中文摘要	为有效防治坡耕地水土流失，提高坡耕地持续利用，于2007年选用甘草、板蓝根两种道地药材，在陇中黄土高原半干旱区的坡耕地上进行了道地药材保护性耕作防治水土流失效应的研究。试验设传统耕作下板蓝根与甘草间作（T_(IL)）、春小麦与甘草间作（T_(WL)）、免耕不覆盖下板蓝根与甘草间作（NT_(IL)）、春小麦与甘草间作（NT_(WL)）、免耕秸秆覆盖下板蓝根与甘草间作（NTS_(WL)）、春小麦与甘草间作（NTS_(WL)）6个处理，坡度在6°～7°之间，每个处理小区底部设径流收集池。结果表明：（1）保护性耕作具有良好的防止土壤侵蚀效应，6个处理的水土流失量为T_(WL)〉NT_(WL)〉NTS_(WL)〉T_(IL)〉NT_(IL)〉NTS_(WL)。（2）流失泥沙的养分含量中有机质、速效N、速效P、速效K的流失总量最大，全N和全P的流失总量最小，NTS_(WL)对减少有机质和速效K的流失具有明显的作用。（3）径流量、侵蚀量与降雨量的回归关系均十分显著。所以在坡耕地上选择板蓝根与甘草间作的水土保持效果优于春小麦与甘草间作，尤其以NTS_(WL)最佳。
英文摘要	In order to reduce soil and water losses in sloping fields and improve sustainability on fragile slopes, the field experiment was conducted in 2007, in the semi-arid region of west Loess Plateau in Gansu province and the effect of conservation T_(IL)lage of genuine traditional chinese drugs on soil erosion in sloping fields was analyzed. Six treatments including conventional T_(IL)lage of indigowoad root/liquorice intercropping （T_(IL)） and spring wheat/ liquorice intercropping （T_(WL)）, no-T_(IL)lage with no stubble retention of indigowoad root/liquorice intercropping （NT_(IL)） and spring wheat/liquorice intercropping （NT_(WL)）, no-T_(IL)lage with stubble retention of indigowoad root/ liquorice intercropping （NTS_(WL)） and spring wheat/liquorice intercropping （NTS_(WL)）, with three replications which had slopes ranging from 6° to 7°, were investigated. The ponds of runoff and sediment were placed at the bottom of each plots. The results showed that：（1） Conservation T_(IL)lage has significant effection to prevent soil erosion, the total amounts of runoff and soil loss of six treatments were T_(WL)〉NT_(WL)〉NTS_(WL)〉T_(IL).〉NT_(IL)〉NTS_(WL). （2） The total loss of organic matter, available N, available P, available K in the nutrients of sediment loss is maximum, but the total loss of whole N and whole P is minimum, and NTS_(WL) has obvious function to reduce the loss of organic matter and available K. （3） The regression relation among runoff, sediment yield and rainfall are very notable. It showed that the impact of soil and water conservation in indigowoad root/liquorice intercropping was su perior than spring wheat/liquorice intercropping, and the NTS_(WL) was the best of six treatments.
