Abstract

Abstract: For solving the difficult problems of quantitative description on migration complexity and spatial inhomogeneity of seasonal frozen soil moisture during frozen-thaw process, soil moisture profile of different stages in seasonal frozen soil region was taken as the research object and geostatistics was performed to study its spatial variability. The results indicated that soil profile moisture of different stages had good spatial structure and strong spatial correlation. Seasonal frozen-thaw process weakened the spatial correlation of soil profile moisture and had intense spatial redistribution effects on it. The application of geostatistics can provide a new thought and method for the research on soil moisture migration mechanism during frozen-thaw process in seasonal frozen soil region.
