| 摘 要： | 植物根系增加土壤的抗侵蚀能力主要通过两种方式一是通过根系在土体中交错、穿插,网络固持土壤;二是通过改善土壤的物理性质,提高土壤自身的水力学性质,从而增强土体的抗侵蚀能力.植物根系能明显增强土壤的抗冲性、土壤的渗透性及土体的剪切强度等水力学性质.根系在提高土壤抗侵蚀能力、防止土壤侵蚀方面具有重要作用.

| Abstract: | There are two ways for plant roots to improve soil capability of anti-erosion. One is that fine root can keep soil by its net-work;The other is that roots can improve soil physical properties. The both ways can strengthen soil Hydraulic properties, and im-prove the capability of soil anti-erosion. Plant roots can improve soil anti-scourability, soil penetrability and anti-shear strength. Plant roots play an important role in improving soil anti-erosion capability and in preventing soil losses. |
