龙须草水土保持效益研究

The benefit of soil and water conservation of Eulaliopsis binata

摘要: 对龙须草地水土保持效益研究结果表明，与空旷地相比种植龙须草可降低土壤容重0．13g／cm³，增加土壤总孑L隙度4．9％，提高土层土壤贮水量14．9％，年土壤侵蚀量472．7t／km²，比对照减少94.5％，生态效益和经济效益显著。

Abstract: The study on the benefit of soi1 and water conservation of Eulaliopsis binata was conducted，showing that compared with the barren land，the plantation of Eulaliopsis binata decreases the soil bulk density by 0．13g／cm³，increases the total soil porosity by 4．9％．raises the water-holding capacity of soil by 14．9％，reduces the soil erosion amount by 472．7 t／km³．So,the economical and ecological benefits of Eulaliopsis binata planted in slope wasteland are remarkable．
