摘　　要：通过研究黄花菜处理组（T1）及对照组（CK）间土壤的含水量，探求植物篱技术对表层土壤水分的影响。结果表明：各对照组之间土壤含水量差异不显著，而经过黄花菜植物篱技术处理之后的土壤含水量有所增加；各处理组的坡面在次降雨条件下产生细沟侵蚀的时间不同，发生细沟侵蚀的时间对照组要晚于黄花菜植物篱处理组。从坡上至坡下表层0-5cm土壤的临界含水量有逐渐增加的趋势。Based on the analyses of other scientists, this search discovered that the hedgerows technology had great effect on the surface soil moisture（SSM）. The experiments show that there is no significant difference of SSM among the control groups, but in the slopes in which planted hemercoallis citina baron the SSM incroases;the time that rill erosion brokes out is different in different slops after artificial rainfall, and the time of control group is earlier than that of hemercoallis citina baron groups. Threshold soil moisture increases gradually from the top to bottom in the surface soil（0-5 cm） in the slop.
