中文摘要 | 基于坡面不同植被措施下多场室外人工模拟降雨试验,采用通径分析和灰色关联理论研究了植被、降雨及下垫面等因素对坡面次降雨径流总量和泥沙总量的不同影响作用。结果表明:1)通径分析与灰色关联分析结果基本一致;2)降雨强度、植被覆盖度和土壤前期含水量是影响坡面次降雨径流总量的3个最重要因子,其次分别为植被类型、降雨历时、植被生长阶段和坡度;3)植被覆盖度和降雨强度是影响次降雨泥沙总量最重要的两个因子,降雨历时对泥沙总量的影响作用最小。 |
英文摘要 | Based on vegetated-slopes and outdoor simulated rainfall events, the different influence of vegetation, rainfall, underlying surface condition on the total runoff amount and total sediment yield for one rainfall event was investigated by path analysis and grey relational analysis. Results indicated that the results of path analysis are in agreement with that of grey relational analysis. The rainfall intensity, vegetation coverage and antecedent soil moisture are the three most important factors that influence the total runoff amount, and followed by vegetation types, rainfall duration, vegetation growth stages and slope gradient. The vegetation coverage and rainfall intensity are the two important factors that influence the total sediment yield, and rainfall duration is the least significant factor. |
