Reforestation plays an important role in soil conservation and soil carbon sequestration.Five types of artificial vegetation were selected in the Wangdonggou watershed located in the hill and gully area of the Loess Plateau to understand the influences of artificial vegetation on soil properties.Soil moisture

soil or- ganic C(SOC)

and total soil nit rogen were investigated under different types of vegetation.During dry sea- son

there was the intense water consumption characteristic in locust tree forest land and soil water content below the 200 cm depth ranged from 5.8% to 7.1%

showing a decrease wit h depth.Compared to grass- land

Chinese pine forest land had a soil water content of 15% in the same layer.Soil moist ure used for ori- ental arbor-vitae

sea-buckthorn

and apple was mainly distributed between 20 and 200 cm from soil surface.Although natural rainfall had a supplement to the forest land

soil water within 50 cm of soil surface was recharged in rainy season.Compared with grassland

SOC content was increased by 9.3% for Chinese pine and decreased by 40.1% for orchard.SOC contents of sea-buckthorn

oriental arbor-vitae

and locust tree were lower than those on grassland

although not significantly.
