Abstract:: Based on soil hydrology physical properties, water holding capacity and infiltration, the water storage and infiltration capacity were analyzed in typical forest stands in down south of Xiaoxing’an Mountains, and Kostiakov equation, Horton equation and Philip equation were used to simulate the soil infiltration processes. The results showed that soil bulk density was between 0.45~1.52 g/cm³, and soil saturated moisture contents of different vegetation types were between 28.73%~177.32%, capillary moisture contents were 25.26%~156.84%, the natural moisture contents were 13.91%~119.18%, and these three parameters obviously decreased with increase of soil depth;the range of soil maximum storage capacity was 282.88~341.41 mm, effective capacity was 27.88~61.13 mm, retention ability of precipitation was 165.98~197.37 mm (except for artificial Larix gmelini forest of 76.32 mm). Soil initial infiltration rate and steady infiltration rate of each vegetation type were the largest in 0—10 cm or 10—20 cm soil layer, the average value was 11.92 mm/min and 2.78 mm/min, respectively, and their minimum values in different vegetation types present in different soil layers, with average value of 2.19 mm/min and 0.66 mm/min. According to the soil infiltration process simulation, Horton equation was better for this simulation.
