中文摘要：

利用变温层温度序列获得大地热流与利用浅海或湖底连续观测的沉积物温度序列求解浅海或湖底沉积物热流时,对序列中来自大气或海水的高频温度信息的处理及浅地表介质热性质的获取都涉及到浅层地表热传输方面知识的运用.本文在将国内外浅层地表热量传输领域整体知识梳理的基础上,首先介绍了比较有代表性的五类浅地表传热模型,两类典型的土壤体积热容量计算公式、常用的四类求热扩散率的方法以及五种热导率参数化方案,及简要回顾了热通量的求解方法,并概述了每种方法的主要特点及应用状况.文中指出,今后的工作中,可以考虑建立耦合热传导-对流的多层传热模型,上边界条件可尝试先从定常温度的基础上叠加一个谐波到一组谐波,且采用各层交界面满足热性质相同的边界条件来模拟土壤的传热过程.对于较深层土壤或岩石,常用的热导率参数化方案及土壤体积热容量计算方法已不太适用,可考虑通过开发更精准的传热模型来模拟深层热物性参数以弥补其实验数据上的不足.

英文摘要：

Shallow ground heat transfer theory,which focuses on the heat transfer process form surface to a depth of a dozen meters below ground.The top of the Earth media in this depth contacts to the atmosphere,and the bottom contacts to the interior of the earth.The temperature record observed in shallow ground consists of two parts,the one is high frequency noises caused by influences from temperature changes above Earth＇s surface,the other one is Earth＇s internal heat information.Removing the external high-frequency noises and water Bottom Temperature Variation（BTV）,and obtaining the complicated thermal properties of some media must under the precisely understanding of the shallow ground heat transfer theory,when using thermocline temperature sequences to obtain heat flow and continuously observed sediment temperature sequence in shallow sea or lake bottom to solve the sediment heat flow.The main points of the shallow ground heat transfer study are the soil temperature,heat flux calculations,and the methods for deriving the soil thermal property.On the basis of reviewing the integral knowledge of shallow ground heat transfer at home and abroad,this paper firstly systematically introduces five representative models of Shallow Ground Heat Transfer,two typical calculation formulas of soil volumetric heat capacity,four commonly used methods on the deriving thermal diffusivity,five algorithms of soil thermal conductivity and briefly reviewed the calculation methods on soil heat flux.Then,outlines the main feature and application status of each method.Finally,the main study directions of shallow ground heat transfer under practical application are presented.It is stressed that,model building for coupled heat transfer and heat convection should be employed in future work. On the treatment of upper boundary condition,adding harmonic-group on steady state temperature is better.The paper also suggests that thermal conductivity parameterization and algorithms of soil volumetric heat capacity would lose effectiveness in de
