Research on Spatial Variability Characteristics of Black Soil Unfrozen Water in Songnen Plain during Freezing-Thawing Period

Abstract : To address the difficulties of the complexity and the quantitative description of spatial non-homogeneity in the process of freezing and thawing of soil moisture migration, taking the unfrozen water as the research object, and using geostatistics to study the spatial variability characteristics of unfrozen soil water in different freezing and thawing stages. The results show that different freezing and thawing stages of unfrozen soil water has good spatial structure and strong spatial correlation, and it has a strong spatial redistribution effect on soil moisture. The application of geostatistics provides a new train of thought for in-depth study on freezing-thawing process of soil moisture transport mechanism.
