The benefit of soil and water conservation of Eulaliopsis binata

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．
