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.
