Other Abstract

 The runoff and sediment of three approaches (bare land,contour cultivation,level terrace) in the
northeast gully watershed were observed. The relationship between runoff,sediment and rainfall and other fac-
tors were studied. The Canonical Correlation Analysis method were used to analysis the soil erosion characteris-
tics. Under the bare land and contour tillage approaches,runoff depth played a main role in theⅠtypical vari-
able. Under the level terrace measure,soil erosion modulus played a main role in theⅠtypical variable. Re-
dundant index analysis showed that under the approaches of bare land and level terrace,theⅠtypical variables
in soil erosion characteristic factor could be well predicted by erosion impact factors,but the impact factors of
soil erosion under the three measures were not predicted well by erosion characteristics factors. In the bare
land and level terrace,the rainfall,rainfall intensity and antecedent soil moisture and other erosion factors
could predict runoff and soil erosion modulus. While in high tillage,soil erosion factors to predict the charac-
teristics of soil erosion factor is more accurate with the rainfall,rainfall intensity,rainfall erosion force
