摘 要:
针对单一径流调控措施难以得到较好水土保持效果的问题，本研究通过天然降雨径流、产沙的试验定位观测，对几种措施复合后的次降雨径流、产沙的调控率，及对作物产量的影响做了分析。研究表明：复合措施可以有效地对坡面径流、产沙进行调控，减少坡面径流量和产沙量90％以上，同时提高农作物的产量10％以上。复合措施因其优异的径流、产沙调控能力，增产明显，成本低廉，实施简便，成为一种性价比较高的坡面径流调控模式。[著者文摘]

Abstract:
Since the single regulating measure is not good enough in water and soil conservation, this study analyzed the effects of corn yield, regulating rates of runoff and silt caused by different compound regulating measures at the natural raining. The results showed that： the regulating measures could effectively control the runoff and silt on sloping fields. They could decrease the runoff and silt from sloping fields obviously, and increase the crop yield at the same time. We found that corn ＋ PAM was a good compound regulating measure for the control of the sloping runoff and silt because it was cheap in cost, easy to carry out and could control the runoff and silt from sloping fields and increase yield effectively at the same time.[著者文摘]
