Abstract:: In order to provide the scientific basis to sustainable healthy development of shrub land in steep slope on loess region in northern Shaanxi, rain, interception, runoff, natural precipitation infiltration depth and soil water dynamics in peashrub forest on sloping land in loess region of Northern Shaanxi had observed at fixed position from 2006 to 2008 continuously. The results indicated: interception of shrub land in steep slope accounts for 11.73% of the total rainfall; runoff accounts for 16.275% of mean precipitation; natural precipitation infiltration depth is 120 cm; relationship between natural precipitation and soil water supply, between soil water supply and density, between soil water consumption and density are all tested linear relationship. In this region the peashrub density carrying was 2 852 clump/hm² on sloping land. We propose to control density suitable, uses the rain water resources reasonably, achieve sustainable and healthy development of peashrub forest land on steep slope.
