G.E.Hubb root is from 0.20mm to 0.50mm, and 95% roots, diameter is thinner than 0.40mm. The total surface areas of roots is 10139.68cm^2, and the surface areas of roots is about 2 to 3 times to soil surface areas in the surface layer. Enlacing sod concretion to soil profile of Eulaliopsis binata G.E. Hubb root and the gigantic adsorption to soil grains of root surface are the mechanism why Eulaliopsis binata G.E. Hubb can reduce null and water loss significantly. The monitoring result from 2003 to 2004 indicates that, when the gradient is 12 degrees, the runoff rate of planting Eulaliopsis binata Retz. G.E. Hubb completely after changing slope land to ladder (PECC, so as the follows is only 49.90m^3/hm^2?yr. and the soil loss rate is 155.78kg/hm^2?yr, however, the runoff rate of fanning and being not change slope land to ladder is 314.29m^3/hm^2?yr that is 6.30 times to PECC ,and the soil loss rate is 3322.50 that is 21.33 times to PECC; When the gradient is 24 degrees, the runoff rate of planting eulaliopsis binata G.E, Hubb in the ridge and border slope land after changing slope land to ladder is 248.04m^3/hm^3?yr and the soil loss rate is 612.00kg/hm^3?yr. the runoff rate of PECC is only 42.44m^3/hm^2?yr and the soil loss rate is 153.75kg/hm^2?yr, however, the runoff rate of ENC reaches to 785.73m^3/hm62?yr that is 3.17 times to PERBC and 18.52 times to PECC, and the soil lose rate reaches to 37503m^3/hm^2 yr that is 61.33 times to PERBC and 244.12 times to PECC.

蓑草根系平均直径0.20~0.50mm， 95%的根系平均直径小于0.40mm，根系总表面积10139.68cm^2，在土壤表层根系表面积高达土体表面积的2~3倍，根系表面对土壤颗粒的巨大吸附作用是蓑草显著提高土壤抗侵蚀能力的另一个重要原因。2003~2004年的监测结果表明，在12度坡度情况下，坡改梯后净作蓑草年径流量仅49.90立方公尺/hm^2，年土壤流失量为155.78kg/hm^2，而未坡改梯且农作情况下，年径流量314.29立方公尺／hm^2为前者的6.30倍，年土壤流失量3322.50Kg/hm^2为前者的21.33倍；在24度坡度情况下，坡改梯后土埂及边坡种植蓑草、坡面农作年径流量248.04立方公尺/hm^2，年土壤流失量612.00kg/hm^2，坡改梯后净作蓑草径流量42.44立方公尺/hm^2，土坡流失量l53.75kg/hm^2，而未坡改梯且农作情况下年径流量高达785.73立方公尺/hm^2，分别为处理1的3.17倍，处理2的18.52倍，年土壤流失量高达37503kg/hm^2，分别为处理1的61.33倍，处理2的244.12倍。
