【摘要】 根据北京等6个热平衡站的资料，通过5种方案计算比较得出土壤热通量Qs动的气候计算方法Qs＝2．826·△θs-20＋0．486·△T－0．777这里△θs-20、△T分别为土中5与20厘米温差和地一气温差．该式相关比为0．897，平均拟合误差1．4wm-2。据此计算全国215站的土中热交换量，并分析其时空变化，得出一些有意义的结果。更多还原

【Abstract】 Based on the data from six thermal balance stations(at Beijing etc.) and by comparison of the calculated results using five experimental schemes, the climatological calculation method of soil heat flux (Qs) is obtained, that is,Qs = 2. 286△θ5-20 + 0. 486△T -0. 777 where △θ5-20 and △T are the temperature deviations 5 and 20 centimeters deep in the soil and the earth-atmosphere temperature deviation respectively, the correlation ratio of this formula is 0. 879 and the mean fitting error is only 1. 4 wm-2. By calculating the soil heat flux from 215 stations over China and analyzing their time and space variations, we have acquired some significent results.更多还原
