摘要
应用小区观测资料，对南方红壤坡地几种典型治理措施的径流调控效应进行了分析研究。结果表明，与裸地比较，水土保持植物措施的径流调控效益达到21．1％～94．2％，顺坡与横坡耕作措施的径流调控效益分别达到59．7％和72．3％；在其它措施相同的条件下，南方普遍采用的梯田、水平竹节沟、鱼鳞坑这3种水土保持坡面工程措施，径流调控效益均在68．3％以上；与单一措施比较，工程措施与植物措施、耕作措施优化组合的综合性水土保持措施，径流调控效益高达91．6％，这些优化组合的水土保持措施可在南方红壤区因地制宜地广泛推广。
With observation data of runoff plots, the paper analyzed the effects of several typical measures on regula- ting 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 measures such as terraces, level ditches, and fish-scale pits, which are widely adopted in the south of China, were above 68.3%. Compared with single measures, the effect of com- prehensive measures of engineering measures with vegetation measures and tillage measures to runoff reduc- tion reached 91.6 %, and comprehensive measures should be widely popularized in the south of China.
