Abstract:The paper focused on soil infiltration rate and soil moisture content under 12 different land uses in semiarid region of loess.The results showed that soil moisture content was about twice under the same land uses in the farmland-sloping,which was significant difference.The gap was about 35.23% in the drought terrace,5.84% in the hillsides,no obvious difference was found in the ditch platform.Artificial vegetation played an obvious role in improving soil moisture content.When infiltration continued 180 minutes,contrast to unculivated land the soil moisture content of Poplar plantation,enclosed grassland,Caragana plantation,Seabuckthorn plantation,Plnus plantation,mixed plantation was 108.19%,173.43%,157.76%,192.28%,93.64%,129.67% respectively.Soil moisture content in the artificial shrub lands,such as seabuckthorn forests,caragana lin,was larger than artificial arboreal lands.The way of plough in hillsides was an effective measure in soil and water conservation.Soil bulk density acted as an active index affected soil moisture content,which soil bulk density was bigger,soil moisture content was smaller.Soil infiltration rate was 9.60%~19.02%,which would not affect soil moisture content.
