| Abstract: | The soil and water conservation effect of Eulaliopsis binata planted at Jinsha River watershed was studied.The results showed that compared with the barren land,planting Eulaliopsis binata could decrease the soil bulk density by 0.10 kg/cm~(3),increase the total soil porosity by 9.6 % and raise water holding capacity of soil by 22.03 %.The effect of improving the physical characters of soil and increasing the water conservation ability is significant. |
