金沙江流域龙须草的水土保持效应研究初报

Preliminary Research Report on Soil and Water Conservation Effect of Eulaliopsis binata in Jinsha River Watershed

对金沙江流域龙须草地水土保持效应的研究结果表明,与空旷地相比种植龙须草可降低土壤容重0.10 g/cm3,增加土壤总孔隙度9.6%,提高土壤贮水率22.03%,其改善土壤的物理性状,提高土壤蓄水能力的效果显著。

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.
