摘　　要：[目的]分析油茶林梯壁上套种黄花菜植物篱的生态效应。[方法]以未套种黄花菜为对照(CK),设计对比试验,采用打桩法测定土壤流失量,并测定土壤容重、渗透性和含水量。[结果]2014—2017年套种黄花菜的油茶林(YH)较CK处理土壤流失厚度减少0.52 cm,YH处理与CK处理土壤流失厚度间存在极显著差异;各土层均以YH处理土壤地温低于CK处理。0~20 cm土层土壤容重,YH处理较CK处理降低5.1%,非毛管孔隙度、总孔隙度分别较CK处理增加25.2%和7.5%,土壤含水量增加18.6%,20~40 cm土层也有同样变化规律。[结论]油茶林梯壁上套种黄花菜具有明显的生态效益。[Objective] To study the ecological effect of Camellia forest terrace wall interplanting daylily as hedgerow. [ Method ] To design com- parison test, taking without daylily as control （CK）.Soil loss was measured by piling method, the soil bulk density, pemreability and water con- tent were also measmed. [ Result] From 2014 to 2017,the Camellia tbrest （YH） interplanting daylily 1educed the soil loss thickness by 0.52 em compared with CK treatment ,there was a significant dittbrenee between YH treatment and CK treatment in soil loss thickness.The ground tempera- ture of each soil layer treated with YH was lower than CK treatment.Soil bulk density of 0-20 em soil layer, YH treatment deereased by 5.1% compared with CK treatment.Non-eapillary porosity and total porosity inereased by 25.2% and 7.5%, respeetively, eompared with CK treatment, soil water content increased by 18.6%.The soil layer of 20-40 cm also had the same change rure. [ Conclusion] There are obvious ecological bene- fits in Camellia torest ten＇ace wall interplanting daylily.
