摘要

[目的] 探究不同初始含水率和雨强对红壤大团聚体溅蚀特征和溅蚀过程的影响，为理解和防控红壤大团聚体溅蚀过程提供科学依据。[方法] 选取红壤大团聚体(2～5 mm)为研究对象，通过人工模拟降雨试验，探讨4个雨强(30，60，90，140 mm/h)和4个初始含水率(10%，20%，30%、饱和)下团聚体溅蚀量和溅蚀率的变化规律。[结果] ①相同初始含水率下，红壤大团聚体溅蚀量在4个雨强下的变化范围分别是0.05～0.27，0.03～0.19，0.16～1.41和0.03～1.48 g。②相同雨强下，饱和初始含水率下的团聚体溅蚀量均显著增大(p＜0.05)。③在4个雨强下，饱和初始含水率下的团聚体溅蚀量相较于非饱和初始含水率下(10%，20%和30%)的溅蚀量总和分别增大1.50，1.11，3.80，3.21倍。④初始含水率、雨强及其交互作用对团聚体溅蚀量均产生直接正向影响，效应值分别为0.646，0.415，0.361。[结论] 在20%初始含水率下，雨强增大对红壤大团聚体溅蚀作用不明显。在其他初始含水率条件下，红壤大团聚体的溅蚀量对雨强变化敏感，在强降雨(90 mm/h)或极端暴雨(140 mm/h)条件下更易受到溅蚀作用的影响。相同雨强下，饱和初始含水率会加剧溅蚀作用的发生和强度。红壤大团聚体溅蚀量与初始含水率和雨强间呈良好的幂函数关系，初始含水率是影响溅蚀量的关键因素。

Abstract

[Objective] The effects of different initial moisture content and rainfall intensities on the splashing characteristics and processes of red soil macro-aggregates were explored

in order to provide a scientific basis for understanding and preventing the splash erosion process of red soil macro-aggregates. [Methods] Red soil macro-aggregates (2—5 mm) were selected for study. Artificially simulated rainfall experiments were conducted to explore the variation patterns of splash erosion and splash erosion rate with four rainfall intensities (30

and 140 mm/h) and four initial moisture content levels of moisture content (10%

20%

30%

and saturation). [Results] ① Under the same initial moisture content

the ranges of splash erosion amount for macro-aggregates of red soil at four different rainfall intensities were from 0.05 to 0.27 g

from 0.03 to 0.19 g

from 0.16 to 1.41 g

and from 0.03 to 1.48 g. ② At the same rainfall intensity

the splash erosion of the aggregates under saturated initial moisture conditions all increased significantly (p＜0.05). ③ At the four rainfall intensities

the splash erosion of the aggregates under saturated initial moisture conditions increased by 1.50

1.11

3.80

3.21 times

respectively

compared to the sum of the splash erosion under unsaturated initial moisture conditions (10%

20%

and 30%). ④ The initial moisture content

rainfall intensity

and their interaction all exerted direct positive effects on the splash erosion of the aggregates

with effect sizes of 0.646

0.415

and 0.361

respectively. [Conclusion] At an initial moisture content of 20%

an increase in rainfall intensity did not significantly impact the splash erosion of red soil macro-aggregates. Under other initial moisture content conditions

the splash erosion of the red soil macro-aggregates was sensitive to changes in rainfall intensity at the same initial moisture content. Macro-aggregates of red soil were more susceptible to the impact of splash erosion under heavy rainfall (90 mm/h) or extreme rainfall (140 mm/h). At the same rainfall intensity

the saturated initial moisture content increased the occurrence and severity of splash erosion. The initial moisture content and rainfall intensity showed significant

positive correlations with changes in red soil macro-aggregates. Additionally

the initial moisture content was a key factor influencing splash erosion.
