摘　　要：等高植物篱模式就是在坡耕地上每隔4—8m的距离沿等高线将植物篱与作物种植带相间分布的一种农林复合经营模式，用于坡耕地的水土保持。已有的研究结果表明，等高植物篱技术用于坡耕地可有效地改善土壤物理性质和土壤水分状况，防治坡耕地水土流失效果显著，土壤水分的季节性再分配也有利于农作物的生长。但是该系统内植物篱和农作物相互之间的水分和养分关系有待深入研究。Contour hedgerow intercropping as a type of agroforestry system, in which double - row hedges are planted along contour line in slopelands spaced 4 -8 m, has been promoted for erosion control, soil fertility amelioration, and soil water storage in tropical mountain areas. From the foregone research results, soil physical properties and hydraulic parameters under the contour hedgerow system were ameliorated to certain extent and soil moisture regime was improved. Effects of hedgerow on soil erosion control had proven to be very effective. However, it was far from fully understanding the pattern of soil water redistribution and utilization of temporal and spatial regime between hedgerows and crops.
