中文摘要：

我们试图在 0.8， 1.6，和 3.2 m 的深度从 177 个观察的点的长期的温度观察计算表面平均的热流动(SAHF ) ，它均匀地相对在大陆中国被散布。我们首先采用 Fourier 转变把大气的温度变化的影响从观察系列移开，它被分类进单调地与深度增加的不变的温度的类型(类型我) 并且另外的三种类型。然后，我们比较我们从类型的数据获得的结果我，哪个值吝啬的地上凿穿热流动被认为到平等者到那些，与从传统的热获得的那些，流动观察主要在诺思中国 Craton 散布了。在在观察车站的 SAHF 的计算，当第一走，我们由为一样的潮湿组采用热传导方程的泛音答案推出热扩散性和土壤的容量的特定的热，然后我们用 Fouriers 法律决定 SAHF。我们的结果显示 SAHF 从地热的数据能反映的浅土导出热流动地到大程度。

英文摘要：

We attempt to compute the Surface Average Heat Flow （SAHF） from long-term temperature observations of one hundred seventy-seven observational points at the depths of 0.8, 1.6, and 3.2 m, which were relatively evenly distributed in mainland China. We first employ Fourier transformation to remove the influence of atmospheric temperature variations from the observation series, which are classified into the type of the steady-state temperature monotonously increasing with depth （type I） and other three types. Then we compare our results obtained from the data of type I, of which the values are thought to equal to those of the mean borehole heat flow, with those obtained from traditional heat flow observations mainly distributed in North China Craton. In computations of the SAHF at the observation stations, we deduce the thermal diffusivity and volumetric specific heat of the soil by employing harmonic solutions of the heat conduction equation for the same moisture group as the first step, and then we determine the SAHF using Fourier＇s law. Our results indicate that the SAHF derived from shallow earth geothermal data can reflect the heat flow field to a large extent.
