| 摘 要： | 摘要2010年实验结果表明：大别山南麓黄棕壤坡地采用种植行距为2m的香根草等高绿篱水土保持措施，可使地表径流量和土壤侵蚀量分别减少46．7％、75．8％以上；可使临界侵蚀量增加50．6％；可使土壤分散率降低28．1％；可使水稳性团聚体增加27．6％。说明香根草等高绿篱能有效地防治大别山南麓黄棕壤坡地水土流失。

| Abstract: | Experimental results show that in 2010, after the plantation of the vetiver contour hedges with row space of 2m as the soil conservation measures on the Dabie Mountains yellow - brown slope, the surface runoff and soil erosion were reduced by 46.7% and 75.8% respectively, and the critical erosion was increased by 50.6% , the soil disper- sion rate was decreased by 28.1% and the water stable aggregates was increased by 27.6%. It means that the vetiver contour hedges cad effectively prevent the soil erosion of yellow - brown slope farmland at the southern foot of Dabie Mountains. |
