The structural properties of water transport channel and storage space in hillslope soil body units determine its function of water storage and water supply. Systematic analysis of the structural properties and functional attributes of water transport channels and storage space in hillslope soil body units

is a major basic scientific issue needsto be solved urgently in the process of multi-level water networks

especially the “capillary water networks” construction. The article takes the effect of water transport storage function as the starting point

analyzes the water transport channels and storage space functional attributes of slope soil units

reviews the identification methods of water transport storage structure

water regulation and supply capacity evaluation methods of slope soil units

and looks forward to the future development direction of water transport storage function evaluation. The research results aim to provide theoretical and technical support for the assessment of water storage and supply capacity on mountainous slopes and the construction of “capillary water networks”.
