| Abstract: | 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. |
