地物热惯量是应用遥感技术进行地表热量平衡过程研究的一个重要参数，它是地物密度、热容量和热传导系数的函数．提出了一种利用土壤热通量板、红外测温仪、数据采集器等附加装置，在土壤遮阳降温过程中连续快速地测定土壤热通量和土壤红外辐射温度来估算土壤热惯量的新方法．通过对３种不同水分含量的土壤样本进行热惯量测定的试验，其结果很理想，从而确定了这种土壤热惯量测定新方法的可行性，同时在测定技术上也是一种新的尝试．
Surface thermal inertia is an important parameter for the study of the surface thermal balance process using remote sensing technology. It is a function of the density, heat capacity and thermal conductivity of the object. A new method for estimating soil thermal inertia by using soil heat flux plate, infrared thermometer and data acquisition device to measure the soil heat flux and soil infrared radiation temperature continuously and rapidly in the process of sun-shading and cooling was proposed. . The results of thermal inertia test of soil samples with three different moisture contents are very satisfactory, so that the feasibility of this new method for determining thermal inertia of soil is confirmed. At the same time, it is also a new attempt in measuring technology.
