| 摘 要： | 通过室内人工模拟降雨,分别对种植柠条锦鸡儿、披碱草的两个坡面土槽及一个裸地坡面土槽进行不同降雨强度、降雨历时以及不同季节的降雨试验,试验得出边坡种植柠条锦鸡儿和披碱草后降雨的产流量、产流历时、径流转化率等指标,按柠条锦鸡儿、披碱草、裸地顺序递增,雨后土壤含水量的变化是按裸地、柠条锦鸡儿、披碱草顺序递减。该项试验结果,对于进一步研究黄土植被边坡护坡水文效应、评价草本和灌木植物护坡贡献,以及有效防治水土流失、滑坡等浅层地质灾害的发生,具有重要的理论研究价值和实际指导意义。 |
| 关 键 词： | 模拟降雨 降雨入渗 黄土边坡 产流 |

| Abstract: | Under the condition of indoor artificial rainfall simulation,experiments are carried out regarding rainfall intensity,rainfall duration during different seasons in two soil ditches planted with Caragana korshinskii and Elymus dahuricus and one bare dirt ditch.It is concluded that after planting Caragana korshinskii and Elymus dahuricus,the rainfall runoff yield,runoff duration and runoff transformation rate are in an increasing order,that is: Caragana korshinskii |
| Keywords: | simulated rainfall rainfall infiltration loess slope runoff |
