| 英文摘要 | As soil ecosystem engineers, ants considerably affect soil physical and chemical properties, and further accordingly affect soil erosion. However, few study was made on studying the effects of ant-burrowing activities on soil erosion previously. This study quantified the impacts of ant (Camponottis japonicus)-burrowing activities on runoff and soil erosion rates. Simulated laboratory rainfall experiments were undertaken on six soil tanks filled with clay-loam soil classified as a cumulic anthrosol, three of which introduced with ant colonies for two days and the other three were without ant colonies, under 40, 80, and 120 mm h(-1) of rainfall intensities and a slope of 15 degrees. Results showed that ants made mounds with a bulk density of 0.75 g cm(-3), which was lower than that of the soil matrix, i.e. 1.34 g cm(-3). Soil erosion rates for the tanks with ants were 6.78, 36.90, and 62.00 g m(-2) min(-1) under three rainfall intensities of 40, 80, and 120 mm h(-1), which were much higher than those of 3.94, 23.49, and 44.48 g m(-2) min(-1) for the tanks without ants. Ant nests reduced the runoff rate by 31%, 20% and 13% compared with those without ants and enhanced the soil water storage within 90 cm depth. Ant nests played a positive role in soil water conservation due to the large nest entrance diameter and the continuous macropore network. However, the ant mounds provided a loose erodible material and changed micro-topography of the slope surface, thereby accelerating the rill formation and exacerbating soil erosion. This study can help understand the effects of burrowing insects on soil erosion, which is an important environmental problem on the Loess Plateau. |
