土壤侵蚀问题,尤其是降雨造成的侵蚀及相应的泥沙淤积、斜坡失稳等问题,已成为当今世界上最严重的问题之一。多年来,人们尝试利用植被(草或树)来减轻侵蚀,稳定斜坡。一种可以明显提高斜坡稳定性、减轻侵蚀的独特植物——香根草正在引起有关方面重视。香根草生长旺盛、根系深扎,兼有树木和草本的特性,可以防止侵蚀,控制地面土粒的浅层移
Soil erosion, especially the erosion caused by rainfall, the corresponding sedimentation and slope instability, have become one of the most serious problems in the world today. Over the years, people have tried to use vegetation (grass or trees) to reduce erosion and stabilize the slopes. A unique plant that can significantly improve slope stability and reduce erosion - vetiver is attracting attention. Strong growth of vetiver roots deep junctions, both the characteristics of trees and herbs, can prevent erosion, control of soil surface shallow movement
