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。

The experiment is began with the runoff quality on the diverse roofage and different grade roadway, the results are as follows:(1) The concentration of contamination is different with the diverse roofage, and SS value is also different with the style roof;(2) In the beginning , the concentration of COD value and SS value is higher ,but the runoff quality will be reduced to steady gradually along with the rainfall duration increase;(3) The city roadway runoff is worse than the roadway of university ,because the city roadway runoff involve vehicle n people and the sanitation and material of roadway;(4) Based on the analysis of rainwater quality , the paper provide the process of rainwater treatment for roof, roadway, and lawn.

对教学区内不同建筑物，及道路上的雨水径流水质进行监测，得出以下结论：(1)材料不同，径流雨水中污染物浓度不同，屋顶类型不同，径流雨水中SS浓度亦不同；(2)初期径流污染物浓度很高，随降雨历时的延长，COD和SS浓度逐渐下降并趋于稳定；(3)道路污染与路面材料、来往车辆、人员流动、路面卫生状况有关。市区道路相比校园内道路，水质较差；(4)对雨水水质分析基础上，分别对建筑屋顶、道路、绿地提出雨水利用的处理工艺。

The wavelet variance verification also indicates that the first main period of the runoff of mountainous watershed in the Shiyang River Basin is 30years, and 22years and l5years are the second and third period respectively; 3 Then we also compared the total runoff of mountain watershed with climate factors of Wushaoling which station is in the mountain headstream area, such as precipitation and temperature, the data record that the correlation coefficient of annual runoff and precipitation variation over the upper reaches in the Shiyang River Basin is 0.61 ,which indicates precipitation is the main water recharge of the runoff.

石羊河流域出山口年径流的周期变化与乌鞘岭站年降水量和年均气温周期基本上都能在同一周期上下浮动，其中出山口年径流量与乌鞘岭山区年降水量相关系数为0.61，说明地表径流量主要是由山区降水补给；年径流量与山区年均气温变化呈0.28的反相关，说明该流域近50年来出山口径流与山区气温呈反比，即径流量随年均气温上升而减少，相关性暂时不十分明显。

与runoff相关的网络解释 [注：此内容来源于网络，仅供参考]

runoff：径流

林区可以通过吸收雨水和截取地表径流(runoff)(过剩的雨水)来减少水土流失. 树木的根系将土壤固定在它所在的地方,防止湖床和河道出现阻塞. 林区对于雨水的吸收还能帮助地下水补给并防止洪水的爆发. 森林是世界上氧气的主要来源,

runoff：决定性竞选

如果普选还不能决定最终结果,那么还有决定性竞选(runoff). 到了投票日(polling day),选民(voter)就会把填好的选票放进投票箱(ballot box). 在选举中的投票通常都是不记名投票(secret vote / anonymous ballot).

runoff：迳流

当骤雨来临时,红土层如无森林的保护及吸收,则大部分的雨水将成为表面迳流(runoff),顺著山坡向下游流走. 而砾石层如无森林的保护而裸露在外时,则对於雨水的侵蚀就毫无抵抗之力了,未固结的砂粒很容易被雨滴直接冲击而跳失,

runoff：径流量

本世纪相类似的大范围干旱可能会引起:碳存储量及动力学的巨大改变,近地面的太阳辐射量的不稳定,径流量(runoff)和侵蚀(erosion)形式的变化,也会引起在土地和气候之间的微气候反馈(microclimate feedback)的变化,

surface runoff：地表径流

过去识别出的河谷网络似乎是地下河的杰作,但这些新发现的河谷却有些不同,它们的特征看似出自降雨、融雪或地表径流(surface runoff)的手笔. 比如,这些网络支流密布,从源头到末端,河谷的长度和宽度不断递增. 而且,河道的源头都分布在山脊顶部,
