Soil infiltration properties (SIPs) are important components of forest hydrological responses; however, few studies have investigated the mechanisms through which soil physical affect SIPs. In this study, two SIPs, initial rate (IIR) and saturated hydraulic conductivity (Ks), were quantified at five depths (0–10, 10–20, 20–30, 30–40, 40–50 cm) in three stands (pine (Pinus taeda), oak (Quercus acutissima), bamboo (Phyllostachys edulis) forests). We constructed a structural equation model (SEM) to analyze main affecting SIPs their influence pathways, results show that IIR Ks values for whole profile decreased as follows: pine > forest. total porosity (STP), field capacity (SFC), capillary water holding (CMC), (SWC), content (ISWC) positively correlated with while bulk density (SBD) was negatively The SEM indicated positive driver STP, sand SBD reduced infiltration. texture indirectly affected by mediating SWC. These provide data support simulation subsurface responses forests significant implications management.
