Xinjiang is a large district suffering from soil and water loss in China
but soil erosion processes in the region have not yet been under stood deeply.Taking San'gong River water shed in Fukang City
Xinjiang Wei Autonomous Region
as an example
a preliminary study for the distribution characteristics of waterstable aggregate content and its influence factors was performed to provide an important basis for soil erosion control.Soils of 0-20 cm and 20-50 cm on a typical hilly slope
slopes of different gradients
and vegetation converage of different degrees were analyzed.Results showed that the dist ribution of soil water stable aggregates in the small watershed had the following characteristics:it had a decreasing tendency from surface down to bottom in the same soil profile;on the same slope
it had a increasing tendency from top to bottom;and on slopes of different gradients
it had a decreasing tendency with slope increasing.In terms of the water stable aggregate content under vegetation coverage of different degrees
landuse was in the descendant order of sloping cropland
