摘要

[目的] 为明确风力作用下迎风坡坡面细沟侵蚀特征。[方法] 采用人工模拟风驱雨试验

研究在不同风速条件(0

7 m/s)下迎风坡坡面水沙过程变化规律及细沟形态特征。[结果] 与无风坡面相比

迎风坡面产流时间和跌坎出现时间分别增加20.59%~47.06%和33.10%~137.78%

坡面平均流速减小12.86%~22.53%;产流率和产沙率随风速的增加而显著减少(p＜0.05)

不同风速条件下

迎风坡面产流率变化趋势相近

随着降雨进行产流率逐渐增加

一段时间后保持稳定

不同风速下的阶段性无明显差异。产沙率随降雨历时的延长整体呈先迅速增加后缓慢下降并趋于稳定趋势

产沙率发生变化的节点与跌坎出现时间基本一致。细沟宽度、深度及其波动程度随着风速的增加而减小;细沟宽度、深度及其波动程度随着风速增加而减小;细沟宽深比和细沟倾斜度分别为1.40~1.69和13.47°~14.76°

均随着风速的增加而增大;不同风速条件下

细沟体积、细沟割裂度和细沟密度分别为4.39×103~10.27×103 cm3

0.024~0.042

2.03~2.92 m/m2

三者均随风速的增加而减小。[结论] 细沟体积、细沟密度和割裂度与坡面侵蚀量均呈极显著正相关关系

是表征迎风坡坡面细沟形态的优选指标。

Abstract

[Objective] This study was aimed to elucidate wind-induced rill erosion characteristics on the windward slope. [Methods] Artificial simulated wind-driven rain experiments were conducted. The study investigated changes in water and sediment processes as well as rill morphology under different wind speed conditions (0

and 7 m/s). [Results] Compared to slopes without wind

the windward slope exhibited a 20.59%~47.06% increase in flow generation time and a 33.10%~137.78% increase in the occurrence of falling ridges. The average slope flow velocity decreased by 12.86%~22.53%. Runoff and sediment production rates notably decreased with increasing wind speed (p < 0.05). The runoff production rate on windward slopes followed a similar trend under different wind speeds

gradually increasing with rainfall before stabilizing over time

with no significant differences observed among stages at different wind speeds. Sediment yield rates increased rapidly with prolonged rainfall duration

followed by a gradual decrease and stabilization. Nodes of sediment yield rate changes aligned closely with the occurrence of falling ridges. Rill dimensions (width

depth

fluctuation degree) decreased with rising wind speed. The width-depth ratio and rill inclination ranged from 1.40 to 1.69 and 13.47 to 14.76 degrees

respectively

increasing with higher wind speeds. Under various wind speed conditions

rill volume

splitting degree

and density ranged from 4.39 to 10.27 cm3

0.024 to 0.042

and 2.03 to 2.92 m/m2

respectively

all decreasing with increasing wind speed. [Conclusion] The volume

density and degree of fragmentation of rills are all significantly positively correlated with the amount of slope erosion

making them the preferred indicators for characterizing the morphology of rills on windward slopes.
