本文采用一种野外实地测量土壤热扩散率结合室内测定该土壤热容量的方法，计算实际情况下土壤热惯量值与水分含量间的关系。文中对该测量方法进行了推导，并将之应用于黄淮海地区不同土壤类型中，在给出不同土壤类型和质地的热惯量值的同时，对该方法的重复性、稳定性、准确性进行了检验。
In this paper, a field measurement of soil thermal diffusivity combined with indoor determination of the soil thermal capacity method to calculate the actual situation of soil thermal inertia value and the relationship between moisture content. The measurement method was deduced and applied to different soil types in the Huang-Huai-Hai region. The thermal inertia values of different soil types and textures were given, and the repeatability, stability and accuracy of the method were also studied The test.
