热异常分布原因地壳上部的热场,既取决于太阳的辐射,也取决于地球内部的热源。太阳辐射传播的深度,与活动层的底部是一致的。在没有地表水下渗的地方,变温层底部的埋深大致是相同的;而在有地表水下渗并渗得很深的地方,中性层的空间位置即发生变化。在这种情况下,温度场的变化是受运动着的水的温度所控制的,而不受太阳热的控制。 Thermal Abnormal Distribution Causes The thermal field above the crust depends on both the solar radiation and the heat inside the Earth. The depth of the solar radiation propagation is consistent with the bottom of the active layer. In the absence of subsurface seepage, the depth of the bottom of the thermal layer is roughly the same; however, where there is deep seepage through the surface water, the spatial position of the neutral layer changes. In this case, the change in the temperature field is controlled by the temperature of the moving water and not by the solar heat.
