Growing contour hedgerows on slopelands is an effective way to control soil erosion and nutrient loss.The experimental data of simulated rainfalls on a slope land(25°)of purplish soil in the Three-Gorge-Reservoir Region indicated that the Vetiveria zizanioides contour hedgerow plots decreased 82.2% in soil loss as compared with the cultivated plot.Fertilization did good to the growth of hedgerows and hence the effect of erosion control;which was comparable to the mulching treatment.The most distinct variation in slope shape between hedgerows was the formation nearly alluvial strips.With changing slope shape and increasing interception by hedgerows,the interacting time between soil and runoff was prolonged.As nutrient loss in runoffs,is an important way,hedgerows' function of controling runoff loss is helpful in decreasing soil erosion and nutrient loss by hedgerows.
