。

| Abstract: | According to statistics and meteorology theories, air temperature at 70 cm (T70) and ground temperature (T0) from January 1 to December 31, 2008 were analyzed, including 08:00 o’clock, 14:00 o’clock, 20:00 o’clock and daily mean temperatures. The results indicate that T70 is higher than T0 at 8:00 o’clock or both are equal in winter, while it is contrary in summer. T70 is less than T0 at 14:00 o’clock in a whole year, while it is contrary at 20:00 o’clock. The largest differences at 8:00 and 14:00 reach -2.6℃ and -12.1℃, and they occur in June and March, respectively. The daily average of T70 is less than that of T0 in a whole year. A forecast model on T70 is established by regression method based on T0. The forecast on T70 is accurate from March to September, which could meet the local farming needs. |
