| 摘 要： | 芨芨草是黄土高原地区广泛分布的禾本科植物.人们对其水土保持方面的定量研究基本上还处于空白.通过对芨芨草草地土壤抗冲性、渗透性、土壤抗剪强度等指标的研究,来探讨芨芨草的水土保持功能.结果表明:芨芨草能明显提高土壤的抗冲性、渗透性及土壤的抗剪强度,并能增加地表的覆盖度.芨芨草在黄土高原地区的水土保持工作中有着广阔的应用前景.

| Abstract: | Achnatherum splendens, belongs to the grass family, largely distributes in Loess Plateau. However, few quantitative studies on its soil and water conservation have were. To probe into the effects of Achnatherum splendens on soil and water conservation, soil anti-scourbility and penetrability and anti-shear strength are measured. The result shows that Achnatherum splendens can improve such soil features and increase the degree of land coverage, so it can be widely used for soil and water conservation purpose in Loess Plateau. |
