摘要

通过室内人工模拟降雨的方法，研究不同树龄金银花对片麻岩坡地土壤侵蚀的影响。结果表明：种植金银花能明显减缓雨水对片麻岩坡地的土壤侵蚀。金银花能延迟初始产流时间，降低径流模数和输沙模数，且随树龄的增加效果明显增加。相比裸地，种植1，3，6年树龄金银花分别延迟产流时间0.71%，23.33%和39.20%；6年金银花降低径流模数和径流深分别达75%和51%，降低输沙模数为23.42%~57.60%。金银花能提高土壤抗侵蚀能力，相比裸地，种植1，3，6年树龄金银花坡面WAS0.25分别提高11.52%，19.37%和24.35%。在近根区，相比1年树龄金银花根系生物量，种植3，6年金银花依次增加82.67%和191.26%。根系生物量与金银花坡面的总减流率和总减沙率呈极显著正相关，其相关系数（R2）分别为0.801和0.911。总体上，金银花能够控制片麻岩坡地土壤侵蚀，并在一定程度上提高土壤抗侵蚀能力。

Abstract

The effects of honeysuckles with different ages on soil erosion on gneiss slopes were studied using artificial rainfall simulation. Results showed that planting honeysuckle significantly reduced soil erosion by rain water on gneiss slopes. Honeysuckle delayed initial runoff time

reduced runoff modulus and sediment transport modulus. Moreover

the effects increased with the increasing ages of the honeysuckles. Compared with bare soil

the one-

three-and six-year-old honeysuckles delayed runoff time by 0.71%

23.33% and 39.20% respectively; the six-year honeysuckles reduced runoff modulus and runoff depth by 75% and 51%

respectively

and reduced sediment transport modulus by 23.42%~57.60%. Honeysuckle also improved soil erosion resistance. Compared with bare soil

the WAS0.25 of the one-

three-and six-year-old honeysuckles on slopes increased by 11.52%

19.37% and 24.35% respectively. Compared with the one-year-old honeysuckles

root biomass of the three-year and six-year honeysuckles increased by 82.67% and 191.26% respectively in the near-root zone. Honeysuckle root biomass was strongly and positively correlated with the total flow reduction rates (R2=0.801) and total sediment reduction rates (R2=0.911). In general

honeysuckle could control soil erosion on gneiss slopes and improve soil erosion resistance to some extent.
