摘要
[目的]研究沧州市国家一般气象站草面温度变化。[方法]利用沧州市国家一般气象站2008～2012年草面温度资料，采用折线图、趋势图等方法，对草面温度变化趋势进行分析。[结果]草面平均、草面最高、草面最低温度月气候倾向率分别为0．572、0．299、0．828℃／a，均为上升趋势，年平均值分别为13．9、29．8、4．5℃，气候倾向率分别为-0．900、8．600、-2．500℃／a，年平均草面最高温度为31．7℃，年平均草面最低温度为3．9℃，均出现在2012年；四季平均值春季分别为16．2、34．0、4．9℃，夏季分别为28．4、44．7、19．5℃，秋季分别为13．9、29．0、5．4℃，冬季分别为-2．9、11．7、-11．7℃，气候倾向率夏季均为上升趋势，冬季均为下降趋势，春季和秋季仅草面最高温度为上升趋势；年平均温度地温〉草温〉气温，年平均最高温度草温〉地温〉气温，年平均最低温度草温〈地温〈气温，年极端最高温度地温〉草温〉气温，年极端最低温度草温〈地温〈气温。[结论]该研究为气候资料使用者提供科学依据。
[ Objective ] The research aimed to study the grass surface temperature changes in Cangzhou national ordinary station. [ Method ] Based on the grass surface temperature observation data of national ordinary station in cangzhou from 2008 to 2012, using a line chart, trends and other methods,the change trends of the grass surface temperature were analyzed. [ Result ] The monthly climatic trend rate of the average, highest and lowest grass surface temperature were 0. 572,0. 299,0. 828 ℃/a, they presented increasing trend. The annual average of the aver-age, highest and lowest grass surface temperature were 13.9,29.8,4.5 ℃ and climatic trend rate were -0. 900,8. 600, -2. 500 ℃/a. The annual average of the highest and lowest grass surface temperature were 31.7,3.9 ℃ ,that all appeared in 2012. The average value of spring, summer, autumn and winter were 16.2,34.0,4.9 ℃ ,28.4,44.7,19.5 ℃, 13.9,29.0,5.4 ℃, - 2.9,11.7, - 11.7 ℃. The climatic trend rate showed an up trend in summer, that was decreasing in winter, and only the highest grass surface temperature on the rise in autumn and spring. The highest average annual temperature was ground temperature. The annual mean maximum and minimum temperature of grass land temperature were compared. [ Conclusion ] The study provides the theoretical basis for climate data users.
