In comparison with barren slope

a pilot study of hydrology effect of artificial woodland surface soil in semi-arid low mountainous upland region of western Liaoning province was carried out.The results indicate that soil bulk density is minimum in Vitex negundo forest

it is maximal in P.simonii forest;Soil total porosity

capillary porosity and non-capillary porosity in Vitex negundo forest are maximal

they are minimum in P.ssimonii forest;soil water storage

effective capacity and capillary water holding capacity of surface soil in woodland are higher than barren slope

soil water storage

effective capacity and capillary water holding capacity in Vitex negundo forest are maximal

they are minimum in P.simonii forest

soil water storage range from 701.8~1 328.4 t/hm2

effective capacity range from 41.2~411.6 t/hm2

capillary water holding capacity range from 660.6~916.8 t/hm2;Infiltration capacity of surface soil in woodland is better

steady infiltration rate in Vitex negundo forest is maximal

it is minimum in P.ssimonii forest

steady infiltration rate range from 0.03~6.11mm/min

there is a significant positive correlation between steady infiltration rate and the total porosity

so as steady infiltration rate and non-capillary porosity

there is power function connection between soil infiltration rate and time;According to function of soil and water conservation in woodland surface soil

we can put the following items as such orders: Vitex negundo forest>Prunus sibirica-Vitex negundo mixed>Pinus sylvestnis var.mongolica forest hillclosed and afforested>Larix principis-rupprechtii forest>P.tabulaeformis-Vitex negundo mixed forest>H.rhamnoides forest>P.simonii forest.
