| 摘 要： | 为研究植物根系对边滩坡面固土抗冲性的影响,选择麦冬草、芦苇和蒿草3种天然植物进行抗冲性物理试验,测量植物种植密度、根系面积比率和冲刷量。试验结果表明,根系发达、根系面积比率大的植物对滩坡的固土护岸作用大且范围广,防护效果好,并给出了根系纵深分布一般公式以及稳定坡面的地形函数。

| Abstract: | In order to study the influence of plant root system on erosion resistance of the slope bank,different kinds of natural plants like ophiopogon japonicus,reed and wormwood are applied in the erosion experiments.Experimental parameters of root density,root area ratio and erosion quantity were measured.The experimental results show that the more developed of root system and the larger of the maximum root area ratio(RAR) value,the more effects it will take on the bank protection and wider range.Besides,a general formula about depth distribution of the root system and function about stable slope are obtained. |

| Keywords: | plant root system root area ratio flood plain erosion resistance stable slope |
