| 摘 要： | 通过对德州2008年1月1日～12月31日70 cm高度温度与百叶箱温度的差值分析，发现二者差值存在明显的日变化和年变化：08：00，冬半年，T70比T150低或接近，在-0.58～0.36 ℃变化；夏半年，T70比T150高，在0.52～0.88 ℃变化。14：00，全年T70比T150都高出较多，在1.06～2.00 ℃变化。20：00，全年在-0.51～-1.79 ℃变化。日平均温度差值变化趋势与08：00相似，1～3月和9～12月，二者差值在-0.15～0.41 ℃变化；4～8月在0.46～0.61 ℃变化。由于多数农作物如小麦、大豆、水稻、棉花、辣椒、茄子、西红柿等的生长高度在70 cm左右，所以70 cm高度温度更能为其建立生长、发育、成熟、采摘的气象指标。由此说明，气象部门不但要保留原来的百叶箱温度观测，还应该根据当地规模化生产特点开展相应层次的气象要素观测，为防灾减灾提供更加准确的气象观测数据。

| Abstract: | Based on analyzing the differences between temperature at 70 cm and thermometer screen temperature in Dezhou from Jan.1st -Dec. 31st 2008, we found that there differences exists an obvious diurnal and annual variation: 08:00, winter half year, T70 was lower than in T150 or close to, variation among -0.58-0.36 ℃; summer half year, T70 was higher than in T150, variation among 0.52-0.88. 14:00, T70 was higher more than T150 throughout the year, variation among 1.06-2.00 ℃. 20:00, throughout the year among -0.51-1.79 ℃. Change trend of daily mean temperature difference was similar to 08:00, Jan.-Mar. and Sep.-Dec., the difference variation among -0.15-0.41 ℃; Apr.-Aug. between 0.46-0.61 ℃. Since majority crops' growth height was about 70 cm, such as wheat, soybean, rice, cotton, pepper, eggplant. Temperature at 70cm are more suitable for meteorological index establishment of growth, development, maturity, picking, which shows that we should not only retain the original thermometer screen temperature observation, we should also carry out appropriate level meteorological elements observation according to characteristics of local large-scale production, providing more accurate meteorological observation data for disaster prevention. |
