Clarifying the runoff and sediment in runoff plot under different soil and water loss control patterns plays an important role for large-scale soil and water loss. In this study

the runoff and sediment of red soil under three typical soil and water loss control patterns (S1 pattern: slope change ladder + Fruit trees

S2 pattern: contour trench and ridge + Crops

S3 pattern: flat wasteland slope + Herbs) were investigated through the field standard runoff areas under natural rainfall experiment in low hilly areas. The results showed that the average runoff volume under three control patterns was S3 (1.84?m3) > S1 (1.03?m3) > S2 pattern (0.78?m3)

and the average sediment yield was S3 (1.191?t/hm2) > S1 (0.411?t/hm2) > S2 pattern (0.311?t/hm2). The cumulative runoff under the three control patterns was S3 (33.19

15.25

14.13?m3) > S1 (19.40

9.06

6.48?m3) > S2 pattern (16.60

5.89

4.15?m3) in the A

B

and C rainfall types (K-means clustering). The cumulative sediment also showed the similar trend that was S3 (14.474

10.863

15.153?t/hm2) > S1 (7.521

2.695

3.766?t/hm2) > S2 pattern (6.149

1.685

2.741?t/hm2). Different control patterns maintained a significant positive correlation between sediment yield had significant positive correlations with runoff volume under the tree control patterns (P<0.01

r > 0). The correlation coefficient (r) was 0.853

0.920

and 0.677

respectively. Furthermore

the linear regression slope (k) of sediment yield and runoff volume was 0.356

0.420 and 0.493

respectively under S1

S2

and S3 patterns

indicating the response degree of sediment to runoff in different control patterns was S3 > S2 > S1 pattern. Thus

three typical patterns have significantly different effects for controlling soil and water loss.
