Soil water is a critical factor of eco-environmental construction and land exploitation.Based on the fixed observation in the immigrant demonstration area of Nort hwest Guangxi Province from April to September in 2006
the dynamic change of soil water on hillslope with various landuse types was analyzed.Results showed that the dynamic change of soil water storage had the similar trend with the change of rainfall.In temporal scale
soil water storage in 0-1 m layer had the significant differences among various land use types.Landuse types rankes in the decreasing order of slope farmland
orchard land
wasteland
natural shrub land
and arbor woodland.In spatial scale
soil water storage on hillslope was in moderate variation and had some differences among various landuse types.Soil water storage of grassland and shrub land was higher in 0-20 cm layer
but it was higher on slope farmland and orchard land in 60-100 cm layer.Soil wa- ter had the increasing trend from the top down to the bottom along the hillslope with the different land use struct u res.However
the range of variation for soil moist ure along the hillslope with contour terrace was smaller than that of natural slope.
