Soil anti-scourability for four different land uses in the Dry-Warm Valleys of the Jinsha River Basin was studied by the flume experiment.The anti-scourability of surface soil increased with time
and the relationships for the land uses can be fitted by power function.The anti-scourability followed the order of stable gully>active gully>cultivated land>bare land.The ratio of the mean values of soil anti-scourability was 1.0:1.4:3.0:21.5 for stable gully
active gully
cultivated land and bare land
respectively.The same relationships held for subsurface soil in the period of the first 5 minute infiltration.Grass roots play an effective role in increasing soil anti-scourability. Soil anti-scouring ability is closely related to soil organic matter
and the content of>0.25 mm water-stable aggregate size fractions (especially of 3~5 mm
