In order to make better the ecological function of mountain forest land and improve the ability of forest water conservation in this area, six typical forest stands in Northern Mountain of Hebei Province were selected as the research samples. Meanwhile the author analyzed and compared the soil physical properties by ring knife method. The results showed that: (1) the soil bulk density was positively correlated with soil depth, soil bulk density average decreased in the orger: Larix principis-rupprechti forest (1.20 g/cm3) > Quercus mongolica forest (1.14 g/cm3) > Pinus tabulaeformis forest (1.12 g/cm3) > Betula davurica forest (1.03 g/cm3) > Betula platyphylla forest (0.98 g/cm3) > Populus davidiana forest (0.81 g/cm3); (2) the total soil porosity was negatively correlated with soil depth and the average order of total porosity was: Populus davidiana forest (57.6%) > Betula platyphylla forest (51.4%) > Betula davurica forest (51.1%) > Pinus tabulaeformis forest (49.1%) > Larix gmelinii-rupprechti forest (45.9%) > Quercus mongolica forest (44.8%);Populus davidiana forest’s average soil capillary porosity was maximum(48.9%), Pinus tabulaeformis forest was minimum (35.1%); The maximum non-capillary porosity averages was Pinus tabulaeformis forest (14.0%), the minimum was Betula platyphylla forest (3.6%); (3) there was a negative correlation between soil moisture and soil depth, The maximum water holding capacity of the soil was Populus davidiana forest and the smallest is Larix gmelinii-rupprechti forest; (4) the relationship between soil infiltration rate and infiltration time followed the power function. The largest steady infiltration rate was Pinus tabulaeformis forest (15.00 mm/min) and the minimum was Larix gmelinii-rupprechti forest (0.68 mm/min). The research results can provide the basis for sustainable utilization of forest soil resources.
