With observation data of runoff plots, the paper analyzed the effects of several typical measures on regulating runoff in slope land of red soil in south china.The results showed that compared with the bare plot,the effect of vegetation measures to runoff reduction was 21.1%-94.2%,the effects of down-slope tillage and contour tillage to runoff reduction were 59.7%and 72.3%,repectively.Under the same condition of other measures,the effects of engineering widely adopted in the south of China measures such as terraces level ditches and fish-scale pits,which are were above 68.3%.Compared with single measures,the effect of comprehensive measures of engineering measures with vegetation measures and tillage measures to runoff reduction reached 91.6%,and comprehensive measures should be widely popularized in the south of China.
